Product parameters:
Working voltage (v): dc5v
Static current (ma): 4ma
Mode of modulation: amplitude (ok)
Working temperature:-10°C~+ 70°C
Reception sensitivity (dbm):-105db
Frequency of work (mhz): 315,433.92 mhz (266-433mhz frequency segment optional)
Size (lwh): 30x14 x 7mm
Product characteristics:
The super-regenerative receiving module uses lc oscillator circuit, which contains amplification and shaping, and the output data signal is ttl level, can be used directly to decoder, is very convenient and inexpensive, so it is widely used.Small size and high sensitivity of products;Easy debugging of frequency points and short supply cycle;High quality consistency and cost-effective, is the most widely used hf receiver module in wireless remote control market. the receiving module has a wide reception bandwidth, usually 10 mhz, and is usually transferred to 315 mhz or 433.92 mhz when out of factory.(If special requirements exist, the frequency range is 266 mhz~433 mhz.)。The receiving module is usually dc 5 v-powered and the voltage can be adjusted with special requirements. the voltage range is 3~8 v.
The static working current of the receiving module is 4 ma when it is out of factory. if special requirements exist, the minimum current can be adjusted to 1.5 ma, but the receiving sensitivity will be reduced.The output of the receiving module is noise-free when out of the factory. if there is special requirement, it can be changed to noise-free output, but the receiving sensitivity will decrease.
Ant antenna terminal, vcc power positive pole, data output, gnd power negative pole
The receiving module has four external interfaces, which are represented in english. Vcc represents the positive electrode of the power supply, data the output, and gnd the negative pole of the power supply.
Antennas of 50 ohm 1/4 wavelengths should be attached before use and should be straight to achieve optimal reception, wavelength light speed/freq
