Freematics ESPRIT-C3 is an Espressif ESP32-C3 RISC-V development board in Arduino UNO form factor with extra I2C, UART, JTAG interfaces.
Freematics Esprit leads out nearly all useful ESP32’s GPIO pins, arranged in a deliberated order, to balance between accessibility and Arduino compatibility.
Extra pinouts In addition to standard Arduino pin headers as following.
The VCC switch toggles between 3.3V and 5V for VCC pins for serial UART header and xBee socket. The VCC/GND pins on UART header can be used to power the board when switched to 5V by Freematics OBD-II UART adapter. The standard xBee socket VCC voltage is 3.3V, while all our cellular modules require 5V VCC.
