Pocket P.C. devkits ship, U-blox GNSS module replaced by SIMCom SIM33ELA

The Pocket P.C. (aka Popcorn Computer) is a handheld Linux computer based on Allwinner A64 with 2GB RAM, 32GB storage, a 4.95-inch Full HD display, and a QWERTY keyboard that was introduced in 2019, and reminds me of PocketCHIP from a few years also with an Allwinner processor, a display, a keyboard, and a battery. The initial plan was to start shipping the device by May 2020, and there are been delays for reasons we’ll explain below, but the good news is that Source Parts has just announced the developer units had been shipped. So what happened exactly, besides the COVID-19 pandemic, government lockdowns, and supply chain disruptions? Source Parts first encountered issues with the quality of PCBs delivered by the manufacturer, which ended up with them having to switch to a new manufacturer. Getting the display to work was also a challenge, and Icenowy, a developer involved with linux-sunxi […]

u-blox EVK-LEXI-R10 evaluation kits feature LEXI-R10 LTE Cat 1bis and MAX-M10S GNSS modules for Cellular IoT and GPS connectivity

u-blox has developed the EVK-LEXI-R10 evaluation kits to help engineers test and evaluate their LEXI-R10 LTE Cat 1bis cellular modules. These compact modules support data speeds of up to 10Mbit/s for downloads and 5Mbit/s for uploads, all while using very little power. They also include built-in Wi-Fi to scan indoor hotspots and work with u-blox’s CellLocate service for both indoor and outdoor tracking. Available in regional variants, the boards and kits are certified by major mobile operators, including those in the US. The LEXI-R10 series by u-blox features the world’s smallest LTE Cat 1bis modules in the LEXI LGA form factor. The EVK-R10 kits simplify the evaluation of these multi-band LTE Cat 1bis modules. The EVK-R10401D kit supports the LEXI-R10401D module for North American operations, the EVK-R10801D kit supports the LEXI-R10801D module for Europe, Middle East, Africa, and Asia-Pacific, and the EVK-LEXI-R10001D kit supports the LEXI-R10001D module with global coverage.

SparkFun’s latest GNSS breakout board features u-Blox NEO-F10N L1/L5 dual-band receiver for urban environments

The SparkFun GNSS L1/L5 Breakout is a standard precision GNSS board with meter-level positional accuracy that features the u-Blox NEO-F10N dual-band module, an SMA antenna connector, and a USB-C port for power and data. As its name implies, the board relies on the L1/L5 bands of the NEO-F10N instead of the more commonly seen L1/L2 bands and delivers better performance in urban environments. That’s because the L5 band falls within the protected ARNS (aeronautical radionavigation service) frequency band leading to less RF interference. SparkFun GNSS L1/L5 Breakout specifications: GNSS u-Blox NEO-F10N module with L1/L5 dual-band GNSS receiver Concurrent Reception of GPS, Galileo, and Beidou Integrated SMA Connector Time to First Fix: 28s (cold), 2s (hot) Max Navigation Rate for Single GNSS Configuration (GPS): 20 Hz Positional Accuracy (GPS) – 1.5m Time Pulse Accuracy – 30ns Operational Limits Max G: ≤ 4G Max Altitude: 80km Max Velocity: 500m/s Supports NMEA, UBX […]

u-blox XPLR-IOT-1 explorer kit embeds cellular IoT, Wi-Fi, BLE, GNSS, and sensors for IoT evaluation

u-blox XPLR-IOT-1 explorer kit is an all-in-one IoT evaluation platform with cellular IoT, Wi-Fi, Bluetooth Low Energy, and GNSS, plus some sensors to evaluate various IoT products and enable proofs of concepts such as logistics container trackers, industrial automation, sensor-to-cloud applications, and fleet management solutions. The device’s main module is the u-blox NORA-B106 with a dual-core Arm Cortex M33 microcontroller and Bluetooth LE 5.2 radio that host the application software and control the other modules, namely the SARA-R510S module for LTE-M and NB-IoT cellular connectivity, NINA-W156 2.4 GHz Wi-Fi module, and the MAX-M10S GNNS module. The XPLR-IOT-1 platform is also equipped with an accelerometer, a gyroscope, a magnetometer, and temperature, humidity, pressure, and ambient light sensors. u-blox XPLR-IOT-1 specifications: Main MCU – Nordic Semi nRF5340 dual-core Arm Cortex M33 @ 128/64 MHz with 512 + 64 kB RAM memory and 1024 + 256 kB flash (found in NORA-B106 module) Wireless […]

Quectel LG290P is the world’s first quad-band GNSS module (L1, L2, L5, and E6)

The Quectel LG290P is a quad-band, multi-constellation, high-precision, real-time kinematic (RTK) GNSS module that supports GPS, GLONASS, Galileo, BDS, QZSS, and NavIC constellations. A typical GNSS module like the SparkFun GNSS L1/L5 can receive signals from only one or two frequency bands, but the Quectel module can receive signals from four different frequency bands (L1, L2, L5, and E6) simultaneously and features built-in anti-jamming technology for improved signal reception in challenging environments. All these measures make this chip suitable for high-precision navigation applications like autonomous robots, UAVs, precision agriculture, surveying and mapping, and autonomous driving. Previously we have written about higher precision GPS modules like the SparkFun RTK EVK module, SparkFun RTK Torch module, the Cavli C17QS IoT GNSS module and much more feel free to check those out if you are interested in those topics.

SparkFun RTK EVK offers GNSS with centimeter accuracy, WiFi, Bluetooth, 4G LTE Cat 1, and Ethernet connectivity

SparkFun RTK EVK is a fully-enclosed GNSS platform designed for fixed or mobile high-precision positioning and navigation applications with centimeter accuracy thanks to RTK (real-time kinematic) technology implemented with modules from u-blox. About two months ago, Sparkfun introduced the RTK Torch waterproof GNSS surveyor with Unicore UM980 GNSS module with RTK support, ESP32 for WiFi/Bluetooth, and an STM32WLE5C LoRa SoC. The  SparkFun RTK EVK (evaluation kit) may drop LoRa connectivity, but it’s a more versatile platform with WiFi, Bluetooth, Ethernet, and LTE Cat 1 cellular connectivity, besides support for L1 + L2 RTK GNSS with L-Band correction. Sparkfun RTK EVK specifications: GNSS Receiver – u-blox ZED-F9P Concurrent reception of GPS, GLONASS, Galileo, and BeiDou Receives both L1C/A and L2C bands 184-channel u-blox F9 engine Time to First Fix: 25s (cold), 2s (hot) Max Navigation Rate: 20Hz / 25Hz depending on mode Horizontal Position Accuracy: 2.5m without RTK; 0.010m with RTK […]
