Power Top Board

This mounts inline with squid works mother- and daughter- boards, switching (up to) 24v down to 5v.

Power Distribution Boards

I use these to distribute power through a machine. Typically I am bussing 24v from a switching power supply.

These are on a 7x24mm pitch (with 7x14mm on the TVS / Bleeder Block). The idea is to stack them pole-to-pole on a 3D Printed base, such that the screw heads connect the V+'s and GND's in a row. That 3D Printed Base can mount wherever you'd like on the rest of the machine.

One XT60 Connector (good for 60A)

XT30s

Three XT30s (good for 30A each)

Bleed Resistor and TVS Diode

I have a TVS Diode on most Mother Boards, but here is an extra, along with a bleed resistor to shunt any charge that is likely to be left over in those BFCs. Also makes me feel better about backdriving steppers.

BFC

Big Capacitors are nice to have alongside switching power supplies, in case anything draws lots-of-current-all-of-a-sudden, as is typical in motor control. Capacitance should be kept as close as possible to the circuit that sinks charge, and my motor drivers try to have some nearby, but here's more.
