This development board uses the ESP32-S3R8 chip and has dual-core Xtensa 32-bit LX7 processors running at up to 240 MHz.

A colourful and vibrant 1.43″ AMOLED display sits on top of the board with a QSPI (Quad serial peripheral interface) with a 466 x 466 resolution, 16.7 million colours, and a 178 wide viewing angle. It has capacitive touch through the I2C interface, with interrupt capabilities.

It supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) with an antenna and lets you switch to an external antenna by resoldering a resistor for more flexibility. A USB Type-C port is included for power, programming, and debugging. There are reserved headers for USB, UART, I2C, and GPIO that allow you to expand your project by adding additional modules and devices.

The board also has an RTC chip, QMI8658 6-axis IMU (with a 3-axis accelerometer and 3-axis gyroscope for gesture detection and step counting), an SD card slot, and a 3.7V MX1.25 lithium battery header to use on the go!

Two variants are available – the board only, or with a CNC Metal Case.Please select an option before adding it to your cart!

Please note: this board uses a tinyMX1.25connector 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 withone of our 1.25mm pitch cablesto make a compatible battery yourself (assuming you have the ability, knowledge and tools to do this safely).
