The wireless control side of things is progressing well.

In a prototype format the system is running with frequency hopping for suppressing signal fade and the throttles using time division multiplexing to communicate with the Wireless Hub which then onward broadcasts a single multi-car packet that all cars receive.

The throttles are currently using an ATmega328u/nRF24 combination.

The Wireless Hub is currently using the same above configuration though in due course this will be upgraded to an
nRF52840 module as per the photograph below. The small co-axial socket on the module is for attachment of a back-of-box vertical oriented 2.4GHz antenna to ensure maximum range.

   

The in-car decoders as shown earlier in this thread use the ATmega328u/nRF24 combination with a more advanced version using the nRF52832. The latter has been designed in ‘saloon’ DPR-size and F1-size. Both include control of lighting circuits.

I appreciate this is, maybe, a bit too technical for some readers (and perhaps not enough for others)… anyway I hope it was worth the read.

This is a new digital slot car system in development.
