Solder on two rows of 8 female pin headers to the motor shield as well as a single row of bent pins. Make sure they are soldered on the right way around.
4. In addition solder a jumper to the motor shield to connect the RTS and 3V pin. This will become important later on. Also solder the I2C bridge. 4. In addition solder a jumper to the motor shield to connect the RTS and 3V pin. This will become important later on. Also solder the I2C bridge.
- Note: 3. In the next step we connect the battery connector pins of the battery shield to the + and - pins of the motor shield. In addition we will add a connector to the motor shield where we can plug in the battery. Here is a schematic:
3. Connect the + pin of the connector from the battery shield to the + pin of the motor shield. ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_bb.jpg)
*Note: I added a new connector instead of using the one already on the battery shield because the plug of my battery wouldn't fit in the on on the shield*
For this cut some small piece of wire and remove the isolation on both ends. then twist the ends and put some solder on both ends. Cut a piece of isolation and wrap it around the wire. Make sure you do this before soldering on the second end of the wire. |First, solder two wires to the + and - pins of the battery shield and isolate them with heat shrink: |
After this is done, repeat the same with the - connection. Please make sure that you do not reverse the polarity! |--------------|---------------|
