HelloPenguin is too cool
For HelloPenguin
Great bright LED animations in a cute penguin shaped pin. Sure to be fun around the holidays. Ran into an issue with it freezing with off brand batteries, likely due to current draw and battery's internal resistance. So use high quality batteries! Good news is that the maker was very helpful in diagnosing the issue and with SWD port and GitHub repository software updates and customization should be easy.
