: Designed to operate on a 3.7V lithium-ion battery, with onboard micro-USB charging ports and protection circuits.
If you want, provide a high-resolution photo of both PCB sides (and any readable IC markings) and I’ll identify the main ICs and suggest concrete next steps (pinouts, firmware tools, or schematic reconstruction). Bk-m33-bt-v2.pcb
