Sparkfun’s Pulsed Coherent Radar Sensor features Acconeer XM125 60 GHz module, works through walls, offers up to 20-meter range

SparkFun Pulsed Coherent Radar Sensor Acconeer XM125 Qwiic

SparkFun has launched a new Qwiic breakout board for the Acconeer XM125 60 GHz pulsed coherent radar sensor that can measure distance to humans even through walls and works at a distance of up to 20 meters. We’ve seen tiny 24GHz or 60GHz radar modules for several years now, and Supachai even reviewed the Seeed Studio mmWave sensor using ESPHome and Home Assistant late last year with the solution relying on Frequency-Modulated Continuous Wave (FMCW) technology. The Acconneer XM125 is a Pulse-radar module that emits electromagnetic waves in short bursts instead of continuously like FMCW radars and allows longer measurement ranges potentially at the cost of lower accuracy. Sparkfun Pulse Coherent Radar Sensor specifications: Acconeer XM125 Module A121 60GHz Pulsed Coherent Radar (PCR) Integrated baseband, RF front-end, and antenna in package Detects distance, speed, motion, and objects up to 20 meters away Millimeter precise readings Low power consumption STMicro STM32L431CBY6 […]

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 […]

SparkFun launches MicroMod Single Pair Ethernet kit for easier 10BASE-T1L experimentation

The SparkFun MicroMod Single Pair Ethernet Kit utilizes the ADIN1110 transceiver for 10BASE-T1L communication, enabling long-distance connectivity over a single twisted pair cable. Things get easier as SparkFun has designed the module to be compatible with the MicroMod ecosystem, which allows for testing connections between industrial devices over long distances, up to 1,700 meters. The standout feature of this board is its ADIN1110 transceiver, which supports 10BASE-T1L Ethernet. This technology uses a single twisted pair for lightweight, long-distance data transmission, achieving speeds up to 10Mbps by the 802.3cg IEEE standard, all without delivering power over the cable. SparkFun MicroMod Single Pair Ethernet Kit Specification: 2x SparkFun MicroMod Single Pair Ethernet Function boards 10BASE-T1L IEEE Standard 802.3cg-2019 Compliant Transceiver Single-pair Ethernet transmission at speeds up to 10Mbps 1km transmission distance (1.7km max cable reach) Supply Voltage of 1.8V or 3.3V 2.4V transmission amplitude Integrated MAC connects via SPI – Supports 16 MAC addresses Supports both […]

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 […]
