Hey! New year.
I bought a lot of 5 chips, BD92001 5121, and after instaling them on 2 JDM-001 boards they show the same signs of "malfunction" so to say. Both turn on with bluetooth connection, but both refuse charge with only around 50ma going in, don't show lights and don't accept USB data. The daughter board is a known working one.
Both boards are 1-889-300-11
Please, what am I missing?
