The PC104 connector consists of four rows of pins labelled A-D. The PC104 standard implements an ISA bus over these headers, but we also include the ability for almost all of the pins to be used as DIO.

  1. ↑ The PC104 standard uses -5V here. If a third party device is used that might use this rail, FB17 should be removed.
  2. ↑ This is automatically controlled by the ts-pc104 driver
