Programming card quick guide

Jumper port function
Power jumper covers various situations of power source for target(receivers) and Programming card
when target is connected via UART port of Programming card.
Jumper 1-2
When pins 1-2 are shortened by jumper, VCC target line of P2 (UART connector, pin 4) is connected to
VCC 5 volt regulator of the Program Card.
In this position:
- Programming card can be powered by external device (receiver connected via UART connector) if
target is powered externally and provides power to the UART connector pin 4. Please make sure that the
voltage provided is not more than 5VDC.
in this case programming card should NOT be powered via USB or external power connector.
- Target can be powered via Program card UART connector.
If Programming Card is powered via power connector (7.5~18.0 VDC) then program card will provide 5V
DC on UART connector Pin 4 with jumper in position 1-2.
In this case please make sure that target is not connected to any external power source (ESC or BEC)
