Circuit Description Model: ST-801 a. The U4 circuit for adjusting voltage is used for supplying enough voltage to MCU, optical sensor, and RF circuit. b. The function of MCU MA4302 is used for gathering signal produced by optical sensor or key operation and transmitting the signal to RF circuit formed by C10, L1, L3 and other electronic components to modulate, amplify and send out via antenna. c. The RF signal of 2408-2474MHz is generated by MA4302, a crystal of 12MHz as base clock signal of the MCU. Antenna Specification: Type of Antenna: PCB Antenna Frequency Range: 2400-2483.5MHz Maximum Gain: -0.21 dBi Impedance: 50 ohm Size: 16.5mm x 7.5mm Antenna View
