QuickDAQ.mikroBUS Development Board Leverages Visual Programming and MikroE Click Boards (Crowdfunding)

Virtuoso Visual Programming

mikroBUS is a socket interface that allows you to connect MikroElektronik (MikroE) Click add-on boards that can be buttons, sensors, a servo controller, a wireless module, and practically anything you may think of since there are over 700 Click boards to choose from. We already covered several SBC with MikroBUS sockets starting with SolidRun HummingBoard Gate board that offered a single socket for 150+ Click boards at the time (2015). Other boards include Azure Sphere MT3620 with two MikroBUS sockets and MikroElektronika’s own Flip & Click board designed to take one Arduino shield and up to four Click boards. Another upcoming option is QuickDAQ.mikroBUS developer by EmbeddeTech in collaboration with MikroElektronika, powered by a Microchip PIC32 MCU, offering three MikroBUS sockets, and designed to work with “Virtuoso Low-Code Environment” that allows people to program the board using NodeRed-like visual programming and generate a Visual Studio project with code from the […]

BOKRA NXP LPC824 and Nordic nRF52832 powered MCU Modules Follow MikroBUS Form Factor

We first wrote about MikroElectronika MikroBUS socket in 2015 while covering an SBC which featured one MikroBUS socket supporting one of the 150 Click boards available at the time. There are now over 700 Click boards to choose from, with the tiny modules offering motor drivers, buttons, short-range connectivity,  UART and other interfaces, as well as various sensors. But BOKRA had another idea: developing MCU based systems-on-module following MikroBUS form factor. BOKRA LPC824 Lite module The first of those modules is BOKRA LPC824 Lite with the following specifications: MCU – NXP LPC824M201JHI33 Arm Cortex-M0+ microcontroller @ 30 MHz with 32KB Flash Memory, 8 KB RAM I/O MikroBUS headers with SPI, I2C, UART, PWM, GPIOs 10-pin “Serial” header 4-pin I2C Grove connector for Seeed Studio I2C Grove modules Debugging interface – SWD Misc – Reset button, power LED, 2x user LEDs Power Supply – 5V/500mA via MIC5528 regulator Dimensions – 28.6 […]

Programmable USB Hub Power Adjustable with Built-In Dev Board (Crowdfunding)

Capable Robot Components has launched its Crowd Supply campaign for the Programmable USB Hub in June of 2019. The hub is a feature rich and component rich USB hub that has a dev board built-in. The entire system is housed in an extruded aluminum case, with all the numbering and lettering and port attachments in brilliant white.  Control power and data flow, directly through the unit. The first 40 units are sold out. There seem to be good reasons why these USB Hubs sell out fast.  There was an in-depth article written on a similar hub some time ago.  Inside the enclosure is an array of functionality packed neatly onto a small board. There are 4x USB 2.0 ports that are High-Speed downstream ports and 1x upstream port, a 5th endpoint on the USB hub exposes 2 12C buses via Sparkfun Qwiic connectors, the UART and 2X GPIO. The input power is […]

Amazon FreeRTOS Released for NXP, Texas Instruments, STMicro, and (soon) Microchip Microcontrollers

FreeRTOS is an open source real-time operating system for microcontrollers released under an MIT license, and when it comes to adoption in embedded systems it’s right there near the top with embedded Linux according to Aspencore 2017 embedded markets study. For example, some Espressif SDKs for ESP8266 or ESP32 are based on FreeRTOS, and so is Mediatek LinkIt Development Platform for RTOS. The recently announced Amazon FreeRTOS (a:FreeRTOS) leverages the open source operating systems, and extends it with with libraries that enable local and AWS cloud connectivity, security, and soon over-the-air updates. a:FreeRTOS is free of charge, open source, and available today. In order to get started, you’ll have a choice of 4 hardware platforms: STMicro STM32L4 Discovery Kit IoT Node (B-L475E-IOT01A) powered by STM32L475 ARM Cortex-M4 MCU with 802.11 b/g/n WiFi, Bluetooth 4.1 LE, RF (868 / 915 MHz), and NFC connectivity, plenty of sensors NXP LPC54018 IoT module (OM40007) […]
