V. Application Environment
Wireless remote control, data transmission, remote control toys, burglar alarm host; Industrial remote control, telemetry, remote sensing; Burglar alarm signal is received, the remote control and other various household appliances.

Seven, notes

Antenna with a soft wire or other hard metal (like telescopic antenna), the length of neither too long nor too short (preferably connected to 1/4 wavelength antenna, 50 ohm single-core wire, the length of the antenna is about 315M of 23cm, 433M of about 17cm), otherwise it will affect the receiving distance. If you use soft wire, please straighten use, and try not to close metal objects.

Supply voltage for stability and low ripple factor, to be multi-stage filter (such as increasing the bead capacitors, inductors).
