Pi PICO in Pimoroni Breakout Garden Base
RV3028 RTC Breakout
1.54" SPI Color Square LCD (240x240) Breakout
BME280 Breakout - Temperature, Pressure, Humidity Sensor
That is a work in progress.
Pi PICO in Pimoroni Pico Omnibus (Dual Expander)
Pimoroni Pico Display Pack
That is a work in progress.
Pi Pico in Pimoroni Pico RGB Keypad Base
That is a work in progress.
And several others plugged into solderless breadboards etc I have tinkered with.
The RGB Keyboard base I got from you (Jack) will end up being a USB Hid keyboard. The buttons will launch / open stuff when pressed. Mostly taskbar shortcuts to open my Pi camera video feeds. Button 1 will launch Camera one web browser feed etc. That's likely the first project to actually see completion. It will be like the Pimororni Keybow, just a lot cheaper.
Next after that I think will be getting the PICO Breakout Garden setup doing something useful.
