FireBeetle Board ESP32-E (Arduino Compatible)

The FireBeetle Board ESP32-E is a compact IoT development board based on the ESP-WROOM-32E module with a Tensilica LX6 dual-core processor running at 240MHz. It supports Wi-Fi 802.11 b/g/n and Bluetooth 4.2 (BR/EDR + BLE) for versatile wireless connectivity.

Designed for ultra-low power IoT applications, the board draws as little as 10µA in deep sleep. It features an on-board LiPo charging circuit with PH2.0 battery connector, a GDI display port, an RGB LED, and a stamp-hole design for direct PCB embedding. Arduino IDE compatible with one-click upload.
