UART Mapping (Ardupilot)

• SERIAL0 -> USB
• SERIAL1 -> UART1 (MAVLink2, DMA-enabled)
• SERIAL2 -> UART2 (DisplayPort, DMA-enabled)
• SERIAL3 -> UART3 (GPS, DMA-enabled)
• SERIAL4 -> UART4 (MAVLink2, DMA-enabled)
• SERIAL5 -> UART5 (DMA-enabled)
• SERIAL6 -> UART6 (RCIN, DMA–enabled)
• SERIAL8 -> UART8 (DMA–enabled)

UART Mapping (PX4)

• ttyACM0->USB
• ttyS0->TELEM1 -> UART1
• ttyS1->GPS2 -> UART2 
• ttyS2->GPS1 -> UART3 
• ttyS3->TELEM2 -> UART4
• ttyS4->TELEM3-> UART5
• ttyS5->RC -> UART6
• ttyS7->TELEM4/SERIAL4 -> UART8

RC Input (Ardupilot)

The default RC input is configured on the UART6. The SBUS pin is inverted and connected to RX6. Non SBUS, single wire serial inputs can be directly tied to RX6 if SBUS pin is left unconnected. RC could be applied instead at a different UART port such as UART2, UART4 or UART8, and set the protocol to receive RC data: SERIALn_PROTOCOL=23 and change SERIAL6 _Protocol to something other than 23.

 

OSD Support  (Ardupilot)

The MicoAir743v2-AIO supports OSD using OSD_TYPE 5 (MSP_DISPLAYPORT).

 

VTX Support

The SH1.0-6P connector supports a DJI Air Unit / HD VTX connection. Protocol defaults to DisplayPort. Pin 1 of the connector is 12v so be careful not to connect this to a peripheral requiring 5v.

 

PWM Output

The MicoAir743v2-AIO supports up to 9 PWM outputs.

Channels 1-8 support DShot/bi-directional DShot.

(currently PX4&INAV not support BDShot function)

PWM output share grouped and every group must use the same output protocol:

1,2,3,4 are group 1

5, 6 are group 2

7,8, 11are group 3

Note: PWM11 is the “LED” pin. If this is configured for serial LED use then PWM 7 and 8 can only be used as serial LED also.

 

Compass

The MicoAir743v2-AIO doesn’t have a built-in compass sensor, but you can attach an external compass using I2C on the SDA and SCL connector.

We suggest our customers upgrade their modules and receivers' ELRS version to 3.3.0. Significantly,
the module and receiver have to be in the same ELRS version, otherwise, the frequency cannot match successfully.

Click to download the firmware of the ELRS Nano Receiver(V3.3.0 Version).


Know More About ExpressLRS
ExpressLRS is an open-source RC link for RC applications. Everyone could find this project on Github or join the discussion in Facebook Group.

ExpressLRS is based on Semtech Lora SX127x or SX1280 hardware for RX and TX respectively. it aims to achieve the best possible link performance
in both speeds, latency, and range. At 900 MHz a maximum of 200 Hz packet rate is supported. At 2.4 GHz a blistering 500Hz is currently supported
with a custom OpenTX build. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.

More and more vendors start to support the ExpressLRS radio protocol in different parts, like radio transmitter with ELRS in stock, drone with built-in
ELRS receiver, ELRS TX module for JR bay, or Nano bay. BETAFPV team take part in this project and provide a series of ExpressLRS components.



Configuration & Bind
ExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the receiver and the flight controller board.
So make sure your flight controller board supports the CRSF serial protocol.
Next, we use the flight controller with Betaflight firmware to show how to set up the CRSF protocol.

The connection between the ELRS Nano receiver and the FC board is shown below.
Enable the corresponding UART (e.g. UART3 below) as a Serial Rx on Betaflight Configurator "Ports" tab.


On the "Configuration" tab, select "Serial-based receiver" on the "Receiver" panel, and select "CRSF" as the protocol.
Telemetry is optional here and will reduce your stick update rate due to those transmit slots being used for telemetry.

Nano receiver could enter binding status by power on/off three times.

• Plugin and unplug nano receiver three times;
• Make sure the LED is doing a quick double blink, which indicates the receiver is in bind mode;
• Make sure the RF TX module or radio transmitter enter binding status, which sends out a binding pulse;
• If the receiver has a solid light, it's bound.

Note: Binding once and the receiver will store the binding information. Re-power and the connect successfully auto.
