Hi!
Just bought 3 pcs FG-100 from Aliexpress and saw that they should come with Atmega328P and thought I could reprogram them, but mine came with some unmarked IC. Thought it is an Atmega chinese clone, but the pinout doesn't quite match. It only has one pin for GND and one for VCC. I marked what I managed to trace from the buttons and the programming header.
Any idea what the IC could be and how I could program it?
LE: Did a bit of searching and looks like it might be LGT8F328P, but not 100% sure yet
