During the past weeks we have almost completed our overhaul of the boats electronic systems. We had a custom PCB made to manage all of the sensor and control signals supplied to the Arduino unit. The following shows the control board with supporting electronic “breakout” shields attached.
The idea is to make everything modular. Note the JST connectors on the left, each one roughly corresponds to one connector on the side of the electronics box. This way, removing things from the box does not require complicated re-wiring of existing components. This next picture shows the current contents of the electronics box.
Right now the box is very messy, and needs some more work before it can be cleaned up. A design revision of the control board is needed to accommodate an additional chip due to some changes we made to the overall design of the electronics. For now however, the entire thing is completely functional and still pretty modular, removing components is not a difficult task.
One major feature that has been added, are the connectors on the side of the box. These are waterproof industrial connectors with a solid latching mechanism that should prevent them from ever unintentionally coming undone.
