Avnet Azure Sphere MT3620 Starter Kit Features Two mikroBUS Sockets

Microsoft and MediaTek worked together to design MediaTek MT3620 Arm Cortex-A7 processor with Microsoft Pluton security sub-system required for Microsoft Azure Sphere IoT ecosystem. We’ve already covered boards from Seeed Studio including the just announced low cost MT3620 mini dev board. But Microsoft also cooperated with Avnet which has recently introduced Azure Sphere MT3620 Starter Kit equipped with two mikroBUS sockets enabling the platform to leverage one of the 633 “click boards” available from MikroElektronika. Just like the latest Seeed Studio board, Avnet Azure Sphere MT3620 Starter Kit is comprised as a baseboard with a soldered-on CPU module that can later be used for mass-production is a custom designed board. Specifications: Azure Sphere MT3620 CPU Module Mediatek MT3620AN single core Arm Cortex-A7 processor @ 500 MHz with 4MB SRAM, dual core Arm Cortex-M4F real-time core @ 200 MHz with 64KB RAM, Microsoft Pluton security sub-system, and WiFi. Storage – TBD […]

Sub-$2 MH-Tiny ATTINY88 Micro Development Board Provides an Alternative to BluePill Board

Bluepill is a popular STM32 Arm Cortex-M3 development board in a compact form factor, and can be programmed with the Arduino IDE thanks to STM32duino project. A key selling point is also its ultra low price since it is now available for $1.67 including international shipping. I’ve now been informed a similar board is available, but instead of an STMicro MCU, it comes with Microchip ATtiny88 AVR micro-controller. We first discovered MH-Tiny ATtiny88 micro development board on Electrodragon where it is sold for $2.94, but the board is also listed on Aliexpress for virtually the same price as Bluepill board. MH-Tiny ATtiny88 micro development board specifications: MCU – Microchip ATtiny88 8-bit AVR MCU @ 16 MHz with 8KB ISP flash memory (over 6KB available after bootloader footprint taken into account), 64 bytes EEPROM, 512 bytes SRAM USB – 1x Micro USB port for power and programming Expansion – 2x 15-pin […]

ARBOR Introduces SOM-RP301 Rockchip PX30 SoM for Retail Kiosks

Rockchip PX30 is a quad core Cortex-A35 processor with a dual VOP (Video Output Processor) in order to drive two independent displays, that has low power consumption, low thermal requirements, and that we previously found in some car infotainment systems. But the processor is also suitable for other applications, and ARBOR Technology recently launched SOM-RP301 system-on-module based on the PX30 processor, and specifically designed for fanless retail kiosks such as electronic restaurant menus, automated currency exchange machines, ticketing kiosks and more. SOM-RP301 system-on-module specifications: SoC – Rockchip PX30 quad core Cortex-A35 processor @ 1.5 GHz with Arm Mali-G31 MP2 GPU System Memory – 1GB LPDDR3 (Up to 4GB as option) Storage – 16 GB eMMC flash Connectivity – Fast Ethernet transceiver, 802.11 b/g/n/ac WiFi 5 + Bluetooth 4.0 module Edge Connector – SO-DIMM connector with Display – LVDS or MIPI DSI Camera – MIPI CSI RX interface with 8MP ISP […]

Introducing CNX Election Meddling System

We love what we do at CNX Software, covering news, product launches, reviewing various types of boards and devices related to embedded systems. But we are also trying to expand our readers’ and our own horizon, always on the look out for unmet market needs that may be filled by the community at large. A few years ago, we found out that while democracy was all good, about people power and blah blah, it could create severe mental stress to the losing side, with talks of dark days for democracy, the end of the country as we know it, and so forth and so on. So we thought about ways to either help change the election outcome, at least lower the blow by making people feel they did the best they could possibly do beside just throwing a piece of paper in a box. That’s why we came up with […]

TB-96AI & TB-96AIoT are the First 96Boards Systems-on-Module

First introduced in 2015, 96boards specifications define mechanical, electrical, and software specifications for single board computers, but in 2017 Linaro asked companies to provide some feedback on what they’d like for a 96boards system-on-module standard. And for the first day of Linaro Connect Bangkok 2019, the 96Boards SoM specifications have now been announced, together with the introduction of Rockchip RK3399Pro powered TB-96AI and Rockchip RK1808 based TB-96AIoT, the first compliant 96Boards SoMs, and corresponding 96Boards SoM Carrier Board. 96Boards System-on-Module Specifications Two 96Boards SoM specifications have been unveiled with the Compute Module Specification and the Wireless Specification. The 96boards Compute Module Specification defines a SoM with up to four 100-pin connectors, but only one is mandatory (X1), and two form factors are specified: SOM-CA (85 x 50 mm) and SOM-CB (50 x 50 mm). List of signals associated to each connectors: X1 – SoM managements, 1x UART, 2x I2C, 1x […]

ClearFog ITX Workstation May be the Ultimate Arm Developer Platform

Most people are still doing Arm development work on x86 platforms, because there aren’t really any viable equivalent in the Arm world. Current options include Edge Server SynQuacer E-Series (aka Linaro Developer Box), a $1,250 Arm PC shipping with a 24-core Arm Cortex-A53 processor, 4GB RAM (by default), a 1TB hard drive, and Geforce GT710 graphics cards, as well as the much more powerful GIGABYTE ThunderXStation workstation with up to two Cavium ThunderX 32-core Armv8 processors, 32GB to 128GB RAM configuration, NVMe storage, and more. The former was a good place to get started, but the Arm Cortex-A53 cores clicked at 1GHz provided limited performance, and the GIGAGYTE workstation costs over $12,000, so it’s only suitable for projects with specific needs and/or a high expected return on investment. That’s why there will be a discussion about Designing a next generation ARM Developer Platform at Linaro Connect 2019 next week in […]

Pyboard D-series Wireless Micropython Boards Launched for $56 and Up

We’ve already mentioned the latest Pyboard D-series board at the beginning of February after it was introduced at FOSDEM 2019. The board comes with a powerful STM32F7 Arm Cortex-M7 microcontroller, as well as a WiFi and Bluetooth wireless module. The news is that the board has now launched for £43.80 in.c VAT ($56) and up. A better price comparison with other boards is normally achieved by comparing the ex. VAT price of £36.50 or about $48. That may still feel a bit pricey to some, but there was enough interest to snatch all available “PYBD-SF2-W4F2” boards, and this specific board is out of stock at the time of writing. However, there are multiple variants of the board and PYBD-SF3-W4F2 is still in stock for £58.20 inc. VAT (~$76.5). We’ve now got the full Pyboard D-series “PYBD-SF2-W4F2” specifications: MCU – STMicro STM32F722IEK Arm Cortex M7 microcontroller at 216 MHz with 256KB […]
