1.1 Features

ESP32-WROOM-32E ESP32-WROOM-32UE

ESP32-WROVER-IE

ESP32-WROVER-IE-TB 、ESP32-WROOM-32E-TB、ESP32-WROOM-32UE-TB are three entry-level development

boards that use the corresponding modules of the ESP32 series as required. The development board has complete

Wi-Fi and Bluetooth low power functions, and most of the pins of the module on the board have been drawn to the

two sides of the pin row, developers can easily connect a variety of peripheral devices through jumper, and can also

plug the development board into the breadboard for use.

Chengdu Ebyte Electronic Technology Co.,Ltd ESP32 series development board User manual

Micro USB connector

The USB port can be used as the power supply for the circuit

board or the communication port for connecting the PC to the

ESP32 series module.

5V Power On LED

When the development board is powered on (USB or external 5

V), the indicator will light up. See schematics in related

documents for more information.

I/O

Most of the pins of the on-board module have been drawn to

the development board's row pins. Users can program ESP32 to

realize PWM, ADC, DAC, I2C, I2S, SPI and other functions.

Note: For specific function instructions, refer to the user manual of the ESP32 series

corresponding module.

Note: 1.P: power supply; I: input; O: output;

2.Pins D0, D1, D2, D3, CMD, and CLK are used for internal communication between th

e ESP32 chip and the SPI flash and are centrally distributed on both sides of the developmen

t board near the USB port. In general, it is best if these pins are not connected, otherwise

they may affect the work of SPI flash/SPI RAM.

3. Pin GPIO16 and GPIO17 are only applicable to the onboard ESP32-WROOM series and

ESP32-SOLO-1 development board. Pin GPIO16 and GPIO17 of the onboard ESP32-WROVER series de

velopment board are reserved for internal use.
