Product title : 433M 4Ch RF Wireless Remote Control Switch Relay Board  for Arduino UNO MEGA2560
 
 
 
Packing list:
1  PCS DC5V 4 Channel Arduino Relay Board;
1 PCS 433M 4 Buttons Remote (This remote doesnot have a battery inside，Battery 12V 27A )
1 PCS 433M 4 Channel Receiver module 
 
Description:
 
This is based on ARDUINO UNO/MEGA2560 433M Wireless Controller Kit , include ：
4 Channel Relay Module,4 Buttons Remote,4 Channel Receiver module.
Easy diy you ARDUINO wireless controller(Assuming you already have ARDUINO UNO/MEGA2560) ,Very interesting!
 
NOTE :Does not include ARDUINO UNO R3!  
 
DC5V 4CH Arduino Relay Board: 
5V 4-Channel Relay interface board, and each one needs 15-20mA Driver Current
  
Indication LED’s for Relay output status
  
Only use Arduino 4 Digital IO: A0 A1 A2 A3;
  
Can be inserted directly into Arduino uno mega2560,Ideal for linking up to your  Arduino UNO Mini Nano Mega2560 etc,or others MCU ( AVR STM32 ARM PIC AT89C51 STC MSP430 FPGA CPLD etc.) 
 
4 Channel Relay Board Size : 75mm*55mm*19.3mm
 
 
 
 
 
 
 note:Packing list does not include ARDUINO UNO R3! 
 
 
433M 4 Buttons Remote:
 
Power supply : 12V 27A battery  replacable .(This remote doesnot have a battery , Please buy in your local market ))
