Oiyagai 3pcs 433MHz RF Wireless Transmitter and Receiver Module Kit for ArduinoArmMcURaspberry pi 433MHz

Description: VCC voltage module operating voltage and good power filtering. Great influence on the antenna module reception, preferably connected to the 1/4 wavelength of the antenna, typically 50 ohm single conductor. The length of the antenna 433M is about 17cm. Antenna position has also affected the reception of the module, the installation, the antenna as possible straight away from the shield, high pressure, and interference source. Frequency used to receive, decode and oscillation resistor should match with the transmitter.
