Important Notes
• For the basic version (tracks), assemble the Tamiya Twin Motor Gearbox in the Type C configuration
ONLY. Note that Type A and Type B configurations will cause the track to be too tight. Note that some
parts will remain unused.
• If you use the crimps, the bare motors leads closest to the board can potentially contact the pins on the
underside of the PCB. We highly suggest covering the pins closest to the motor leads with a bit of
electrical tape, and also wrapping the bare leads of the motor with electrical tape (not included with
the kit)
• Use EITHER the mini JST connector (15) or the Barrel connector (16). NOT BOTH.
• The pair of Xbee headers included in the kit need to be soldered to the board in Xbee slot 2.
• Bluetoth pairing code is 1234 (used to be 0000). Refer to the Bluetooth module datasheet to be certain.
Power
The Bluetooth and Xbee kits include a 3.7V, 1000mAh LiPo battery pack which was chosen because the
standard Tamiya motors operate at ~3V nominal. The board (microcontroller and motor controller) will only
turn on if you set the On/Off switch to ON. The batteries connect directly to the motors (not regulated). The
mini JST can handle up to ~12V, but keep in mind that the voltage goes directly to whichever motors are
connected. Use EITHER the mini JST connector OR the barrel connector – NOT BOTH.
The DFRobotShop Rover Bluetooth and Xbee kits still include a 4xAA battery pack which can be connected
directly to the white power input at the back of the board instead of the LiPo . Both alkaline (1.5V) and
rechargeable (1.2) batteries can be used, and the batteries power both the board and the motors. Remove
jumper (1) in figure 1 when using the AA battery pack.
