“Just as I was messing about with modifying a LiPo charger to fit my tiny portable project, this came along and made my day.
Very easy to use - on/off button along with charging indicators works just like you'd expect.
Just make sure you get an appropriate LiPo battery for the 215mAh charge rating.
My project consisted of a Pico + LiPo shim (soldered to the short side of the headers as per one of the suggestions in the product description) and a Pico Display, with a 210mAh LiPo battery sandwiched in-between (I found the perfect size of battery of 35 x 14 x 5 mm). I had to tear off the battery connector on the LiPo shim board to get the battery to fit in between the shim and the display, which was easy enough to do with a pair of pliers. The result was a super compact, portable, finger-sized display with a pico, with about ~3 hours of life on a single charge. Great for a tiny games console!”
