u-blox ZED-X20P all-band GNSS module delivers global centimeter-level accuracy at a 90% lower cost (TCO)
Previously u-blox announced the release of the X20 series of all-band GNSS modules, but at the time, the company did not disclose detailed specifications for the module. Recently, they have launched the ZED-X20P all-band GNSS module designed to deliver centimeter-level global positioning at a significantly lower cost, up to 90% less than traditional solutions when considering the total cost of ownership. The module supports L1, L2, L5, and L6 bands across four GNSS constellations (GPS, Galileo, GLONASS, and BeiDou), along with SBAS, QZSS, and NavIC. Additionally, the module is compatible with PPP-RTK, network RTK, and global PPP correction services, along with u-blox’s PointPerfect and Galileo’s free High Accuracy Service (HAS), ensuring precise and flexible positioning. It also features secure boot, signed firmware, encrypted communication, and anti-jamming capabilities, for critical applications. The ZED-X20P maintains the ZED form factor, making the footprint compatible with the ZED-F9P chip for easier upgrades. u-blox says […]
STMicro releases Teseo VI quad-band GNSS receivers for automotive and robotics applications
STMicro has launched the Teseo VI family of global navigation satellite system (GNSS) receivers for high-volume precise positioning applications. These quad-band GNSS receivers support multiple constellations and frequency bands, enabling high-accuracy positioning for various automotive and robotics applications. The Teseo VI quad-band GNSS receivers are described as the first chips in the market to “integrate multi-constellation and quad-band signal processing in a single die.” The single-chip design allows for compact products and accelerates time to market. The new Teseo VI GNSS family includes the Teseo VI STA8600A, Teseo VI+ STA8610A, and the Teseo APP2 STA9200MA. All variants integrate dual independent Arm Cortex-M7 cores with ST’s proprietary phase change memory (PCM) technology, eliminating the need for external memory. They are targeted at applications in advanced driving systems, autonomous vehicles, asset tracking, smart agriculture, and robot deliveries. Other quad-band GNSS modules include the Quectel LG290P and u-blox X20. Teseo VI STA8600A, VI+ […]
Solar-powered LLM over Meshtastic solution may provide live-saving instructions during disasters and emergencies
People are trying to run LLMs on all sorts of low-end hardware with often limited usefulness, and when I saw a solar LLM over Meshtastic demo on X, I first laughed. I did not see the reason for it and LoRa hardware is usually really low-end with Meshtastic open-source firmware typically used for off-grid messaging and GPS location sharing. But after thinking more about it, it could prove useful to receive information through mobile devices during disasters where power and internet connectivity can not be taken for granted. Let’s check Colonel Panic’s solution first. The short post only mentions it’s a solar LLM over Meshtastic using M5Stack hardware. On the left, we must have a power bank charge over USB (through a USB solar panel?) with two USB outputs powering a controller and a board on the right. The main controller with a small display and enclosure is an ESP32-powered […]
GoogleFindMyTools locates ESP32-based Bluetooth trackers using Google Find My Device network
Leon Böttger’s GoogleFindMyTools is a re-implementation of Google’s Find My Device network. It works with Android devices and commercial trackers, but experimental support for ESP32-based trackers has recently been added.
The implementation features two components. First, the main.py Python script that will list and locate devices, and then the ESP32 firmware implemented in C with the ESP-IDF. The host computer will also need several Python libraries that can be installed with “pip install -r requirements.txt” and Google Chrome web browser.
This is the output of the Python script on my Ubuntu laptop:
Queclink WR310 – A compact 5G and WiFi 6 industrial cellular router with four GbE ports, GNSS, and RS232 and RS485 interfaces
Queclink WR310 5G and WiFi 6 industrial cellular router features four gigabit Ethernet ports, a USB Type-A port, a terminal block with RS232 and RS485, and a wide 8 to 32V DC input suitable for smart manufacturing, industrial IoT (IIoT), and edge computing applications. It looks to be a more compact and cost-optimized version of the Queclink WR300 5G industrial router introduced in 2023 with global 5G coverage. The WR310 has many of the same features, but comes with less memory and storage, one less gigabit Ethernet port, and is available in three models depending on the region of operation: WR310FEU for EMEA, AP, and Brazil regions WR310FAU for LATAM markets WR310FNA for North America Queclink WR310 specifications: SoC – Unspecified Qualcomm dual-core Arm 64-bit Cortex-A53 @ 1.0GHz; likely the Qualcomm IPQ5018 or similar (Note the Qualcomm IPQ8072 quad-core Arm Cortex-A53 @ 2.2 GHz was used in the WR300 5G […]
