ESP32-S3 Development Board with 2.8 IPS Capacitive Touch Display (240 x 320)

This 2.8′ IPS touch display dev board is a great choice for those looking to create easy-to-use interfaces and experiment with different ESP32-S3 projects.

The display has a fast ESP32-S3 with an Xtensa 32-bit LX7 dual-core processor, capable of reaching speeds up to 240MHz.

The board supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) alongside 512KB SRAM and 384KB ROM, complemented by 16MB Flash and 8MB PSRAM.

The IPS display has a resolution of 240×320 and 262K colours, supporting capacitive 5-point touch control through an I2C interface.

This board is well-suited for developing human-machine interfaces (HMI) and other projects. It easily runs GUI programs such as LVGL and includes various peripheral interfaces. Included with the board are 20 x 30mm 8Ω 2W cavity speakers for audio output.

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).
