SparkFun has introduced a new development board based on the ESP32-C6 chip called “Thing Plus – ESP32-C6.” This board is equipped with the ESP32-C6-WROOM-1-N16 module with 16MB of flash memory and a PCB antenna, as well as a wide selection of inputs/outputs and power options.
The board features 28 mounting holes with support for 23 multifunctional GPIOs and a Qwiic connector for expandability. It supports both 5V battery power and LiPo power through the USB-C port and a 2-pin JST connector connected to the charging circuit and charge level indicator.
Specifications of the SparkFun Thing Plus – ESP32-C6 board:
– Wireless module – ESP32-C6-WROOM-1-N16
– MCU – single-core ESP32-C6 RISC-V microcontroller operating at 2.4 GHz with support for Wi-Fi 6, Bluetooth 5 LE, and 802.15.4 radio (Zigbee and Thread); compatible with Matter
– Memory – 16MB flash
– PCB antenna
– MicroSD card slot
– USB – 1 USB Type-C port for power and programming
– Expandability:
– 12-pin and 16-pin connectors

The ESP32-C6 board is open-source hardware, and SparkFun provides project files (EAGLE and Gerber), some documentation, and datasheets on GitHub. It’s worth noting that the documentation is distributed as MD files, which provide instructions for programming on the Arduino platform.
The market for development boards based on the ESP32-C6 chip is becoming increasingly crowded, ranging from inexpensive WeAct ESP32-C6 modules to DFRobot FireBeetle 2 boards that support LiPo batteries, and Olimex ESP32-C6-EVB boards with additional home automation features, among many others. The “Sparkfun Thing Plus – ESP32-C6” board offers another option, characterized by its larger flash memory (16MB) than most competing products, as well as compatibility with Qwiic modules and the Thing Plus form factor.
The manufacturer offers this board for $19.95 plus shipping costs on their website.
