Product Information
super regenerative wireless transceiver/remote control module
Model Number: M2021020
The super regenerative transmitting module adopts ook amplitude modulation, which has good product consistency and high cost performance. The transmitter adopts saw to vibrate, with stable frequency and small temperature drift. However, when the ambient temperature changes between – 25 ℃ – + 85 ℃, the frequency drift is only 3ppm / ℃, which is especially suitable for multi transmitter and one receiver remote control and data transmission system. The transmitting module can be used with the same frequency receiving module of fixed code and learning code in the market, or with the wireless receiving module of our store. The product can only be used after secondary development and decoding with single chip microcomputer or 2272 chip.
The super regeneration receiving module adopts LC oscillation circuit, including amplification and shaping. The output data signal is TTL level and ook amplitude modulation, which can be directly connected to the decoder. Good consistency of product quality and high cost performance. At present, it is a high-frequency receiving module widely used in the wireless remote control market, which can be used with the same frequency remote controller with fixed code and learning code in the market. The receiving module has a wide receiving bandwidth, generally ± 10MHz. 5V DC power supply is generally adopted, and the adjustable voltage is 3-8v under special circumstances. The static working current of the receiving module is generally 4mA when leaving the factory. Under special circumstances, the current can be reduced. The minimum current can be adjusted to 1.5mA, but the receiving sensitivity will be reduced. When leaving the factory, the output of the receiving module is noise output. Under special circumstances, it can be changed to noise free output, but the sensitivity is reduced.
5V super regenerative receiving module
Working voltage: DC5V, working frequency: 315MHz / 433MHz, static current: 4mA, receiving sensitivity (DVM): – 105dB, transmission rate: < 10kbps, modulation mode: amplitude modulation (ask), working temperature: – 10 ℃ – + 70 ℃, size: 30 * 14 * 7mm
Transmission distance: it can be used directly without shielding (without antenna), and can reach about 50m in open areas without electromagnetic interference; If it is shielded, it is best to add an antenna of about 17cm. As long as the copper wire is not too thin, the effect is not so obvious.
Without coded transmitting module
Model: mx-f01, working voltage: 3-12v / 433MHz, working frequency: 315MHz, standby current: 0ma, working current: 20-28ma, transmission distance: 10m-200m, output power: 16dbm (40mW), transmission rate: < 10kbps, modulation mode: 00k (amplitude modulation), working temperature: – 10-70 ℃, size: 19 * 19 * 8mm
Product Parameters
ANT: connected to antenna terminal, ACC: positive pole of power supply, DATA: data output, GND: negative pole of power supply
Tip
If the distance requirement is far, a 1 / 4 wavelength antenna can be connected. Generally, 50 Ω single core wire is used. The antenna length of 315MHz wireless receiving module is about 23cm and that of 433MHz wireless receiving module is about 17cm. The antenna position also affects the receiving effect. The antenna shall be installed as straight as possible and away from the shield, high voltage and interference source. When in use, the receiving frequency, decoding mode and oscillation resistance shall match the transmission.
