u-blox unveils miniature MIA-M10 GPS module

u-blox has introduced what could be the world’s smallest GNSS module with the 4.5×4.5mm u-blox MIA-M10 miniature module supporting GPS, BeiDou, Galileo, and GLONASS satellite navigation systems. The MIA-M10 is said to be about half the size of competing products and has been specially designed for size-constrained battery-powered asset tracking devices, as well as space-constrained industrial sensors and consumer goods. The company also claims its power-save modes can double the battery life by balancing position accuracy and power consumption. u-blox MIA-M10 GNSS module specifications: GNSS – BeiDou, Galileo, GLONASS, GPS / QZSS Number of concurrent GNSS – 4 Oscillators MIA-M10C – Crystal MIA-M10Q – TCXO MIA-M10Q only – SAW filter, LNA Host Interfaces – 1x UART, 1x DDC (I2C compliant) Supply Voltage MIA-M10C  – 1.3 to 1.98V MIA-M10Q – 1.76V to 3.6V Power Consumption – < 25 mW Dimensions – 4.5 x 4.5 x 1.0mm Temperature Range – -40°C to […]

Unsurv offline – An ESP32 GNSS receiver board with NFC, accelerometer (Crowdfunding)

Unsurv offline is a compact and lightweight board with ESP32 WiSoC, a GNSS receiver, an accelerometer, and NFC capabilities to help developers/users collect and analyze location data in a privacy-friendly way. Unsurv Technologies initially developed the board to better understand offline video surveillance with OpenStreetMap (OSM) data. It does so by using a database of camera locations from the OSM on the SD card, “counts” surveillance cameras as you walk past them, and you can then transmit data via NFC and visualize it on your smartphone. The accelerometer is used to wake up the board from deep sleep upon detection of motion. The company has now made the board open-source and other applications are also possible. Unsurv offline specifications: Wireless modules TTGO T-micro32 WiFi 4 and Bluetooth 4.2 module based on ESP32-PICO-D4 SiP with dual-core ESP32 processor, 4MB FLASH, ceramic antenna U-blox CAM-M8C (aka u-blox M8) module with concurrent reception […]

simpleRTK2B-SBC packs 3 u‑blox ZED-F9P RTK GNSS receivers for centimeter-level GPS positioning

Real-time Kinematic (RTK) relative positioning technique allows for 1-3cm positioning accuracy with data derived from satellite-based positioning systems such as GPS, BeiDou, GLONASS, Galileo, and NavIC. We’ve previously covered Skytraq PX1122R RTK GNSS module as well as SBG Systems Ellipse-D industrial-grade inertial navigation system featuring the technology, and now Spain-based ArduSimple has announced the simpleRTK2B-SBC single board computer that aims to “simplify the development of centimeter-level positioning solutions supporting real-time kinematics (RTK)” via up to three u‑blox ZED-F9P RTK GNSS receivers. simpleRTK2B-SBC board features & specifications: MCU – STMicro STM32F7 Cortex-M7 microcontroller GNSS Positioning 184-channel u-blox ZED-F9P engine Configuration options 2x ZED-F9P for position + heading 3x ZED-F9P for position + full attitude (roll, pitch, yaw) Navigation rate up to 20Hz Position accuracy down to 1 centimeter GPS: L1 & L2;  GLONASS: L1OF & L2OF;  Galileo: E1 & E5b;  BeiDou: B2I & B2I; QZSS and SBAS Up to 4 integrated […]

SODAQ SARA is an Arduino Compatible Cellular IoT Board with LTE-M, NB-IoT, and GNSS (Crowdfunding)

There really seems to be a push for cellular IoT those days, with new hardware coming up every week.  Following up on their NB-IoT shield for Arduino last year, SODAQ has now launched two versions of SARA boards based on u-blox SARA LTE-IoT modules, and u-blox M8Q GPS/GNSS module. Both boards are Arduino compatible thanks to a Microchip SAMD21 MCU, and while u-blox SARA board follows the Arduino form factor, u-box SARA SFF is much more compact (50×25.4 mm) and potentially easier to integrate into a project or product. Another pretty unique feature (AFAICT) is that you can power the board directly with a solar panel. u-blox SARA board specifications: Wireless module (three options) with external antenna: SARA-N211 NB-IoT, band 8 and 20, for the European and African market SARA-R410M Dual mode LTE-M and NB-IoT module for all global bands SARA-R412M Triple mode module with LTE-M, NB-IoT and 2G for […]

U-blox SARA-R410M-02B Module Supports LTE Cat M1 and Cat NB1 in a Single Package

We previously covered U-blox SARA-R4 LTE Cat M1 and SARA M2 NB-IoT (Cat NB1) modules, but in case you need support for LTE Cat M1 and Cat NB1, instead of just one or the other, in your product, U-blox launched a new SARA-R4 model with SARA-R410M-02B module supporting both standards. U-blox SARA-R410M-02B module specifications: LPWAN connectivity LTE Cat M1 Half-duplex: 375 kb/s DL and UL LTE Cat NB1 Half-duplex: 27.2 kb/s DL, 62.5 UL Shared bands – 1, 2, 3, 4, 5, 8, 12, 13, 17, 18, 19, 20, 25, 26, 28;  Cat M1-only band – 39 Coverage enhancement Mode A and Mode B (in upcoming firmware), 3GPP Rel 13 e-DRX  (Extended Discontinuous Reception) supported in upcoming firmware SMS support – MT/MO PDU / Text mode; SMS over SG/NAS Voice – VoLTE (Cat M1) using AMR-WB codec (U)SIM supporting 1.8 and 3V GNSS/GPS support with CellLocate and Hybrid positioning coming […]

u-Blox Unveils SARA-R4 LTE Cat M1 and SARA-N2 NB-IoT Modules for Professional IoT Applications

While I’ve mostly read about SigFox and LoraWan solutions for long range, low power, and low bitrate communications for the Internet of Things so far, there are many active of planned LPWAN standards for IoT applications, and 3GPP Release 13 standard stipulates two LTE LPWAN standards, namely LTE Cat M1 (eMTC) and LTE Cat NB1 (NB-IoT), with the former  supporting 1 Mbps downlink and uplink peak data rates, and the latter 250 Kbps downlink, and 250 Kbps (multi-tone) or 20 Kbps (single tone) uplink data rates. U-Blox has released modules for both standard with SARA-R4 LTE Cat M1  and SATA-N2 NB-IoT modules. SARA-N2 Cat NB1 cellular module specifications: LPWAN Connectivity – 3GPP Release 13 NB1; NB-IoT bands: 5, 8, 20; downlink: 227 Kbps, uplink: 21 Kbps Positioning – GNSS via Modem Interfaces – 1x UART, 1x SPI, 2x GPIO, 1x DDC(I2C) for GNSS Features – Antenna supervisor, embedded IPv4 & […]

Sparkfun launches cheaper no-code “DataLogger IoT” board compatible with Qwiic modules

Last May, SparkFun introduced the “Datalogger IoT – 9DoF” no-code platform with support for over 50 Qwiic sensor modules and a built-in 9-axis IMU sensor and magnetometer. Taking into consideration that some users may not make use of the built-in sensors, the company decided to launch a cheaper version called the “DataLogger IoT” that can still get data from Qwiic sensor and GPS modules without any programming thanks to the “no-code” Arduino firmware preloaded on the ESP32-WROOM-32E module. SparkFun DataLogger IoT specifications: Wireless module – ESP32-WROOM-32E with: ESP32 dual-core microcontroller 4MB flash 2.4 GHz WiFi and Bluetooth LE connectivity, built-in PCB antenna Storage – MicroSD card slot USB – 1x USB Type-C port for power and configuration via CH340C Expansion – 2x Qwicc I2C connectors for sensors and/or GPS module Misc Boot and Reset buttons Status and charging LED, WS2812 RGB LED Jumpers to enable/disable LEDs, I2C pull-up resistors, and […]
