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. BBC micro:bit v2 specifications: Wireless MCU – Nordic Semi nRF52833 Arm Cortex-M4 MCU clocked at 64 MHz with 128 KB RAM, 512 KB flash, Bluetooth 5.1 LE connectivity “Display” – 25x red LED indicator lights in a 5×5 matrix USB – 1x micro USB port for power and programming via NXP Kinetis KL27Z Cortex-M0+ microcontroller Audio – Built-in MEMS microphone and speaker Expansion 25 pins on edge connector with 4 dedicated GPIO, PWM, I2C, SPI etc… 5x rings […]
During Embedded World 2020 (EW2020), some companies withdraw their presence, while some were at the event. MikroElektronika presented several new boards and among them Fusion for ARM v8 and EasyPic v8 development boards. While we already wrote about Fusion fo TIVA, we haven’t covered any EasyPic board yet. Development boards from MikroElektronika allow rapid prototyping in the most efficient and effortless way. Fusion for ARM v8 Fusion for ARM v8 belongs to the Fusion family of development boards. It has integrated the world’s first embedded debugger/programmer over WiFi, while the CODEGRIP WiFi license is available as an add-on feature. The board is designed to be used in almost every environment retaining full debugging and programming access. The CODEGRIP currently supports more than 1600 microcontrollers from different vendors. The Fusion board integrates a new MCU card standard. It is a low profile standard where sockets consist of two connectors (male/female) which prevents the wrong insertion. The MCU card has standardized dimensions […]
Arm TechCon will take place on October 8-10, 2019 at San Jose Convention Center to showcase new solutions from Arm and third-parties, and the company has now published the agenda/schedule for the event. There are many sessions and even if you’re not going to happen it’s always useful to checkout what will be discussed to learn more about what’s going on currently and what will be the focus in the near future for Arm development. Several sessions normally occur at the same time, so as usual I’ll make my own virtual schedule with the ones I find most relevant. Tuesday, October 8 09:00 – 09:50 – Open Source ML is rapidly advancing. How can you benefit? by Markus Levy, Director of AI and Machine Learning Technologies, NXP Over the last two years and still continuing, machine learning applications have benefited tremendously from the growing number of open source frameworks, tools, and libraries to support edge inferencing. These include CMSIS-NN, ARM […]
The new Arrow ASME Tiger board is the latest addition to the ASME line up, with an eye towards IoT hardware prototyping. The board carries two MCUs for different types of development depending on the operators need. The board is Thread and WiFi ready, and the Tiger is also Arduino compatible. The MCU’s are as follows: The ATSAMD21J18A-64 Ultra-low-power microcontroller using the 32-bit ARM Cortex-M0+ processor. The WiSoC is the KW41Z which is an ultra-low-power, highly integrated single-chip device that enables Bluetooth® low energy (BLE) v4.2 and IEEE® 802.15.4 RF connectivity for portable, extremely low-power embedded systems. The working unit is for very low power applications. The integrated balun reduces system cost and board area, and the sensors are plentiful and easy to access. You’ll find a user guide (PDF), as well a bootloader and sample code on Github. Specifications for the SMART SAMD21 Memory 256KB in-system self-programmable Flash 8KB Flash Read-While-Write section 32KB SRAM Main Memory 8KB SRAM Low […]
OpenISA has launched an Arduino compatible RISC-V development called VEGAboard that features RV32M1 wireless microcontroller with a RISC-V RI5CY core, a RISC-V ZERO-RISCY core as well as Arm Cortex-M4F and Cortex-M0 cores, and a radio operating in the 2.36 GHz to 2.48 GHz range. An external NXP Kinetis K26 Arm Cortex-M4 MCU is added to the board for OpenSDA (Open-Standard Serial and Debug Adapter) debugging over a single USB cable. The board was offered for free, I’m just not sure when, but they are already out of stock. Hopefully, they’ll start selling the board soon enough. VEGAboard (RM32M1-VEGA) board key features and specifications: Ultra-low-power RV32M1 Wireless MCU supporting BLE, Generic FSK, and IEEE Std 802.15.4 (Thread) platforms IEEE Std. 802.15.4-2006 compliant transceiver supporting 250 kbps O-QPSK data in 5.0 MHz channels, and full spread-spectrum encoding and decoding Fully compliant Bluetooth v4.2 Low Energy (BLE) Reference design area with small-footprint, low-cost RF node: Single-ended input/output port Low count of external components […]
South Korea based Sigma Delta Technologies’ SDTxArm Pelion Kit is a modular development kit comprised of a baseboard, as well as CPU and interface modules that is specifically designed to work with Arm Pelion cloud based device management service and Mbed OS for wearables and IoT applications.

The industry clearly has an issue at hand with the security of the Internet of Things, and the problem is complex as some devices are easily accessible due to bad configuration (e.g. default username/password), while others may have security flaws at various levels of the software stack from the low level bootloaders to the operating systems, and applications. Nowadays, devices also need to be upgradeable, and communicate with the cloud, and that introduces other attack vectors in case malignant firmware is installed instead, or a man-in-the-middle attack occurs. While some people may claim security can be achieved by software only, we are seeing security evolving towards combined software and hardware solutions, for example with Arm Trustzone built into SoCs, but some companies are also introducing Secure Element chip, which Samsung has already done and integrated into their Artik modules to secure data from the hardware to the cloud. NXP has now also launched their own A71CH Secure Element (SE), described […]
Atomo is a modular electronics protyping system comprised of four elements: Control, I/O, Power, and Connector, with the PCBs for each category color-coded with respectively red, blue, green, and black. The connector board connects power, I/O and control(ler) boards together in a way that’s supposed to be neater than most hand made prototypes. The whole ecosystem includes 15 different boards: Controllers with 26-pin Raspberry Pi compatible header 2 IO Module Controller (CM-M2K22-A) based on NXP Kinetis K22F MCU 4 IO Module Controller (CM-M4K64-A) based on NXP Kinetis K64F MCU 8 IO Module Controller (CM-M8K64-A) based on NXP Kinetis K64F MCU Connectors 8 IO Module Connector (GM_M8P2_A) – Dim: 145mm x 100mm; power up to 40V @ 64A 4 IO Module Connector (GM_M4P1_A) – Dim: 71mm x 100mm; power up to 40V @ 32A 2 IO Module Connector (GM_M2P1_A) – Dim: 71mm x 65mm; power up to 40V @ 16A 2 IO Module Low-Power Connector (GM_M2P0_A) – Dim: 71mm x 65mm; Good for low power […]
