More of a good thing….if the 14M2 can’t offer you enough I/O, the 20M2 must surely be getting close!
This is the motherboard:
The good news is that all PIGGYMIDDLE daughter-boards are pin compatible with this one, with the added benefit of leaving 3 spare I/Os at the bottom of each column. It would be a simple task to wire up a second daughter-board of some sort, or even go for a 3 layer ‘stacked’ concept.
And here is an application showing what can be done – a woolly glove with some clever sensors sewn onto the back and wired as simple potential dividers, the outputs from which feed 5 ADCs in the Picaxe.
As usual, suggestions are welcome! By all means email
