Hardware Overview

In this section we'll take a closer look at the hardware on this Function Board along with a brief overview of what exactly 10BASE-T1L Single Pair Ethernet is and what benefits it provides.

10BASE-T1L Single Pair Ethernet

The 10BASE-T1L Single Pair Ethernet (SPE) standard uses just a single twisted pair for data as well as power. 10BASE-T1L Ethernet transmits data at speeds up to 10Mbps at distances up to 1.7km. With just a single pair, the cable is smaller and lighter making it ideal for remote monitoring or industrial applications connecting a large number of edge devices to a network connection.

For more information about 10BASE-T1L SPE, refer to this article on the communication protocol from Analog Devices or this SparkFun news post.

ADIN1110

The ADIN1110 is an ultra-low power Ethernet transceiver for 10BASE-T1L IEEE Standard 802.3cg-2019 SPE.

Highlighting the ADIN1110 IC

It operates from a supply voltage of 1.8V or 3.3V. This Function Board runs the ADIN1110 in single-supply mode at 3.3V (VDD_H and VVD_L are both powered at 3.3V) and this allows for transmission amplitude of 2.4V. For a complete overview of the ADIN1110 IC, refer to the datasheet.

The ADIN1110 MAC supports 16 individual MAC addresses and communicates over both Open Alliance and generic SPI protocols. The ADIN1110 transmits data at half duplex when using generic SPI and full duplex when using the Open Alliance protocol. The IC also includes support for three LED outputs, a Link LED and two configurable general purpose LEDs. The Function Board breaks out all of those to LEDs on board. Read on to the LEDs section below for more information.

SPE Data Output

The Function Board routes the ADIN1110's data signal pairs through a TVS diode protection circuit and phase transformer from W├╝rth Elektronik before terminating in a specialized T1 Industrial Jack for connection to a separate SPE device or network hub.

Highlighting SPE Data Output components

For more information about the TZ Industrial Jack, refer to the datasheet.

Power

The Function Board receives power from the Main Board it connects to. The Main Board can be powered either via USB or a connected LiPo battery. Reminder, this Function Board is not designed to send power over the Single Pair Ethernet connection.

LEDs

This Function Board includes four LEDs labeled PWR, LED 0, LED 1 and LINK ST.

Highlighting the LEDs

  • PWR - Power LED.
  • LED 0 - General purpose programmable LED. Active LOW. Default configuration turns the LED on when a link is established and blinks on activity.
  • LED 1 - General purpose programmable LED. Active LOW. Default configuration disables the LED.
  • LINK ST - Link status LED. Active HIGH. LED illuminates with a valid link.

For detailed instructions on programming the general purpose LEDs, refer to the LED Control Register section of the ADIN1110 Datasheet or the SparkFun ADIN1110 Arduino Library.

Solder Jumpers

This function board has twelve solder jumpers. The table below outlines each jumper's label, function, default states and any notes about their use.

Label Default State Function Notes
SHLD CAP (See note) Double jumper to select connector shield grounding option. Default connects the connector shield to ground through a 3.3nF capacitor. Switch to GND side to connect the shield directly to ground.
LED1 CLOSED Completes LED1 configurable LED circuit. Open to disable the labeled LED. Helps reduce the total current draw.
LINKST CLOSED Completes the Link Status LED circuit.
LED0 CLOSED Completes the LED0 configurable LED circuit.
PWR CLOSED Completes the Power LED circuit.
TX2P4 EN OPEN Pulls TX2P4_EN pin LOW. Controls the transmit amplitude mode. By default, this pin is LOW and allows both 1.0V and 2.4V p-p transmit levels. Pulling this pin high disables 2.4V transmit level.1
SWPD EN OPEN Pulls SWPD_EN pin LOW. Controls whether or not the ADIN1110 enters software power-down mode after reset. By default, the ADIN1110 starts autonegotiation after a reset. If the jumper is closed, the ADIN1110 remains in power-down mode after reset until it is configured over SPI. This allows software control over power-down mode.1
MS SEL OPEN Sets the ADIN1110 to operate as a peripheral (slave) device on SPI. Controls whether the ADIN1110 defaults to a controller or peripheral on the SPI bus.1
SPI CFG1 OPEN Sets the ADIN1110 to use OPEN Aliance SPI protocol with protection (if SPI_CFG0 is also LOW).
SPI CFG0 OPEN Sets the ADIN1110 to use OPEN Aliance SPI protocol with protection (if SPI_CFG1 is also LOW).
EWP OPEN EEPROM write protection.
MEAS CLOSED Ties VCC_IN to input on 3.3V voltage regulator. Open to measure current draw of the board.

MicroMod Edge Connector and Pinout

The MicroMod ecosystem uses a polarized M.2 edge connector to provide a standardized electrical connection that is keyed to prevent incorrect connection between MicroMod boards. The attachment points for the screws prevent users from connecting a processor board into a function board slot and vice-versa.

MicroMod Main Board Hookup Guide

November 11, 2021

The MicroMod Main Board - Single and Double are specialized carrier boards that allow you to interface a Processor Board with a Function Board(s). The modular system allows you to add an additional feature(s) to a Processor Board with the help of a Function Board(s). In this tutorial, we will focus on the basic functionality of the Main Board - Single and Main Board - Double.

Single Pair Ethernet Basic Assembly

With the Function and Processor Boards connected to their respective Main Boards, we can complete the assembly of the Single Pair Ethernet circuit. For a basic SPE prototyping circuit either with your own setup or with the Single Pair Ethernet Kit, connect the two MicroMod assemblies together using a Single Pair Ethernet Cable and then power the two MicroMod Main Boards via USB-C like the photo below:

Basic SPE Circuit

Demo Circuit Assembly

We'll be assembling a demo circuit that works with an example pair included in the ADIN1110 Arduino Library that sends environmental data recorded by the SparkFun Atmospheric Sensor Breakout - BME280 (Qwiic) connected to one SPE MicroMod assembly to display on a SparkFun 20x4 SerLCD - RGB Backlight (Qwiic) connected to the opposite SPE MicroMod assembly.

Connect the Qwiic boards to the Qwiic connector on their respective MicroMod Main Boards then plug the SPE cable into the T1 jacks on each Function Board. Once all of those are connected, power the MicroMod Main boards with USB-C cables. The completed demo circuit should look like the photo below:

Now that our demo circuit is complete, we can move on to uploading the code to establish a SPE link and send data between the two MicroMod assemblies.

Software Setup

Note: This library assumes you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino or if you need a refresher, please review the following tutorials.

SparkFun ADIN1110 Arduino Library

The SparkFun ADIN1110 Arduino Library includes several examples to get started communicating between two ADIN1110 Function Boards. The library is hosted on GitHub. Install the library through the Arduino Library Manager tool by searching for "SparkFun ADIN1110 Arduino Library". Users who prefer to manually install it can grab it from the repository or download it directly by clicking the button below:

The SparkFun ADIN1110 Arduino Library includes a wide set of examples to demonstrate different ways to configure and use the ADIN1110. They include basic examples to get up and running as well as advanced examples for users who prefer to customize the performance and memory use in transmissions.

Arduino Examples

The SparkFun ADIN1110 Arduino Library includes several sets of examples to get started communicating between ADIN1110 nodes. In this section we'll take a look at the Arduino example pair for the demo circuit shown in the Hardware Assembly section.

Example Set 3 - Transmit BME280 / Receive LCD Display

Note: This example pair requires two additional libraries; the SparkFun BME280 Library and SparkFun SerLCD Library. Install them through the Arduino Library Manger tool or download them for manual install by clicking the buttons below:

The Example 3 set (3a & 3b) work together to send environmental data from a BME280 connected to the transmitter MicroMod assembly to display on a LCD attached to the receiver MicroMod assembly.

Open an instance of the Arduino IDE for both boards and open the examples by going to File/Examples/SparkFun ADIN1110 Arduino Library/Example 03A_TransmitStrBME280 / 03B_RxStrSerLCD. Take note of the ports for both Processors to keep track of which board is which. Upload the examples to both boards and once a link is confirmed, the boards should start sending/receiving data between each other. If you do not see data or the LINK LEDs lighting up on both Function Boards, open the serial monitor and reset both boards. The code will print out debug data that may help troubleshoot issues with the SPE link.

Example 3A - BME280 Transmit

Example 3A creates the frame parameters for sending data measured by the BME280 and then sends that data over to the receiver every five seconds by default. If the readings from the BME280 change beyond a specified threshold in between reports, the code overrides the five second delay and sends a force report.

Example 3B - LCD Receive

Example 3B readies the ADIN1110 to receive data from the BME280 on the other Function Board and then prints the data to a LCD connected to the MicroMod main board. When starting up, the display will print out "Waiting for connection" and then "Connected" once a link is established. After establishing the link, the display should update with new data every five seconds or more often if the transmit Function Board receives a force update due to large changes in readings from the BME280.

Troubleshooting

Here are a couple of quick troubleshooting tips to use if you run into issues creating a link between ADIN1110's.

Check Board/Library Versions

If you have any issues with the Arduino Library and a SparkFun MicroMod Processor, make sure you have the latest versions of both the Processor Board definitions and the Arduino Library.

Reset Sequence

If the boards do not establish a link when running the example sets from the Arduino library, hold the RESET buttons on the Main Boards down at the same time. Release the RESET button on the receiving board (eg. the LCD circuit for the demo example) first and then release the RESET button on the transmitting after.
