Schematic for v2.0

 

Schematic for v1.2

LED1, R1, R2 and R3 are optional, not included in the kit, and should be installed only if the user wants the "Low Battery Indication" function. Check the MAX756 datasheet for information on how to pick R1 and R2.

R5 should be installed as either a pulldown or pullup (like R4) - in the V1.2 pcb there are two positions possible
