Quectel BG770A-SN industrial IoT module offers 5G, NB-IoT, and NTN satellite connectivity

Quectel has recently released the BG770A-SN industrial IoT module which comes in an ultra-compact form factor and supports both NTN and TN and features GNSS for positioning functionality. This 5G-ready module also supports iSIM and utilizes the GEO satellite constellation for worldwide coverage. Additionally, the module offers integrated security elements (ISE) and can operate in between the industrial temperature range of -40°C to +85°C.

Previously we have written about the Quectel BG95-S5 5G NTN + LTE IoT module which supports NTN satellite (L-band and S-band) plus LTE Cat M1, Cat NB2, and eGPRS as fallback options, designed for applications where continuous connectivity is critical. We have also written about the Quectel CC660D-LS IoT-NTN module, which is an IoT NTN module designed specifically for Skylo’s satellite network. The new BG770A-SN module is a little different from the previous two because it supports LTE Cat M1, LTE Cat NB1/NB2, and NTN over NB-IoT. in simple terms, this new module is designed for low-power wide-area (LPWA) with satellite as a backup option.

The company mentions that it features ultra-low power consumption thanks to a MIPS 5150 processor and integrated RAM and flash, which help reduce current consumption to low levels in various modes, including PSM, e-I-DRX, etc. It is further integrated with a GNSS engine that supports GPS and GLONASS systems. These features along with standard interfaces and functionalities make this module suitable for applications, such as wireless POS, smart metering, tracking, wearable devices, and many more.

The BG770A-SN industrial IoT module can be purchased from DigiKey and Mouser. On DigiKey, the price is $48.50 for a single unit, while on Mouser, you must order a full reel in multiples of 500 units, costing around $14,375 for 500 units. More information about the product is available on the product page and press release.
