Features: 1. The ESP32 DevKitC development board adopts the mainstream TYPE-C interface, and the motherboard can be equipped with ESP32 modules: ESP-WROOM-32, ESP-WROOM-32D, ESP-WROOM-32U, ESP32 WROVER. 3. ESP32 DevKitC is a small development board based on the ESP32 module, supporting Wi Fi and Bluetooth functions, with rich peripherals, allowing users to easily develop products. 4. The onboard LDO is led out and can power external components. ESP32 DevKitC groups different peripheral interfaces to help users easily get started with product development. Parameter: ESP32 DevKitC Development Board: Module based on ESP32 EN: Reset button. Boot: Download button. Press and hold the Boot key, while pressing the EN key once (do not release the Boot key at this time) to enter the Firmware Download mode and download the firmware through the serial port. USB-to-UART bridge: A single chip USB-UART bridge that can provide a transmission rate of up to 3 Mbps. Interface: TYPE-C interface, which can be used as a power supply for circuit boards or as a communication interface between PC and ESP32-WROOM-32 modules.
