A new version PCB and Gerbers has been released on the
Ukrainian forum.
Basically they:
Fixed some PCB polarity errors (C26);
Replaced C10 with .1uF;
Replaced R9 with inductor 4.7uF, now called DR7;
Added connection for DHT temp humidity sensor, pin 13 of ATMega328P. Connected to Vcc via new R9 (10k) on bottom of PCB;
Added suitable quick connect connectors for USB and +12V/Gnd inputs.
I'll go over these changes and change our PCB respectively. The SIL for the connector for the power could be an issue. Those 2.54mm connectors are only rated to ~2.5A ...I reckon even less. Jaycar has .156 (4mm) connectors rated to 7A...these might be a better bet. I'll see if I can get them to fit.
EDIT:
Ok got the USB 3 pin SIL on the PCB. I can get the .156" 2way SIL but I'll have some small movements, and I'll look on fleabay/RS to see if I can get a slightly small body version than Jaycar's. I have connectors similar to those used in their PCB but no 3way versions or .156" version.
