Accelerometer replacement - brb78 - 02-07-2023
Seems my accelerometer has died. Has anyone successfully replaced this part that cares to share?
Pine has a datasheet available for the BMA421 (although some post indicate this part may have been changed, my PT is from 10/21)

AliExpress seems to have them available for $6.50 shipped, and I'm willing to attempt a repair

Although its tempting to just replace the whole unit for under $40 shipped, I'd be more interested in that route if I knew when it failed again I could replace that part.
