Feather compatible shield Integrates BG96 Module with LTE Cat-M1, NB-IoT, and GPS
Last week, I wrote about the Pebble Board, an nRF9160 based LTE-M and NB-IoT GPS tracker board that connects with Thingsboard. I was soon informed about a similar solution based on Quectel BG96 and compatible with the Feather form factor. Meet IoT-Bots.com’s qTop Adafruit Feather Compatible shield. In case you wonder, why they did not call it a FeatherWing, that’s because as it’s slightly larger, and the boards are “Adafruit Feather Compatible (AFC) from the interface connection perspective only.” Key features and specifications: Wireless module – Quectel BG96 Cellular – LTE Cat M1, NB-IoT, and EGPRS module offering maximum data rates of 375 kbps downlink and uplink GNSS – GPS, GLONASS, BeiDou/Compass, Galileo, QZSS Nano SIM card holder and u.FL connector (3) for cellular connectivity u.FL connector (4) for GNSS Expansion Feather expansion connector (11) 6-pin qJam interface connector (12) with I2C for extra sensors Misc – Network status LED, […]

Android’s 3D mapping aided GPS enables improved urban GPS accuracy
One of the best features of smartphones is GNSS location with standards like GPS that allows you to get directions or share your location with friends or business contacts. It works great in most cases, but getting an accurate location may be challenging in urban areas due to tall buildings that block the signal to the satellites and create reflections. This can be an issue for ride-sharing apps for example, as the applications may detect the wrong side of the street you are on, either forcing the client to cross the street (when possible) or the driver to take a detour to reach your location. This problem may soon go away in Android phone thanks to 3D mapping aided GPS corrections. So how does that work exactly? Google explains: The 3D mapping aided corrections module includes tiles of 3D building models that Google has for more than 3850 cities around […]
