ESP32-S3 Development Board with 1.69 IPS LCD Display (240 x 280)

This 1.69′ display development board features a 240MHz dual-core processor, a 240 x 280 pixel LCD display with vibrant 262K colours, and it supports both WiFi and Bluetooth. The board includes a QMI8658 6-axis sensor (accelerometer and gyroscope), a PCF85063 RTC chip, and a lithium battery recharge manager.

Its Type-C connector, 8MB PSRAM, 16MB Flash memory, and various programmable buttons are designed for easy integration into different projects. It is ideal for motion detection, step counting, and custom function development.

Please note: this board uses a tiny MX1.25 connector for LiPo power. Most LiPo batteries on the market (including ours) use a larger JST fitting. We do not yet stock batteries with an MX1.25 connector, however, you can customise your battery with one of our 1.25mm pitch cables to make a compatible battery yourself (assuming you have the ability, knowledge and tools to do this safely).
