“This is a brilliant little widget that turns a Pico or Pico W into a properly mobile-ready device. A few quick solder joints and you've got a device that'll look after it's own state of charge, managing the battery, switching to mains if it's available and what's more it includes a power on/off switch worth the cost of admission alone.”
“Great idea to keep the Pico running on LiPo batteries with quick connect for the battery you can swap them out once charged or keep the battery connected as it auto cuts out once full. Like the little power button too which is well positioned for an enclosure.”
