Datasheet

Power Supply Options
There are three mutually exclusive ways to provide power to the board:
• Micro-USB Port, default power supply
• 5V and GND pin headers
• 3V3 and GND pin headers
It is recommended to use the first option: Micro-USB Port.
Header Block
The two tables below provide the Name and Function of the pin headers on both sides of the
board (J1 and J3). The pin header names are shown in ESP32-C3-DevKitC-02 - front. The
numbering is the same as in the ESP32-C3-DevKitC-02 Schematic (PDF).
