Adding Bluetooth to Vex

On data TO the radio: I am not sure that the Vex TTL logic level 1 output would be read as a 1 by the radio input (read above)
On data FROM the radio: I am not 100% sure that the Vex TTL logic level input will like have 8V as an input

the rx and tx connections on the top of the vex controller each have 5v and ground available on the connector next to them. so connect rx-i on your bluetooth module to the pin next to the label on the rx connector, connect tx-0 on the bluetooth module to the pin next to the label on the tx connector, connect ground to the pin opposite the label on either rx or tx, and pwr to the middle pin on either rx or tx. when you get around to programming you'll be using usart2 rather than usart1 which is the programming port with the rj-12 connector on the back of the unit.
