There was a suggestion to remove a component to allow the M2 to read the voltage of the 12 volt supply. Apparently there was something added as protection that wasn’t actually needed that prevents the reading of the voltage of the system.
Would be nice if that were removed or changed in a manner to allow the voltage to be read up to normal “running” voltage.
Also on the break out board, although not directly related, can you provide these with a header already soldered on? would be much easier to connect other devices to it if it came with a header presoldered on the board. if people want to still solder something onto it they can onto the bottom of the pins.
There was also a request for support for a battery connection to allow for a RTC. While installing a full battery onboard may be impractical perhaps having a connector where one could be connected would be reasonable.
I just heard from someone about a request for a hopefully simple modification.
In Australia they still have ALDL equipped vehicles which is on pin #9. Should be easily to duplicate on the M2. Would require one of the 12 volt outputs and a 12volt input to be connected in parallel to the pin. Just not sure yet if it would be sink or source. It could be made an optional addition by just adding a couple traces and a solder pad. Would allow easy adding the port if necessary. So the circuit would be open if no solder. If solder then it would tie the 12volt input, 12volt output and pin #9 together. Currently pin 9 is a test point.
Other than onboard fuses that can be easily replaced on the Input/Output section those are the only things that come to my mind.
