Product Name

Raspberry Pi Zero-4G-HUB Expansion Board Air780e Networking Module AIR780E-4G Module SL2.2S-USB Conversion Chip Drive Free Communication Plug and Play

About

The Air780E networking module on the Air780e expansion board of the LC Raspberry Pi Zero_4G.HUB is an LTE Cat.1 bis communication module launched by Luat Communication.
It has 4G full network and can be used by inserting a card, which can adapt to different operators and products. By default, it uses AT firmware and onboard SL2.2S-USB conversion chip.
The Raspberry Pi Zero is connected to the USB signal line of the module through a top pin, realizing USB one to three Type_C port expansion. It is plug and play,
with commonly used pins for easy secondary development.

Instructions for use

1. Insert any carrier's SIM card into the expansion module, then stack the module with the Raspberry Pi Zero development board,
install the copper pillar and tighten the screws to ensure that the top pin of the module is on the four USB test points on the back of the Raspberry Pi, as shown in the figure:


2. Power on the Raspberry Pi Zero development board (It is recommended to use the power supply port that comes with the Raspberry Pi.
If you use the power supply port of the expansion module, the power supply pin may shift slightly when the development board is bumped,
causing the board to power down and restart).After the power is turned on, plug in an external USB device, such as a mouse, keyboard, USB drive,
etc., and the Raspberry Pi will automatically recognize the device, as shown in the following figure:




3. Network function testing
After inserting an available SIM card, the system will automatically recognize the 4G module as eth0.
Open the system terminal and enter "ifconfig - a" to query the current network configuration.
The eth0 column in the figure represents the network configuration of the SIM card:
