To drive LEDs or low voltage lamps up to 2.5 amps, 10 amps with a heatsink.

Empower your arpschuino! (2 or 32)!

The outputs of the apschuino² and arpschuino32 can only supply an intensity limited to a few tens of milliamperes. It is enough for turn on small signal LEDs, but for powerful LEDs, low voltage lamps, motors or electromagnets, you will need more power.

With the arpower, the arpschuino is able to drive powers up to 2.5 amps, and even up to 10 amps with our heatsink kit

Since the R4 version, the heatsink kit has been redesigned to be more compact, easier to assemble and for better heat dissipation.

You can connect two arpowers per arpschuino, using ribbon cables. See above how to connect your devices to the arpower.

It is perfectly possible to connect different types of equipment, even working at different voltages on the same arpower.

The arpower kit is to assemble yourself. We can do the work for you, on request.

 versions :

R4 news:

Completely redesigned circuit board to improve heat dissipation.

Mounting without heatsink: mounting the mosfets flat with the IC which optimizes and improves heat dissipation.

Mounting with heatsink: Flat heatsink for better compactness + fixing lugs. Easier assembly.

R3 news:

New numbering of entries corresponding to arpschuino ports.

R2 news:

New PCB, nicer, same specifications.

Flat connectors.

The fixing holes have been enlarged for the use of M3 screws..

Serigraphy more usable on each side.
