2262/2272 4 csatornás 433Mhz Launch modul Vezeték nélküli távirányító Arduino Kit M4-hez zárolatlan vevőkártya (nincs elem)
2262/2272 4 Channel 433Mhz Launch module Wireless Remote Control For arduino Kit M4 Unlocked Receiver Board (No battery)
1.Remote control
Working voltage: DC12V (one grain of 27A/12V battery)
Working current: 10mA@12V
Radiated power: 10mw@12V
     Modulation method: ASK (amplitude modulation)
     Transmitting frequency: 315 or 433.92MHZ (sound table frequency stabilization)
     Transmission distance: 50-100M (empty ground, receiving device sensitivity is negative 100dbm)
     Encoder type: fixed code
2. With decoding receiver board
  The working voltage is DC5V and the receiving sensitivity is -98db.
  There are 7 pins, which are VT, D3, D2, D1, D0, 5V, GND.
  VT is an active signal high output pin. Once a valid signal is received, the pin outputs a high level and can also drive the relay.
  Size: 6.6*22*41mm
3. There are four buttons on the remote control, corresponding to the four data bit output pins D0, D1, D2 and D3 on the receiving board. When the button is pressed to transmit a signal, the corresponding data bit will output a high level.
