Story

Can be powered with input source 14V - 50V (J3 or J4). Inputs can be configured as two independent for each half-bridge or as single input where other half is inverted (JMPR1-[3-4], JMPR2-[3-5; 4-6]).

Open Source Design.

Assembly

Download and send gerbers.zip to PCB Manufacturer. Use part list BOM and ibom.html as soldering guide.

With Interactive BOM like this no way to miss-solder.

For full power solder heatsinks to PCB from bottom side. Do not forget to put liskun isolators between MOSFETs and heatsink.
