|   |   |

Board is available at Tindie store [![tindie](https://github.com/srg74/WLED-ESP32-dev-board/blob/main/Resources/images/[email protected])](https://www.tindie.com/products/28858/)

This development board features, the powerful ESP-WROOM-32 module, with integrated WiFi and Bluetooth functionality (BR/EDR/BLE). The ESP32 is a chip designed with TSMC ultra-low power management technology.

Current of the ESP32 chip is less than 5 μA, it is particularly well suited for use with batteries or rechargeable batteries. The ESP32 D1 Mini has a similar pin layout to the conventional D1 Mini ESP8266-12F and is therefore pin compatible with most accessories for it. The proven ESP32-D0WDQ6 chip is located in the core of the developed module.

**Specifications:**

- Module: ESP32-Wroom-32

- Chipset: ESP32-D0WDQ6

- USB-TTL CH304

- storage space: 16 MB !!!

- Bt V4.2 (BR/EDR/BLE)

- built-in PCB antenna

- OM: 448 KB - SRAM: 520 KB

- WiFi: 2.4 GHz

- Operating voltage: 5V DC

- CH340 USB-to-serial (USB to UART) controller

- Polyfuse protection

- Boot and Reset button
