RP2350 Development Board with 1.69 Capacitive Touch Display (240×280)

This RP2350 board has a dual-core Arm Cortex-M33 and Hazard3 RISC-V processor that operates up to 150MHz. It has 16MB Flash, 520KB PSRAM, and an SD card slot. The board also has a 6-axis IMU with a 3-axis gyroscope, a 3-axis accelerometer and there’s a USB-C connector for power and programming.

On the back of the board, you’ll find a colourful 1.69′ capacitive touch display with 65K colours and a 240 x 280 resolution that the ST7789T3 display driver powers. You’ll also find an MX1.25 3.7V Lithium battery charger and an RTC battery header. There is plenty of support for Pico C/C++ SDK, MicroPython and Arduino IDE with resources and tutorials to help you get started!

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.
