1 Overview
LTE-LINK SE is a multifunctional link system suitable for open source flight control
equipment and camera video data acquisition and transmission. The system works in a 4G
network environment and is used with the CUAV cloud platform APP to realize open source
flight control equipment and camera video Unlimited distance transmission of data. The system
uses 12V ~ 55V DC power supply as power, and a wide range of working voltage is compatible
with the power supply system of most drones on the market.
In terms of system upgrade and update, the product can upgrade the system version of the
device to the latest version officially released by CUAV Cloud, allowing users to use the system
upgrade to bring more convenient and complete functions, while also being able to experience
the latest open source flight control protocol technology. In terms of product maintenance and
processing, the system provides the function of restoring the system. If the current system is
abnormal, the user can use this function to restore the system.
The system adopts OLED display, complete status information indication, simple operation,
running status stable and reliable, it is a link device that successfully solves the open source
flight control infinite distance control and the infinite distance collection and transmission of
camera video data.
1.1 Product Feature
Efficient 32-bit ARM processor
SIM card compatible with multiple operators
Unlimited distance data transmission, the data is processed by the ChaCha20-Poly1305
encryption algorithm
Support multi-platform cloud management
Provide remote online upgrade and offline upgrade of equipment

1.2 Main purpose and scope of application
Drone flight control
Automatic cruise equipment (such as automatic cruise car, automatic cruise yacht)
Unlimited distance camera monitoring equipment
1.3 Safety
The device power cord and flight control data transmission line should use the interface
line matched by the product to avoid chip damage.
When the device is working in an environment with poor heat dissipation for a long
time, do not touch the device directly with your hands. You should disconnect the
power supply and wait for the surface temperature of the device to drop before
removing it.

3.2.2 Hardware and interface description
OLED display screen：Display LTE-LINK SE system status information.
SIM card slot：Used to access the SIM card.
Power status light：Indicates the current power supply situation of the device. If the
indicator is found to be off after power-on, it indicates that the power supply of the
device is abnormal.
System status light：When system normal operation indicator and the system is in
normal operation state, the indicator flashes at a frequency of 1s.
NIC status light：Indicates the current network status of the 4G network card. When it
flashes twice continuously within 1s, it means that the current network card is not
inserted into the SIM card or the inserted SIM card cannot connect to the network
service; when it flashes once within 1s, it means the current network card has been
inserted to the SIM card which is capable of connecting to the network ; when it is
always on, it indicates that the network card has successfully dialed in and the device
can use network services through the 4G network.
Power connector：Power supply for equipment.
Button：Used for account device binding, device CID QR code display and device
system restoration.
