Overview
Product introduction
ESP32-C3-MINI-1-TB and ESP32-C3-MINI-1U-TB are two entry-level development boards for developing and testing small-sized ESP32-C3-MINI-1 & ESP32-C3-MINI-1U modules. This group of development boards has complete Wi-Fi and Bluetooth low energy functions, and most of the pins of the modules on the board have been led out to the pin headers on both sides. Developers can easily connect various peripherals through jumpers according to actual needs. The device can also be used by plugging the development board into the breadboard.
Parameters
Components introduction
Components and interfaces
Note: For specific function instructions, please refer to the user manual of ESP32-C3-MINI-1.
Pin Definition
The following positive illustration shows the ESP32-C3-MINI-1-TB as an example:
Notes
- P: power supply; I: input; O: output; T: can be set to high impedance.
- GPIO2, GPIO8, and GPIO9 are the strapping pins of the ESP32-C3FN4 chip. During chip power-on and system reset, the strapping pin controls the chip function according to the binary voltage value of the pin. For the specific description and application of the strapping pins, please refer to the chapter on strapping pins in the ESP32-C3 chip manual.
- The power supply mode is Micro-USB interface power supply (default), 5V and GND pin header power supply, 3 and V3 and GND pin header power supply.
