This board comes with an Xtensa 32-bit LX7 dual-core processor that operates up to 240MHz and 16MB Flash, 8MB PSRAM and an SD card slot. It supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) with an antenna, and you'll find UART, I2C and GPIO connections on the board with a USB-C port for power.
On the back of the board, you'll find a colourful 2.8" IPS display with 65K colours and a 480 x 640 resolution. The capacitive touchscreen version (Optional) uses the I2C connection for touch control and has the interrupt function. There is also an MX1.25 2-pin connector for a 3.7V lithium battery and an RTC battery connector.
Two variants are available - Without Touch or With Touch. Please select an option before adding it to your 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). If you want to source your own battery to fit inside the case, a battery size of 3.85 x 24 x 28 mm is recommended.
