Hezhou luat Kunlun mirror development board Air724

Kunlun Mirror Multi-Function Positioning Development Board - is a newly launched 4G+GNSS positioning two-in-one series of demonstration boards by Hezhou. The main control adopts Hezhou's classic 4G Cat.1 module Air724UG, and the GPS is compatible with 1612 universal package and Hezhou Air530 series small Package positioning module.

The Kunlun Mirror supports lithium battery power supply, and with its built-in IPS LCD, it can directly display positioning information/maps. It is very convenient to take it outdoors to test the GPS positioning function.

Based on the efficient development of LuatOS, the schematics/PCB/source code of the Kunlun Mirror development board are all open source, allowing users to conduct secondary development flexibly and conveniently, comprehensively improving development efficiency.

In addition to positioning (star map/signal-to-noise ratio/GPS positioning information) and map display, the Kunlun Mirror development board also has cool functions such as shake divination, ball balancing, electronic compass, and lantern control. Function switching can be performed through the up and down keys on the development board, and the left and right keys control cancellation/confirmation.

Main functions of Kunlun mirror development board

01. Star map data

The Kunlun mirror development board can display GPS star map data based on the visible satellite information field read through the serial port. The only analyzed satellite information is GPS and Beidou data. The dark green satellite number is GPS and the light green satellite number is Beidou.

02. Signal-to-noise ratio

The satellite signal-to-noise ratio of GPS and Beidou is displayed as a histogram, the signal value is displayed as a yellow value, and the satellite number is a green value.

03. GPS positioning information

It can display positioning information such as positioning status, altitude, speed, longitude, and latitude.

04. Map positioning display

Supports display of flat maps and satellite maps. This function needs to be connected to the Internet. After entering the map function, the picture will be refreshed every minute by default. The refresh frequency can be adjusted according to actual needs. Please pay attention to the traffic usage.

05. Shake divination game

The fortune-telling function is mainly to display the collection of sensor acceleration. Just shake the development board after entering the interface. Divination information is taken from the Book of Changes and is for entertainment purposes only.

06. Electronic compass

This function mainly displays the geomagnetic data collection of the sensor. Before using it for the first time, it needs to be calibrated by collecting data. Just keep it horizontal (around the Z axis) and rotate it for two to three turns. The current direction can be judged by the collected magnetic flux.

07. Sensor balancing ball

This function mainly displays the angular velocity collection and calculation of the sensor, and is also very good as a casual game in daily life.

08. Lantern control

The development board is equipped with RGB LED lights, which can display a variety of colors. It is equipped with 17 modes by default, and the display mode can be switched by pressing the up and down keys.

09. Game porting

Supports secondary development and can transplant various classic mini-games.
