Introduction

Note: This guide is specific to the ESP32 Thing Plus (USB-C) board variant. For the variants with the USB micro-B connector, please refer to the ESP32 Thing Plus hookup guide.

The SparkFun ESP32-WROOM Thing Plus (USB-C) enjoys all the features of our previous ESP32 Thing Plus (Micro-B) boards, but with a few improvements. For this variant, we have included a SD card slot, upgraded to a USB-C connector, integrated a RGB status LED and battery fuel gauge, and provided two voltage regulators; offering separate 700mA current sources for the board and Qwiic connector. The board still retains its standardized 28-pin Feather footprint, 2-pin JST battery connector, and Qwiic connector like our other Thing Plus boards.

The ESP32-WROOM module on the board provides a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I2S, and I2C. With Espressif's ESP32 comprehensive development platform and Bluetooth low-energy support (i.e BLE, BT4.0, Bluetooth Smart) these boards are jam packed with possibilities!

Note: The CH340C serial-to-UART bridge is used on this board. Therefore, a different driver installation is required from previous versions of the ESP32 Thing Plus.

Not Yet Implemented: The Arduino core for the ESP32 microcontroller are still a work in progress. There are a handful of peripherals and features that have yet to be implemented, including:

The peripherals are available (if, also, still in their infancy) in the IoT Development Framework for the ESP32. If your application requires any of the features above, consider giving the ESP-IDF a try! (Updated: June 2022.)

Required Materials

To get started, users will need a few items. Now some users may have a few of these items, feel free to modify your cart accordingly.

  • SparkFun Thing Plus - ESP32 WROOM (USB-C)
  • USB 3.1 Cable A to C - 3 Foot - The USB interface serves two purposes: it powers the board and allows users to upload programs. (*If your computer doesn't have a USB-A slot, then choose an appropriate cable or adapter.)
  • Computer with the an operating system (OS) that is compatible with all the software installation requirements.

How to Work with Jumper Pads and PCB Traces

April 2, 2018

Handling PCB jumper pads and traces is an essential skill. Learn how to cut a PCB trace, add a solder jumper between pads to reroute connections, and repair a trace with the green wire method if a trace is damaged.

Headers & Accessories

Headers are great for development purposes, letting users swap parts with just a set of jumper wires. If you would like to add headers to your board, check out some of the options for the Thing Plus or Feather form factor boards below.
