Description

BETAFPV Micro receiver is based on the ExpressLRS project, an open-source RC link for RC applications. ExpressLRS aims to achieve the best possible link performance in both speeds, latency, and range. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.

Diagram of LiteRadio 2 SE

Below is the diagram for ELRS Micro receiver.

Note: The firmware version of the micro receiver manufactured by our company is ELRS 2.0.0. ELRS Innovative team has officially released version 2.0.0, which is not compatible with the 1.x version. Significantly, the TX module and receiver have to be in the same ELRS version, otherwise, the frequency cannot match successfully.

Note: The Micro receiver also supports flash CRSF output firmware, in this case CH2 corresponds to TX and CH3 corresponds to RX.

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.

Package:

• 1 * ELRS Micro Receiver
• 1 * BETAFPV 80mm T antenna

Note: ELRS Micro Receiver is upgraded to the V1.2 version with two problems fixed. CH1 or CH2 was unable to output the PWM signal when connecting some brands' servos or could not drive some servos like MG90S/SG90/FMS/MG995. Now the two problems have been resolved. Please rest assured to purchase. If you have any questions, please feel free to contact us.
