ESP32-S3 Development Board with 2.8" IPS LCD Round Display (480 x 480)

This ESP32-S3 development board has 2.4GHz WiFi and Bluetooth BLE 5 support, it comes with high-capacity Flash and PSRAM, making it well-suited for running GUI programs like LVGL. The screen has a 480 x 480 resolution and a 160° viewing angle, providing sharp and colourful visuals from most angles.

It is driven by the Xtensa 32-bit LX7 dual-core processor with a clock speed of up to 240MHz and the board is compatible with ESP-IDF and Arduino IDE, giving you different options on the development side of things. It includes 512KB SRAM, 384KB ROM, 16MB Flash, and 8MB PSRAM.

The board supports multiple peripherals via GPIO, UART, and I2C connections, and includes a USB Type-C port for power, programming, and debugging. There is also a QMI8658 6-axis sensor, an RTC sensor, an SD card slot, and a battery recharge manager to give you a lot more options 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).

Two variants are available - Without Touch and With Touch. Please select an option before adding it to your cart!
