Cabling; Table 8: J20 Main Power Connector Pinout - VersaLogic VL-EBX-38 Hardware Reference Manual

The table below lists the pinout for the main power connector.

Table 8: J20 Main Power Connector Pinout

Pin
1 PS_ON#
2 GND
3 GND
4 +12V
5 +3.3V
6 +VIN
7 +5VSTBY
8 +5V
9 +5V
10 -12V
11 GND
12 +VIN
Notes:
Note 1: Signal Ground must have low-impedance connection to Earth Ground somewhere in
system for safety and EMI
Note 2: The max current per pin is 6 Amps. This limits the max +5V and +VIN power to 12 Amps.
The 3 GND pins thus limits the total current to 18 Amps
Note 3: V10 jumper placement selects the voltage used for the board;V10[1:2] = 5V, V10[2:3] =
12V
Option 1 (Default)
Input Voltage
+5V ±5%
Option 2
Input Voltage
+9V - +15V
(+12V nominal)
