LILYGO T-Energy-S3 ESP32-S3 Dev Board Features An 18650 Battery Holder

LILYGO T-Energy-S3 is an ESP32-S3 WiFi and Bluetooth-enabled IoT development board with an 18650 battery holder, a USB-C port for charging and programming, and plenty of I/Os thanks to two 20-pin GPIO headers and a Qwiic connector. The main attraction of this board is its 18650 battery holder which this dev board can be used for battery-powered applications.

Previously we have written about many similar batter operated development boards like the ESP32 PowerFeather, the Beetle ESP32-C6, the Nessie Circuits Riotee platform, and much more, feel free to check those out if you are looking for similar products.

LILYGO provides documentation for Arduino and PlatformIO, including basic sketches for deep sleep and WiFi station mode, along with a test program for WiFi and GPIOs. The GitHub repository includes datasheets and a PDF schematic. Typically, with LILYGO hardware, you need to develop your own firmware, except for their Meshtastic-compatible boards and devices for messaging and GPS sharing.

LILYGO T-Energy-S3 Can be purchased from Aliexpress where it will cost around $16.98 including shipping.
