Hi I just took delivery of my "Pico - Uninterruptible Power Supply" and I added in the battery and connected it to a Pico, then is struck me, There are no breakout pins, most of my projects have devices connected to the pico, but if I use the UPS I can't connect any devices to it. Great idea but not very useable for me unfortunately. I will have to put it aside for now.
