[* black] The wee motherboard bears an even wee-er daughterboard layered right on top, where we find the power input connectors and a tiny biometric sensor.
[* black] With a bit of patient spudgering, the boards are disengaged—leaving the motherboard stripped and primed for some primo IC analysis:
[* red] MAX77836—likely micro-USB interface controller and Li+ battery charger
[* orange] 1513E8 E614A6
