Output Devices

In a prior week I produced 2 pwm small motor drive circuits so this week I experimented with 2 layer PCBs using the vinyl cutter. I produced standard and a modified LED array boards.

For this weeks project I modified and produced the hello.44.array board to interface with the FabKit board.

Standard vinyl hello.array.44.2 board
