Nie jestem pewien czy w dobrym miejscu ale spróbuje....
Ostatnio realizuje projekt ze strony http://www.embedtronics.com/nokia/fbus.html
i mam mały kłopot bo nie zabardzo wiem o co chodzi z zasilaniem nokii wg tej strony
"Now we know how all this works, the best way to connect an external supply is to get an old Nokia battery and disassemble it. Then just connect your power supply on the B+ and B- pins, the rest is done for you. If you have ever worked with embedded GSM modems, you will be aware of the high peak currents involved when the phone is transmitting. Your power supply must be able to supply the current required by the phone with very little voltage drop. A regulator of 2Amps should be enough. Therefore keep your wiring very short, even better place the regulator in the battery holder and have very good, low ESR Tantalum capacitors near by. This is not for the beginner!"
i tu moje pytanie do tych kondensatorów tantanowych jak duze maja byc i czy muszą być ??
