Jumpers
Definitions:
Sel – Select
Tx – Tank Transmit
Rx – Tank Receive
PGM – Program
Vin – Input Power
PSel – Power Selection
J4 – Jumper 4
J5 – Jumper 5
J6 – Jumper 6

– If J4 has Rx selected (like the picture below), than the TankShields Rx matches Arduino pin 13. In the PGM position Rx matches Arduino pin 1.

– If J5 has Tx selected (like the picture below), than the TankShields Tx matches Arduino pin 12. In the PGM position Tx matches Arduino pin 0.



– The TankShield motors can receive power from Vin or 5V depending on the J6.
