I just started developing for Maduino with Arduino IDE. Everything works fine until now. There is just one thing to improve - please connect Ring-Pin (10) of SIM module with a free GPIO of SAMD for future releases in order to let the SAMD sleep until a SMS or Call is coming. With Ring Pin connected I would give a 5 star rate and I would order additional Maduinos.
When re-searching how this has been done, the levitation's as intersting (and practical) as the method. 'Makerfabs' , an experiment, working from Shenzen for outsourcing,globally, at a free-lancer level... And the results? yep, they've done it. Now who's going to be cleaver enough to use it? The biggest risk after sales, propotionate overheads, seeing as the service user can assume they did everything they should have, on all count counts... what a ak cent on vampire guy? he d therves an cuv ant....hypno-tique!
