Idea:
Expandability of next gen. CyberBrick system would IMHO be a nice feature to look forward to. The idea would be to be able to e.g. connect multiple CyberBrick units together to have more inputs and outputs.
Consider more elaborate radio transmitters/handhelds with more inputs, but also telemetry capability for models - to sample some values on the model side (e.g. battery voltage, current, light or input from other sensors) and to output something on the transmitter/handheld side (e.g. via display, LEDs, speakers, haptic).
Both above ideas could already today be achieved with combining two X11, two X12 or one X11 and one X12 shield e.g. via custom MicroPython code and communication protocol via ESP32-C3 UART0. But only two modules can be combined this way. A more plug & play solution would likely be better for general users, also based on a more expandable bus-system than point-to-point UART. For example I2C, RS-485, or CAN-bus would be some options to consider.
Who it’s for:
Advanced CyberBrick users with complex models or users who look for data feedback (telemetry) from their models.
Hardware needed:
New shields with a bus port, such as I2C, RS-485 or CAN-bus. In addition availability of Y-power harness to split power delivery into multiple shields.
