This RP2040 development Board is powered by a dual-core Arm Cortex M0+ processor and can run up to 133 MHz. It also includes 264KB of SRAM and 16MB of Flash memory, providing enough space for most applications. Onboard is a lovely 1.28" capacitive touch display. This display offers a resolution of 240 x 240 pixels and can produce up to 65K colours for a clear and colourful interface. It comes in a durable CNC metal case for peace of mind whenever you are moving it around. 

With Pico C/C++, MicroPython, and Arduino IDE support, comprehensive SDK, Dev Resources and tutorials also available, you'll have everything you need for your next project. With a plethora of features and support, there are so many possibilities!

Note: The battery connector is a less-common 1.25mm pitch MX1.25 connector. You won't find many LiPo batteries with this connector fitted as standard, but 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).
