Binding Procedure

The Micro receiver comes with officially major release V2.0.0 protocol and has not been set for a Binding Phrase. So please make sure the RF TX module works on officially major release V2.0.0 protocol and no Binding Phrase has been set beforehand.

• Enter binding mode by plugging in and unplugging the Micro receiver three times;
• Make sure the LED is on double flashing, this indicates the Micro receiver is in bind mode;
• Make sure the RF TX module or radio transmitter also enters the binding mode, which sends out a binding pulse;
• When the LED light is solid, it indicates that the devices are successfully bound.

Note: once the devices have been successfully bound, the receiver will store the binding information. There would be no need for re-bind on the later use as the devices would be connected automatically.

Note: If you reflash the firmware of the Micro receiver with your own Binding Phrase, please make sure the RF TX module has the same Binding Phrase to perform an auto bind.

Failsafe and PWM Output

When the connection or signal is lost between the radio transmitter and receiver, the failsafe function will adjust all the channels to the failsafe values set by the users, maximum keep safety and prevent from flying away. It’s necessary to set up failsafe values properly if you are not using a flight controller, such as RC fixed-wing.

• Power on the Micro receiver and wait for 20 seconds without binding.
• Once the indicator is flashing quickly, the receiver’s WiFi has been activated.
• Connect WiFi via computer or mobile phone.
• WiFi Name: ExpressLRS RX
• WiFi PWD: expresslrs
• Open the website address: http://10.0.0.1, and set your own failsafe values.

Note: Failsafe values are absolute and do not use the “invert” flag.
