LILYGO T7 V1.3 Mini32 ESP32

Overview

The LILYGO T7 V1.3 Mini32 is a low-cost, compact ESP32 development board designed for projects where board size and price are primary constraints. The "Mini 32" designation reflects its reduced footprint while retaining full ESP32 capabilities including dual-core processing, WiFi, and Bluetooth.

The board integrates a TP4054 lithium battery charger, allowing single-cell LiPo batteries to be connected via a JST 2-pin 1.25mm connector. A CH340C USB-to-serial chip handles flashing and serial communication. The 25Q32 provides 4MB of SPI Flash storage for application code and data.

Firmware Compatibility

The T7 Mini32 supports Arduino IDE, ESP-IDF, and MicroPython. Standard ESP32 Arduino core libraries apply. The GitHub repository at LilyGO/ESP32-MINI-32-V1.3 contains example code and pinout diagrams.
