Hi everyone,
I plan to built 3 picstep controller, the interface output board and the daughter input board.
I have problem with part list for the interfaces board. There are no value for the TBA resistor.
Are these special resistors ? Maybe TBA is a abbreviation ?
I've attached schematic for the output board.
Thank you for your help !
