Layout for rev 0.2 is complete, it’s PCBtrain time again. I should get the boards before the bank holiday season starts next week.
Key changes to rev 0.2:
- Improved voltage and current monitoring on the isolated side
- Fixed Atmega PWM pin.
- Improved filtering on voltage rails – there is space for play here, with an excessive number of cap footprints.
- Different inductor – higher peak current, smaller package, lower price. Also lower isolation.
- Size is now 75mm x 50mm (was 60mm x 50mm)
