low operating voltage: 1.9 ~~ 3.6V low-voltage.
high-rate: 2Mbps, air transmission time is very short, greatly reducing the wireless transmission of collision phenomena (software settings 1Mbps or 2Mbps air transmission rate).
Multi-frequency points: 125 frequency points, to meet the multi-point communications and frequency hopping communications needs.
ultra-compact: built-in 2.4GHz antenna compact 15x29mm (including antenna).
DIY mobile power, car power, communications equipment and power supply.
Technical Parameters:

The RF receiver modules are widely used for data receiving and signal control. They are specified as preferred components in remote control garage, roller curtain, door locks, remote sensing, telemetry, industrial control and wireless security alarm industry.
Fixed turn the lamp current to 0.1 times the value of the constant current (charge when used to identify whether the battery is full);
2. Increased input reverse polarity protection diode;
3. Using dedicated reference IC, and high-precision sampling resistor, so that the constant current is more stable, (20 degrees to 100 degrees, the constant current 1A, when the temperature drift of less than 1%).Particularly suitable for LED driver
*High-power LED constant current drive
*Lithium battery charger (including ferroelectric)
Max voltage: 16V
Minimum voltage: 5V
Continuous current: 10A
Short maximum current: 20A (less than 10 seconds)
Speed control mode: PWM step-less speed regulation, can also be used to adjust the light
Control mode: speed control potentiometer (clockwise clicked open, continue to rotate clockwise from 1% to 99% speed)
Duty cycle: 0%-99% (0% position is the state of the switch off when the potentiometer is most on the left).
When the current is switched on, the 0.002A (long time no need to switch off the governor is no current).
Efficiency: the maximum efficiency is as high as 98%.
Volume: long 3cm (excluding potentiometer), width 2cm, height 1.4cm
