Current issues:

Basically, the current PCB works great but there are several flaws found:

  1. MPU9250 is used but it works in DMP mode only: no magnetometer in use. Consider migrating to MPU6500.
  2. MEMS work in SPI mode - better use I2C: easier routing, less register access issues.
  3. J1850 interface uses MCZ3999 which doesn't work with 3.3V logic at all. Should use a basic NPN-based modem.
  4. Use linear PSU, no need for fancy PWM PSU that introduces a lot of noise.
  5. Introduce some kind of connectors
  6. Move SWD pins to the edge of the board.
