Change of plan.
Once John really dissected the Carrera dongle and CU connection we found it needs 3.3V not 5V plus a couple of other minor anomalies.
Answer? 
First thought was to make an intermediate board to make it work or to make a specialised board? 2 boards would look like a hack job so the team decided on a new specialised board.

Unfortunately it won’t fit the MPD “one board for all concept”
though. This means more set up costs and a seperate production run and although is disappointing it’s the best way forward.

The only real alternative would have been to modify one of the data ports. But if we did that the port would only ever be suited to the dongle.
So here it is. A nRF52832 powered dongle specifically designed for Scorpius/Carrera.

The 6 rectangles on the right side is set up for a 6 pin 1.5mm socket or solder wires to these same pads, which goes to the Carrera CU via its RJ12 socket.
An LED display is not required as the controller ID is already known by looking at the Scorpius controller.

The board is powered by the 3.3V supply from the Carrera CU. Simple.

This took just 3 hours to design.

This is another critical path completed. Firmware has already been written and tested so Nitrous is almost here.
The project is finally starting to come together, and in a big way. 

Development continues.
