Product Number: ADXL355
I have ADXL355B on my PCB board, which so far I have a vendor make 2 batches.
For the first batch of PCB boards, my firmware to configure ADXL355B and read x, y, z, and temperature values has been working fine for a very long time, more than one year already.
Recently I asked vendor to make a new batch, with exactly the same design. This time the acc reading becomes much smaller, roughly 5 times, while the temperature reading is still correct.
- Hardware the same design
- Firmware the same code.
The only difference is the ADXL355B batch number.
- The 1st batch number is 2047106639
- 2nd batch number is 2251615397
Anyone has any idea what happened here?
