ESP32-S3 Development Board with 1.46 Round Touch Display (412 x 412)

This is a small development board powered by the ESP32-S3R8 microcontroller. With an Xtensa 32-bit LX7 dual-core processor running at up to 240 MHz, it can handle demanding tasks. It includes 512KB of SRAM, 384KB of ROM, 16MB of Flash memory, and 8MB of PSRAM, providing plenty of storage and processing power for a variety of projects.

It has a 1.46′ LCD display with a sharp and colourful 412 x 412 resolution, 16.7M colours, and a capacitive touch screen. The touch interface is controlled via I2C with an interrupt function, making it ideal for graphical interfaces and interactive designs.

Connectivity options include 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), both supported by a built-in antenna for wireless performance. A USB Type-C port provides power, programming, and debugging.

A 3.7V MX1.25 lithium battery header lets you add a rechargeable battery, and an SD card slot is included for extended storage (battery not included, see note below on the weird MX1.25 connector!).

There are two options for this board: Board only and with a protective glass case. Please choose which one you want before adding it to the cart!

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).
