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.
