| 22 | There will be (7) sites for plug-in Analog or PWM boards. |
| 23 | Each plug-in module will have two 25-pin headers with pinout given below. |
| 24 | In addition there are two 10-pin headers on the PWM boards to supply 24V power. |

| 53 | There will be four sites for ARM processor modules (SparkFun SAM D21 mini breakout) |
| 54 | with 24 pins each. Wiring to the analog/PWM sites will be as shown in the block diagram. |
| 55 | Below is the pin wiring for the processor sites. Note that the odd numbering matches |
| 56 | that on the SparkFun schematic. |
