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

This ESP32-S3 1.69" LCD has a display with a 240 x 280 resolution and 262K colour for sharp and vibrant visuals. It is equipped with an ESP32-S3R8 Xtensa® 32-bit LX7 dual-core processor, running at up to 240MHz main frequency. The board supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth® 5 (LE) with an onboard antenna for seamless connectivity.

We are now stocking the updated version (as of 23/04/2025), which has a change to the pinout. Please see the Wiki for more information.

It includes 512KB of SRAM and 384KB of ROM, alongside 8MB of onboard PSRAM and an additional 16MB of external Flash memory. The USB-C connector provides an easy connection, and there is a built-in ST7789V2 display driver and CST816T capacitive touch chip, which utilise SPI and I2C communication, respectively, to conserve IO resources. Additionally, the board has a QMI8658 6-axis IMU, which includes a 3-axis accelerometer and 3-axis gyroscope, capable of detecting motion gestures and counting steps. It also comes with an onboard 3.7V MX1.25 lithium battery recharge/discharge header, making it a great choice for your next project!

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).
