The communication between the electronics within the solar boat is build upon the CAN-bus protocol, where the datalogger logs the CAN messages. Pinout of our Binder connectors are:
- Brown VCC (24 V)
- White CAN H
- Blue CAN L
- Black GND
- Safety
Battery (MG) CAN-format (No longer used)
As of now the MG electronics battery is used in the solar boat. Although a new battery is being developed, this MG battery is still in use (as of September '22). Therefore the battery format is given here below.
