+
+### Known Issues
+V1.1
+
+1. The Drill motor controller will pull 5A but the curent power connector for the board can only handle 3A.
+2. For both RS 485 chips, the RX and TX pins need to be reversed.
+3. The RS 485 for the soil sensor is connected to the CAN RX TX instead of the Serial RX TX.
+
+V1.2
+
+No Known Issues

+This board acts as an alternate for Rover's [Tower Node](tower.md) when both of the boards we had didn't work. It really just breaks out a Teensy 3.2 to a few different connectors.
