This ESP32-S3 Development Board has a 32-bit LX7 dual-core processor, making complex and demanding tasks a lot easier. It integrates a GC9A01 display driver chip, which is made to handle graphics and display-related tasks. It comes with a 1.28" IPS round LCD, providing a compact yet clear display, and the screen's IPS technology ensures wide viewing angles and vibrant colours. Speaking of colours, the LCD supports 65K colours and has a resolution of 240 x 240 pixels for rich and vivid graphics and text.

When it comes to motion detection and gesture control, this board has you covered with a QMI8658 6-axis IMU. This includes a 3-axis accelerometer and a 3-axis gyroscope, providing accurate and responsive motion-sensing capabilities.

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).
