SparkFun has released the Quadband GNSS RTK Breakout featuring the Quectel LG290P module designed for high-precision real-time kinematic (RTK) applications. It supports GPS, GLONASS, Galileo, BDS, QZSS, and NavIC constellations, with the ability to simultaneously receive signals from L1, L2, L5, and L6/E6 frequency bands. The module includes support for SBAS augmentation systems (e.g., WAAS, EGNOS, GAGAN) and PPP services (e.g., BDS PPP-B2b, QZSS CLAS), delivering reliable positioning with fast convergence times for precision navigation tasks. The breakout board offers a compact design (43.2 x 43.2mm) and multiple expansion options including 24 PTH pins, dual 4-pin JST Qwiic connectors, three UART interfaces, a USB-C connector, and additional PTH pins for BlueSMiRF/Serial-to-UART. With its RTK support and advanced GNSS capabilities, the board is ideal for applications requiring high-accuracy positioning and robust navigation performance. Previously, we covered several GNSS boards including the SparkFun GNSS L1/L5, u-blox EVK-LEXI-R10, and Conexio Stratus Pro and [...]

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 [...]
