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 the world. Google Play services 3D mapping aided corrections currently […]
We’ve been writing about Techbase Modberry industrial embedded computers with DIN-Rail enclosures such as Modberry M500 or M2000 for several years. Most of their systems are powered by SBC’s like Raspberry Pi 4 or AAEON Up Squared, but they’ve also made models based on Raspberry Pi Compute Module 3+, and with the launch of Raspberry Pi CM4, the company has now introduced Modberry 500 CM4 industrial computer powered by Raspberry Pi Compute Module 4 with up to 8GB RAM and 32GB eMMC flash. Modberry 500 CM4 key features and specifications: SoM – Raspberry Pi Compute Module 4 with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 1 to 8GB RAM, up to 32GB eMMC flash.

The Raspberry Pi board has long been able to connect to cellular networks either via USB dongles or 3G or 4G LTE HATs that often include GPS as a bonus. But you can now connect your Raspberry Pi 4 or other RPI SBC with a 40-pin header to 5G networks thanks to Waveshare SIM8200EA-M2 5G HAT for Raspberry Pi powered by Qualcomm Snapdragon X55 multi-mode multi-band modem offering 5G/4G/3G cellular connectivity. As we can see from the photo, the 5G add-on comes as part of a cool-looking kit with bottom and top acrylic plates, spacers, a cooling fan plus five antennas for cellular and GNSS connectivity. But the HAT itself integrates a SimCOM SIM8200EA-M2 M.2 module and offers the following specifications: Compatibility – Works with Raspberry Pi boards with a 40-pin GPIO extension header Cellular Connectivity SIM8200EA-M2 core module based on Qualcomm Snapdragon X55 platform with multi-mode multi-band support 5G/4G/3G networks support SIM card slot compatible with 1.8V / 3V […]
We’ve previously covered small waterproof LTE Cat M1 and NB-IoT GPS trackers such as Mictrack MT825, but AirBolt GPS tracker offers another option and promises an even longer battery life of up to 12 months. At 37 x 34 x 11mm, AirBolt GPS may also be the world’s smallest waterproof GPS tracker on the market, as well as the lightest at just 21 grams, both of which are characteristics that make the tracker especially suitable for pets like cats and dogs, as well as track luggage, keys, bicycles, etc… AirBolt GPS tracker key features and specifications: SoC(s) Unnamed, but considering Nordic Semi is listed as a partner it should be nRF9160 SiP with Arm Cortex-M33 MCU core, 1024 KB flash, 256 KB SRAM, NB-IoT, LTE Cat M1, and GPS connectivity There’s also Bluetooth 5.1 so one of the nRF52 chips might also be included. Connectivity Bluetooth 5.1 with long-range and direction-finding support Cellular – Worldwide support via NB-IoT and LTE […]
CNXSoft here. I’ve been tasked with reviewing Famisafe parental control app for Android and iOS acting both as a parental control app and phone tracker app and designed for parents who want to track their kids’ location and better control when to use the phone and what content they may access. The first thing to get started is to download the free trial on either Android or iOS. I actually downloaded both versions for FamiSafe for this review, since I used Huawei Y9 Prime 2019 (Android 10) as the “parent” smartphone, and an iPhone 6 as the “kid” phone. Famisafe Initial Configuration We’ll have to start with the “parent” phone. After a welcome screen explaining some of the main features including offensive content detection, device & app usage rules, web filter, etc.. you’ll be asked to select whether it’s the parent or kid device. Once we select “Parent” we’ll be shown the differences between the Free and Premium version. The […]
We’ve often written about iWave Systems’ single board computers, development kits, and systems-on-module, but the company has also been offering automotive products such as a Linux based OBD-II Dongle. And they’ve just introduced a new one called Telematics Control Unit (TCU) based on an Arm Cortex-A7 processor and offering GPS, 4G LTE Cat 4/1/M1, WiFi 5, and Bluetooth 5.0 connectivity for vehicle fleet management and insurance companies that want to know how drivers behave… iWave Telematics Control Unit (TCU iW-G26) specifications: Processor – Arm Cortex-A7 based CPU @ 792MHz (likely NXP i.MX 7ULP) System Memory – 256MB DDR3L SDRAM Storage – 4GB eMMC Flash Connectivity 4G LTE Cat 4, Cat 1, Cat M1 (eMTC) 802.11b/g/n Wi-Fi 4 or 802.11b/g/n/ac Wi-Fi 5 (Hotspot & Station mode) Bluetooth 5.0 GNSS – GPS/A-GPS receiver with antenna Sensors – 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer OBD Features & Protocols 12V Power Input from TCU Port USB 2.0 device CAN 1x HS CAN bus J1962 […]
RAK Wireless launched its first Mini PCIe LoRaWAN concentrator module in 2018 with RAK833 mPCIe card featuring Semtech SX1301 LoRa baseband chip. It was soon followed by RAK2247 mPCIe with a very similar design but some tweaks to increase its maximum transmission power and range, and improve thermals and stability with the addition of a heatsink. The company has now introduced a new version with RAK2287 Mini PCie LoRaWAN concentrator module being mostly inspired by RAK2247 module but replacing Semtech SX1301 by Semtech SX1302 LoRa transceiver that’s suppose to reduce current consumption (and heat), lower the BoM cost, and able to handle a higher amount of traffic. The new mini PCIe card also adds u-blox ZOE-M8Q GPS system-in-package to provide GNSS functionality. RAK2287 key features and specifications: LoRa Connectivity Semtech SX1302 LoRa Transceiver with 2x SX1250 Tx/Rx front-end Tx power – up to 27dBm Rx sensitivity – down to -139dBm @ SF12, BW 125 kHz LoRaWAN® 1.0.2 compatible.
