Great value, needs careful wiring
The module itself is powerful and supports all the bands I need. Just be careful with the voltage supply; it needs a stable 3.7V source to avoid boot loops. Once powered correctly, it's very reliable.

Excellent 4G Cat.1 Performance
Upgraded from an old SIM800L to this 4G module. The latency is significantly lower, and the MQTT throughput is much better for sending sensor data. Highly recommended for modern projects.

Easy integration with STM32
Used this with an STM32F103 board. The UART communication is clean, and the AT commands are standard. Documentation could be slightly more detailed, but online resources fill the gaps easily.

Best bang for your buck
For the price, you cannot beat the features. Full netcom support means it works with any carrier SIM card I tested. The sleep mode current is also quite low, perfect for battery-powered apps.

Solid module for remote monitoring
Deployed five of these for remote weather stations. They have been running for two months without disconnection. The only minor issue is the IPEX connector feels a bit delicate during assembly.

Perfect for IoT Prototyping
This Air780E module works flawlessly with my Arduino Uno. The MQTT connection to OneNet was established within minutes using the provided AT command set. Signal stability is impressive even in fringe areas.
Q: Is the MQTT protocol built-in or do I need to code it?
A: The MQTT client functionality is built into the firmware. You can configure and connect to an MQTT broker like OneNet directly using specific AT commands without coding the stack yourself.
Q: Does this module require an external antenna?
A: Yes, the Air780E module has an IPEX connector and requires an external 4G/LTE antenna with an IPEX plug for optimal signal performance.
Q: What size SIM card does this accept?
A: The onboard slot is designed for a Standard SIM (Mini-SIM). If you have a Micro or Nano SIM, you will need a physical adapter to fit it into the slot.
Q: Does it support SMS functionality?
A: Yes, the module fully supports sending and receiving SMS text messages via standard AT commands, in addition to data services.
Q: Can I use a 5V Arduino directly to power this?
A: No, the module operates between 3.3V and 4.2V. You must use a voltage regulator or a dedicated power bank to step down 5V to approximately 3.7V to prevent damage.
