Schematic
- Schematic
Note for FM1310
- C4(0.1UF) has to be close to IC pin 9
- Y1(32.768KHz crystal) has to be close to IC pin 16
- Place an GNDRF parallel next to the RFIN(pin 13) trace, and try to make sure they are the same length.
- L2/L1/L3(Bead) must stay close to the ear bug socket.
- Volumn and seek switch must have separated 100K resistor, can't share this.
