The extension board with integrated switches, single LEDs, and 7-seg LEDs support the use of Arty Z7 FPGA.

General specs:

• Eight switches with LEDs indicating logic level, isolated from the Arty Z7.
• Four single LEDs indicating the logic level.
• Four 7-segment LEDs are driven by CD74HC4511 BCD-to-7 Segment Latch/Decoder/Drivers.
• All LEDs are driven by BJTs to control drive current from the logic pin is 5uA and the supply current to drive LEDs is 5mA.
