Chose an adc/planned device
I want the console to automatically recognize each expansion module, so I will be using two resistors per module to identify them, and since I want 4 modules, that's 8 adc channels, and since I plan to use the rp2354b, which has 8 adc channels, there will be no free adc channels left for the modules them selfs, so I need an external adc. I chose the ti TI ADS131M08IPBSR, it has 8 channels, so 2 channels per module, and it's 3 USD
I chose the rp2354b because the spring uses the rp2040, so I could port the spring engine to the console
