## Assembly instructions
|
|
|
|
#### Robot chassis
|
|
Assemble the chassis according to the instructions provided by adafruit ([see here](https://learn.adafruit.com/tri-layer-mini-round-robot-chassis-kit)).
|
|
|
|
### 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!
