Matek STD external Current Sensor setup

I want to run 8-12s Li-ion on wing I am building. That way I could let the volts do the work and keep the amps down on liion’s

Is it possible to use the matek std with an external current sensor? I was looking at the mauch current sensor but unsure how I would connect it(wiring?). If anyone knows where could I find the documentation for pinout to wire it up, it would be much appreciated. Also was looking at the Brain FPV PDB and was wondering if that might work for 8s on matek std (or if there is a suggestion on another fc, I prefer the mpu6000 giro).
