Existing Android boards having 3G, WIFI, Bluetooth, GPS, Camera. But I want to build extra hardware support for Fingerprint Scanner, RFID Scanner, Thermal printer on board itself. Power supply with different slot & also support usb debugging function with PC. I am ready to pay for it, if this you design the schematic and pcb layout.
Thread closed as it isn't going to go anywhere useful
I don't think the OP has any idea about the complexity of what he is suggesting
and it definitely isn't for a hobby electronics forum
