I giving a way 2 of this nice 10 relay boards. Salvaged from working a control system to be discarted.
They are 12 vdc coils drived by 2 ULN2004, also have indicator power led and filter in the OUTs.
The board measures about 3.25 x 4.0 inches.
I hope that 2 of you people can use them.
Update------- They are SPST, one make by relay.
