Wemqs WiFi and Bluetooth Battery ESP32 Development Board With 18650 Lithium Battery Shield

ESP32 WiFi + Bluetooth Development Board with 18650 Lithium Battery Charging Shield – Dual-Mode Wireless IoT Module

Unlock powerful IoT development with the WEMOS ESP32 Development Board, featuring integrated WiFi and Bluetooth connectivity, and an onboard 18650 battery charging shield. This compact, feature-rich board is designed for developers and hobbyists looking to build portable and energy-efficient ESP32-based projects.

The ESP32 chip comes with a built-in antenna, RF balun, power amplifier, low-noise amplifier, filters, and power management system — all packed into a minimal PCB footprint. Built using TSMC’s 40nm low-power technology, this module offers superior performance, efficiency, and reliability for a wide range of IoT applications.

When building wireless or battery-powered projects, power becomes a key concern. This board eliminates the need for an external power bank by supporting a standard 18650 lithium battery (not included). With a 3000mAh battery, your ESP32 project can run continuously for up to 17 hours.
