Description: Stable performance; Wide operating voltage range; Good product consistency and high cost performance; The on-board coding chip is easy to use.
Technical parameter:
Working voltage: DC3-9V
Working frequency: 315MHz/433MHZ (optional)
Standby current: 0mA
Working current: 15mA
Coding method: Fixed code
Transmission distance: >500m (opening board sensitivity is above -103dBm)
Output power: 15dBm (32mW)
Transmission rate: <10Kbps Modulation method: OOK (amplitude modulation) Working temperature: -10°C~+70°C Size: 36 × 23 × 8mm PIN NAME Function 1 13 Data pin 2 12 Data pin 3 11 Data pin 4 10 Data pin 5 VCC Power + 6 GND Power - 7 ANT Antenna end Precautions for use:
1. Use a flexible wire or other hard metal (such as a whip antenna) for the antenna to a length of approximately 28 cm (315 MHz) / 24cm (433MHz) and use it as straight as possible. Do not approach metal objects.
2. The power supply voltage is stable and the ripple factor is low. Multi-stage filtering is required (such as adding beads, inductors, capacitors, etc. ).
3. If the MCU clock frequency is below 4MHZ and the crystal is as far away as possible from the RF receiver module, the higher harmonics of the crystal will affect the communication distance.
4. Note that the rate of the encoding IC and the decoding IC is the same and the format of the code is the same (that is, the oscillating resistance is matched), otherwise the distance will be affected and the communication will not be possible.
Package includes: 1 x Receiving Board
