This RP2040-based round LCD board from Waveshare includes a truck-load of features crammed into a neat, compact package - the powerful RP2040, a quality round IPS LCD, accelerometer, gyroscope, lithium battery support, BOOT/RESET buttons, USB-C programming/power and GPIO pin access!

We think this is going to be a great board for lots of different projects, from wearable badges to embedded device displays and everything in between.

The round LCD is a 1.28" 240x240 IPS panel offering 65K colours for clear images, text and data. Programming is available via a robust USB-C connection, with access to plenty of the RP2040's GPIO pins via the rear 1.27mm pitch pin header. RESET and BOOT buttons are also onboard for your convenience.

Power is achieved via the USB-C connection or the onboard MX1.25 lithium battery header, which includes recharging for lithium batteries via the USB-C port (allows power and battery recharge at the same time).

The onboard QMI8658C 6D MEMS IMU offers a 3-axis gyroscope and a 3-axis accelerometer to include orientation and movement tracking in your project.

The product Wiki includes some limited demo code, datasheets and a clock project example to get you started.

Please 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).
