| Radio Controlled (RC) / Bridged |
Both motors on the left side are wired to one channel of the Sabertooth motor controller, while both motors on the right side are wired to the other. This ensures motors on the same side receive the same signal ("skid steering"). The Sabertooth's onboard BEC powers the RC receiver. Not Connected

| Microcontroller / Bridged |
Both motors on the left side are wired to one channel of the Sabertooth motor controller, while both motors on the right side are wired to the other. This ensures motors on the same side receive the same signal ("skid steering"). Optional Connections

| Microcontroller / Independent |
Two dial channel Sabertooths are needed because motor is connected to its own channel and can be controlled independently. Normally the encoders are connected to the microcontroller to measure angular speed and estimate distance traveled. Connections depend on the microcontroller chosen. | |
