We just assembled this board, uses 4 74HC595 to control 32 AOI518 or AOI516 N-channel MOSFETs.
Will do some testing tomorrow, got some LED strips I can connect up.
Designed for 1A loads at each screw terminal from 12V supply, so something like 50 groups of 3 LEDs in series.
Each group of 8 has its own 12V connection, with Gnd for all connected.
I only had #4-40 screws & nylon standoffs to mount an Arduino. There are 4 holes for an Uno, I found this Duemilanove first tho for pictures.
We’ll selling these too, $45.25 for kits shipped to US addresses, $86.75 for assembled boards.
I only have transistors for the 1 board on hand; if you’d like a different TO-251A compatible part they can be subbed in instead.
