Recently purchased a Pico RGB Keypad Base - Pimoroni from my local MicroCenter.
Soldered headers onto a fresh Pico W, installed the pimoroni Pico-W uf2 firmware and tried the demo.py code.
All buttons respond to being pressed but buttons E and F do not light up.
I know all buttons respond to being pressed, because I have to press both E and F to get one color cycle to complete and move onto the next one.
The module uses I2C, so I don’t think it’s the soldering job or the connections.
Is this a hardware ( 4x4 pad ) issue?
What can I do to get it working fully?
