Power Connections
1. Connect an external 5V to pin 1 or 2 of JP5, on Deserializer board. (Refer
2. Connect ground to pin 3 or 4 of JP5, on Deserializer board. (Refer
3. Optionally, these boards can be configured for 12V supply via Power Jack, JP11 on both the boards
separately. However, this would require U21, TPS65320 to be mounted on Deserializer board, as it is
