2. EXAMPLE CONNECTIONS:
 
 | 
 
 | 
 
 | 
 
 | 
'P' outputs are either 3.3v or 0v (ground). Leds need resistors to limit current to no more than 20mA. High brightness leds allow a lower current which is preferred (eg: 2-5mA). Google will reveal how to select resistor values but 220-470ohms will be safe starting values.
The 'L' pad monitors the voltage of a battery when used with a voltage booster. This allows the receiver/motor to be powered with a boosted voltage and benefit from the convenience of a smaller battery, typically a single lipo. The receiver will cut power to the motor when the battery voltage falls to the LVC voltage.
3. BINDING
Bind once:
1. Switch Rx on and wait ~20s until led flickers fast.
2. Switch Tx on in bind mode.
3. Rx led should flash slowly; wait for it to go solid.
Change distance between Tx/Rx if binding does not work.
4. LED:
Led On  = perfect reception (real-time indicator).
1 flash = Scanning (~2sec between flashes; no signal or not bound if never stops).
2 flash = Model currently not selected (Selecta).
5 flash = LVC/Brownout (voltage went too low; check battery/motor load).
5. PAPERCLIP CHANGES:
The following changes can be made by simply shorting two pads together (eg: with a paperclip):
1. Perform a 'Hard reset' (factory reset).
2. Change motor control between 'low off' and 'center off'.
3. Enable/disable LVC (eg: when using Nicads, NiHMs, LiFe cells).
4. Enable/disable Selecta.
5. Enable/disable Cruise Control/Failsafe.
'Paperclip' changes
6. PROGRAMMING:
This receiver has many other options that are described on the features page.
These are changed using a technique called 'programming': v611.
