This ESP32-S3 development board has an Xtensa® 32-bit LX7 dual-core processor, which clocks up to 240MHz and has a 1.28" capacitive touch display that provides a sharp 240 x 240 resolution and supports 65K colours to provide vibrant and colourful visuals. It supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth® 5 (LE), along with a built-in antenna, providing easy integration into IoT ecosystems. The board has 512KB of SRAM and 384KB ROM, supplemented by 2MB of onboard PSRAM and an external 16MB Flash memory, offering enough space for projects and data.

Additionally, it features a USB-C connector and an onboard QMI8658 6-axis IMU, combining a 3-axis accelerometer and a 3-axis gyroscope, which are ideal for motion and gesture detection projects. A Li-ion battery recharge manager also makes it so the board can be used in portable projects.

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).
