4 channel 5V Relay shield extension board xbee Relay Shield V1.3 for arduino compatible


External supply voltage: 7 ~ 12 V (> 200 mA)
Maximum switching voltage relay: 240VAC / 30VDC
Maximum switching current of relay: 3A
Relay: 4
Wireless output interface: (serial) xbee / Bluetooth Bee / wireless programming module
The rotating light has two threads from the bottom for fixing with screws (enclosed)
The cable is compatible with typical servo wires. Via +5V (red) and - (brown) the module is controlled
Via the signal line (orange) the signal mode (flashing sequence) is changed. A change of mode is initiated when a PWM signal (from the RC receiver or a PWM signal from the microcontroller) is changed via the signal line (yellow)
To change the mode, the PWM signal must fall below approx. 30% (pulse duration) and then exceed approx. 60%
Possible modes: rotation, fast rotation, slow rotation, flashing, fast flashing
