Elecrow develops and manufactures electronics products for the maker market, and in recent years entered the STEM education market with products such as CrowPi2 Raspberry Pi 4 education laptop that I reviewed last year. The laptop integrates plenty of electronics modules, and students can learn Scratch visual programming as well as Python programming with the educational software running on the laptop. The company has now launched Crowbits magnetic electronic blocks for STEM education, and compatible with Arduino, ESP32, Raspberry Pi, and Micro:bit boards. There are over 80 programmable electronic magnetic modules and Lego bricks, with three different sizes ( large, middle, and small modules) of different colors with blue used for power control and logic control, green for output, yellow for input, and orange for advanced programming. Out of the 80+ modules, around 30 can be used without programming at all. Elecrow provides 5 kits to let users learn basic electronics and programming knowledge, namely the Hello Kit designed for […]
Nordic Semi nRF91-series of Cortex-M33 SoCs with NB-IoT and LTE-M (eMTC) cellular IoT connectivity was first unveiled in 2018. The first member of the family is nRF9160 System-in-Package (SiP) which also comes with GPS, and we’ve found it Nordic’s own Thingy:91 devkit, as well as in various modules and development boards from third parties. There’s now a new kit called Pebble Tracker that features Nordic Semi nRF9160 with NB-IoT, LTE-M, and GPS connectivity, as well as environmental, motion, and light sensors.

MicroMod is a modular interface ecosystem for quick embedded development and prototyping. MicroMod comes with two components, that is a microcontroller “processor board” and a carrier board. PC industry’s M.2 connector is the interface between these two components. The carrier boards are for the usage of various peripherals and the processor board act as the brain of the application system. MicroMod processor board has a dimension of 22×22 mm that can be easily fitted on the carrier boards. Although, the original M.2 standard was dedicated to swapping out peripherals where a user could swap one component with the other one. The MicroMod standard is for swapping out microcontrollers according to the functional and application requirements. MicroMod Processor Boards Artemis Processor Board comes with an Ambiq Apollo 3 Blue Arm Cortex-M4F with BLE 5.0 running up to 96MHz and a power rating of less than 5mW. It also supports the TensorFlow Lite framework. ESP32 Processor Board comes with a dual-core Tensilica […]
Last year, Actinius launched Icarus IoT Board equipped with nRF9160 SiP providing GPS & NB-IoT connectivity in Adafruit Feather form factor. The company is now back with more compact Nordic Semi nRF9160 hardware, namely the tiny 28×18.5mm Icarus SoM with built-in eSIM, as well as Icarus Bee XBee module that incorporates Icarus SoM plus a nano-SIM slot, as well as an RGB LED and a user button. Icarus SoM The module comes with the following specifications: SiP – Nordic Semi nRF9160-SICA system-in-package with Arm Cortex-M33 MCU, 1024 KB flash, 256 KB SRAM, and LTE-M (eMTC), NB-IoT, and GPS connectivity Storage – 64Mbit SPI flash On-board eSIM Antennas – 2x u.FL connectors for LTE and GPS Sensor – Accelerometer I/Os – 2x 20 castellated holes with GPIOS, I2C, SWD, Reset, SIM card signals, and power pins Supply Voltage – 3.3V Dimensions – 28 x 18.5 mm The multi-layer module is designed to help customers simplify their design and bring products faster […]
If you’re developing battery-powered products it’s important to optimize your application to consume as little power as possible to extend battery life. As we’ve seen with Qoitech Otii Developer Tool, getting the right tool for development can help developers work more efficiently, and save countless man hours. If you’re specifically working on products based on Nordic Semi nRF51, nRF52, nRF53 or nRF91 wireless chips, the company has just announced the Power Profiler Kit II (PPK2) that enables easy and affordable power measurement of average and dynamic power consumption in embedded solutions based on the aforementioned wireless SoC’s/SiP’s. Power Profiler Kit II key features: 200nA to 1A measurement range Resolution varies between 100nA and 1mA depending on the measurement range Instantaneous and average current measurement for all Nordic DKs, in addition to custom HW Ampere meter and source modes Built-in programmable regulator with a 0.8V to 5V output range and up to 1A current supply 100 ksps sampling rate, or 10x […]
The original BBC micro:bit educational board was launched in July 2015 with a Nordic nRF51822 Arm Cortex-M0 MCU @ 16 MHz providing Bluetooth LE connectivity, a few I/Os, some buttons, and a LED matrix acting as a small display. The British company has now launched a new update with BBC micro:bit v2 with the same form factor, but equipped with a more powerful Nordic Semi nRF52833 Bluetooth 5.1 Arm Cortex-M4 MCU clocked at 64 MHz and adding a microphone and a speaker.

Rakwireless has launched several IoT evaluation boards such as RAK4260 LoRaWAN EVB relying on WisBlock modules comprised of a carrier board and a module. So far, those were always sold as part of evaluation boards, but now the company is trying to expand WisBlock use as a modular system, so users can easily build their custom systems, LEGO style. The modular system is based on four different block types: WisBlock Base – A carrier board with connectors for other block types, power supply, some ports WisBlock Core – Module with a microcontroller/processor WisBlock Sensor – Modules with environmental sensors, motion sensors, ambient light sensors, or others WisBlock IO – Adds more inputs, outputs, or connectivity options including LTE-M / NB-IoT, cellular and Wi-Fi modules, NFC reader, and interfaces for I2C, UART, ADC, and GPIO. The company is just getting started with the solution, and initially will be offering one WisBlock baseboard, an improved version of the one used with RAK4260 […]
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.
