Description and cad models given by manufacturer

bottom of board has no components and can be leveraged for heatsinking, though shouldnt be neccessary

board power dissipated as heat should scale as load current through it from battery to motors increases

requires less cooling than an ESC for sure

do not over torque through holes.

all pads are labelled with + and - are the batt + and - and are shorted together and intended for high current

solder on the pads with wires will expand board dimensions

all the tiny contacts are for low voltage signals and gnd references. Can be brought out with vertical or right angle 100mil pitch connectors or directly solderred into with wires
