Review on 💼 Adafruit Trinket Lithium-Ion Lithium-Polymer Backpack by Angeline Darpino

5 stars because the board is very good in terms of size and functionality. However, I have a Trinket M0. The pinout doesn't match exactly. Looking back, I should have expected that since it was made by Pro. BUT, it actually works well. The Bat and Gnd pins correspond to M0, and the 5V sticks out of the mounting hole dead space. Connect this to USB pin M0 and everything works as intended, USB charging and power supply board when USB is disabled. Simple workaround.
