MicroMod Teensy Processor Hookup Guide
Hardware Overview
We'll cover the hardware and components included on the MicroMod Teensy Processor Board in this section and highlight some of their unique features.
M.2 Connector
All of our MicroMod Processor come equipped with the M.2 MicroMod Connector, which leverages the M.2 standard and specification to allow you to install your MicroMod Processor on your choice of Carrier Board.

The M.2 MicroMod connector is keyed (in tandem with the set screw notch) to prevent the Processor from being inserted and secured improperly.
NXP iMXRT1062 Processor
The brain of the MicroMod Teensy Processor is the NXP iMXRT1062 from NXP Semiconductors. This Arm Cortex-M7 core processor is one of the most powerful microprocessors available today. The MicroMod Teensy Processor board takes advantage of the following properties:
- ARM Cortex-M7 at 600MHz
- Seven Serial Ports
- 2 SPI ports (One dedicated SPI available by default on most Carrier Boards[1]. Dedicated Hardware SDIO for SD.)
- 4 I2C Bus (One I2C bus available by default on most Carrier Boards[1])
- USB Host Capability up to 480Mbit/sec making it capable of interfacing with USB flash drives, mice, keyboards and more.
- USB Device Capability up to 480Mbit/sec making it capable of interfacing with USB keyboard/mouse/joystick, MIDI, audio and more.
- 1 CAN Bus Interface
- I2S Digital Audio and S/PDIF
- 12 Dedicated GPIO
- 14 Analog pins (2 dedicated, 10 share signals.)
- 3.3V-tolerant I/O pins
- 16MB Flash Memory (256K reserved for recover & EEPROM emulation)
- 1024K RAM Memory (512K is tightly coupled)
Flash IC
The MicroMod Teensy Processor uses the W25Q128JV-DTR serial flash memory IC from Windbond Electronics. The flash IC features 128mb of memory. For a detailed overview of the IC, refer to the datasheet.
LEDs
There are two LEDs on the Teensy Processor. The PROG LED indicates when the HalfKay bootloader is enabled and the programming IC is powered. We'll cover how to enter the bootloader in the Software Setup and Arduino Example sections. The STAT LED is tied to SCK/13 and can be used as a status LED or as a built-in LED. Control it directly by writing to LED_BUILTIN
.
Measure Jumper
The Measure (MEAS) Jumper can be opened to measure how much current the Teensy Processor is pulling from V_USB. It's is CLOSED by default and ties the USB_VBUS pins to V_USB. Open it by severing the trace and then using a digital multimeter to measure the current draw.
Teensy Processor Pin Functions
The Teensy Processor is similar to the Teensy 4.0 and 4.1 with a few notable differences. In order to maintain easy interoperability with MicroMod Carrier Boards, not all of the alternate pin functions are defined for the MicroMod Teensy board variant but we have done our best to make the Teensy Processor as versatile as possible with the right Carrier Board. The sections below outline the various signal protocols available on the MicroMod Teensy.
I2C
As you may have guessed from our extensive Qwiic System, we love communicating with devices using I2C! The Teensy Processor features four I2C buses. The main I2C bus has dedicated pins connected to MiroMod pads 12 (SDA) and 14 (SCL) (Teensy pins 18 and 19), along with a dedicated interrupt pin connected to MicroMod pad 16 (Teensy pin 29). The primary I2C Bus will almost always be connected to a Qwiic connector on your Carrier Board.
If you need a second I2C bus, the Teensy has SDA1 and SCL1 on MicroMod pads 53 and 51 (Teensy pins 25 and 24). To use this second bus, initialize it by calling Wire1.begin();
.
UART
The Teensy Processor is capable of having seven UARTs available. The primary UART is tied to USB_D± (MicroMod pads 3 and 5) for serial communication over USB. This is used for your standard serial upload as well as serial prints in Arduino. The secondary UART is a hardware UART tied to MicroMod pads 19 (RX1) and 17 (TX1) (Teensy pins 0 and 1). The tertiary UART is another hardware UART tied to MicroMod pads 20 (RX2) and 22 (TX2) (Teensy pins 17 and 16). In Arduino, the three UARTs are called as listed below:
Serial
- Communication over USBSerial1
- Communication over RX1/TX1Serial2
- Communication over RX2/TX2
SPI
The Teensy Processor has multiple SPI ports. The primary SPI connects to the following pins:
- SDI/CIPO - Serial data input (Controller In/Peripheral Out). MicroMod pad 61. Teensy pin 12.
- SDO/COPI - Serial data output (Controller Out/Peripheral In). MicroMod pad 59. Teensy pin 11.
- SCK - SPI Clock. MicroMod pad 57. Teensy pin 13.
- CS - Chip select. MicroMod pad 55. Teensy pin 10.
SPI Pins: The table below summarizes the SPI objects configured in the Arduino SPI library for the Teensy MicroMod processor board. The numbers in the table correlate with the:
- Pins numbers defined for the Teensy MicroMod processor board in the Arduino IDE
- Pad numbers of the MicroMod connector on a MicroMod processor board

Pin Conflict: In order to prioritize the SDIO functionality of the Teensy processor boards's pin assignment, we had to sacrificed the functionality to the MicroMod connector's SPI1 bus. This was due to the hardware limitations of the microcontroller; since, none of the available SPI buses aligned with the MicroMod connector's SPI1 bus (yellow). With that clarified, please do not confuse the SPI1 bus of the standardized MicroMod connector with SPI1
of the Arduino SPI library.

Additionally, some users may recognize that the pins for the SPI2
object are available on the SDIO pads of the MicroMod connector. While the connections don't align with the SPI1 bus of the MicroMod standard, the functionality of SPI2
can be accessed using the Arduino SPI library with carrier boards, where the pins are available (i.e. ATP Carrier Board).
CAN-Bus
One of the unique features of the Teensy is its ability to communicate with CAN devices. The Teensy MicroMod can receive CAN messages but in order to send them properly you will need a separate CAN transceiver. CAN-RX is tied to MicroMod pad 41 (Teensy pin 30) and CAN-TX is tied to MicroMod pad 43 (Teensy pin 31).
AUDIO
The Teensy Processor supports audio using the I2S standard. The pins used are:
- AUD_OUT - GPIO pin 7, pad 56 on the MicroMod, this is the digital audio output.
- AUD_IN - GPIO pin 8, pad 54 on the MicroMod, this is the digital audio input.
- AUD_LRCLK - GPIO pin 20, pad 52 on the MicroMod. Officially called "word select", and also known as "frame sync".
- AUD_BCLK - GPIO pin 21, pad 50 on the MicroMod. Offically called "continuous serial clock, and also known as the "bit clock"
GPIO/BUS
The MicroMod Teensy has all 12 general purpose IO pins available on top of 6 dedicated pins for digital, analog and PWM signals. The dedicated pins are just that, and are not shared with any other pin, unlike the general purpose pins which may be shared with other pins. Take note that not all GPIO pins are broken out or in use on every carrier board. Refer to your Carrier Board's Hookup Guide for more information on pin use.

Extra Teensy Functionality
As experienced users may know, the pins on Teensy development boards are very versatile and can be used for a multitude of purposes. As we noted above, in order to maintain compatibility with the rest of the MicroMod system, not all of these alternate functions are available on the MicroMod Teensy but some pins can be configured for things like Analog Inputs or Pulse Width Modulation. As mentioned before, the best way to interact with these pins is with the ATP Carrier Board.
The list below shows all 14 pins on the Teensy Processor available for use as Analog Inputs.

The default MicroMod Teensy Processor board definition is limited to these extra functionalities along with a few other pins that can technically be used for PWM signals when not in use for other signal protocols. Keep reading to the next section, MicroMod Pinout, for specific information on these pins.
MicroMod Pinout
Refer to the datasheet and user manual for a full overview of the iMXRT1062's capabilities. The complete pin map can be found in the table below or you can refer to the schematic. PJRC has a wealth of knowledge on their forums with regard to the beta testing of the MicroMod Teensy. Here is a specific post that goes into detail about the pin map.
Heads up! The pin table below and schematic both include the Teensy pin associated with each MicroMod pin and this correlation can be used to identify alternate uses for pins on the Teensy Processor but not all of the alternate Teensy functionalities are available for use with the SparkFun Teensy MicroMod board definition. For many of the General Purpose I/O pins and other pins with multiple signal options, refer to your Carrier Board's Hookup Guide for information on how those pins are configured what they are used for. Not all pins are used on every Carrier Board.
Update: Please use the latest version of the Teensy Arduino core, when referencing this table. There have been some small updates to the pin definitions.
