### Soldering the electronics
1. Solder on two rows of 8 male pin headers to the D1 mini

2. Solder on two rows of 8 female pin headers to the battery shield
3. 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.
- Note:
3. Connect the + pin of the connector from the battery shield to the + pin of the motor 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.
After this is done, repeat the same with the - connection. Please make sure that you do not reverse the polarity!
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:

*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*
|First, solder two wires to the + and - pins of the battery shield and isolate them with heat shrink: |
|--------------|---------------|
|Cut two small pieces of wire (about 4 cm), remove the isolation on both ends and cover them with a bit of solder | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_batter_stack_2.jpeg)|
|Solder the first wire to the + pin of the battery shield | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_3.jpeg) |
| Solder the second wire to the - pin | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_4.jpeg) |
| Cover both wires with small pieces of heat shrink tube | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_5.jpeg) |
| Heat the shrink tube with a lighter | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_6.jpeg) |
| This is how the battery shield should look like with the two wires | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_6.5.jpeg) |
|Next, we create a connector for the female JST 2-Pin connector for pluggin in the battery: | |
|--------------|---------------|
| Cut two small pieces of wire (about 3 cm), remove the isolation on both ends and cover them with a bit of solder | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_7.jpeg) |
| Solder the first wire to the JST connector |![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_8.jpeg) |
| Solder the second wire to the JST connector | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_9.jpeg) |
| Cover both wires with heat shrink | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_10.jpeg) |
| Solder the wires to the motor shield, paying attention to the polarity *(make sure it matches the polarity of your batteries!)* | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_11.jpeg) |
| Now, stack the battery shield on top of the motor shield and solder the | |

| This is how it should look like in the end. Make sure all of the exposed wires are covered in heat shrink | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_12.jpeg) ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_14.jpeg) |
| Now you can stack the D1 mini ontop of the battery shield | ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_battery_stack_13.jpeg) |
| Now it is time to connect the D1 mini to your computer | |
