Adding GPS to Pavo20/Pavo20 Pro

This document only provides information on how to correctly connect and initialize configure the GPS. Parameters such as GPS Rescue are subject to personal adjustment.

Connecting GPS module

RX point on GPS connects to TX joints on FC, TX point connects to RX joints.

GPS connects to UART1 port for example, connecting diagram as below:

Initial GPS Configuration

On Ports page, set sensor imput on UART1 as GPS, set baudrate as AUTO, then save and reboot.

(Baudrate would be different according to GPS module. If it is uncertain, comfirm it to manufacturers that built this GPS module.)

On Configuration page, enable GPS option, then save and reboot.

On GPS page, set GPS protocol correctly, and open "Auto config",save and reboot.

After finishing all the settings ,reconnect battery to FC, wait for GPS icon to light up, which means GPS configurations are completed.

(If the GPS icon is red, it needs to go outside the room to pick up signals. If there is no GPS icon lighting up, make sure the connection and configuration are all correct.)

Magnetometers on GPS or Compass

If you are connectiong a GPS or a compass on FC with magnetometers (6pins), solder the extra SCL or SDA points on FC:

Auto-detect FC, add magnetometers in other options,then flash it an online firmware:

After flashing,entering CLI commands as below:

(B08 & B09 wouldn't interfere with other resources.)

resource I2C_SCL 1 B08

resource I2C_SDA 1 B09

set mag_i2c_device = 1

save

Basically the magnetometers should be recognized.

Because F4 2-3S 20A AIO FC doesn't have a pull-up resistor, some magnetic compasses may not be recognized. You can try enabling the internal pull-up by entering the following CLI command:

set i2c1_pullup = ON

save

Adding a buzzer to Pavo20/Pavo20 Pro

The Pavo20 drone uses the F4 2-3S 20A AIO V1.0 flight controller, which comes with the motor buzzer function enabled by default. If you need to connect an external buzzer, simply solder it to the BUZZ- and BUZZ+ ports on the flight controller. The default control channel is AUX3.

Settings details

On the mode page, keep the default AUX3 settings or customize the mapped channels to your preference (switch to automatic, then adjust any knob and save).

Configuration page: Enable or disable the corresponding functions as needed, then save and restart.
