I have 5 of the SCfm1 design(shown in pics above) pcboard coming, thursday.
I will assemblem them, and sell them for a developer price of $35 each.
(i got a few hundred dollars out there. so ill sell these for my parts cost and no labor fees, just to get the coding going...)
this board can be used on ANY Sirius Connect, does not 100% need the SCFM1, but the FM1 has the holes in the correct place for my board. if you use a cheaper say ALP1, the cover will not go back on... or u will have to make your own holes... Id say for developing this is fine(without cover)... ALSO this directly has no connection for autos, ie wires, it uses a 1.3mm DC power jack for power... i supply the WALL Adapator (12v 300ma), in a CARPUTER u need to get own connector (or chop the supplied one) and make the connection, could use the 12v from the carputers power supply... this version does have a turn on, but its not directly exposed, its on a jumper, you could just supply 12V as accessory... there is no harm removing 12v from this unit when its off. as soon as the boards hit, ill do some final current draw tests.
again this was designed for HOME use, where a wall apdaptor is fine, and always powered is fine...
I have the New ALP1 design ready to go, that has a exposed 12V turn on.
I have to do some final checks on the board, then out to manufacturing
the pboard is costing me the most, in low quantities, and i dont know how many I will sell.. so i will prob not run more then 50
which ofcourse keeps the $ higher, but its still will be affordable
i wanted $50, but it looks like $75.
Question, is USB even inportant here? its not buss powered, so u still need power, i could save a good amount of $$ if i made it RS232, and not usb
ofcourse u need to have a rs232 port on the carputer, and im sure they are all taxed out... so maybe USB is better for carputers
remember im not a carputer guy, so i need your advice
