IoT development board comes with AVR or PIC MCU, WiFi module

AVR-IoT and PIC-IoT Development Boards

Microchip AVR-IoT and PIC-IoT development boards have AVR and PIC MCUs respectively, which enables a simple interface between embedded applications and the cloud. The IoT development boards can securely transfer data to Amazon Web Services (AWS) IoT platform with a WiFi connection. The IoT development boards also include an onboard debugger which can be used to program and debug the MCUs without any need for external hardware. The IoT development boards also have an integrated lithium battery charger, which makes it a rechargeable device and allows easier deployment for a “ready-to-go solution.” The AVR-IoT WA development board integrates the ATECC608A CryptoAuthentication chip for security protocols and the ATWINC1510 Wi-Fi network controller for connectivity. The development board combines the ATmega4808 MCU 8-bit AVR MCU running at up to 20 MHz and offers a wide range of flash sizes up to 48 KB. The unit uses a “flexible and low-power architecture, including Event System and SleepWalking, accurate analog features, and advanced peripherals.” […]

CodeBug Connect IoT development board is designed for young makers (Crowdfunding)

CodeBug Connect Development Board

In 2015, a UK-based team launched a mini IoT development board called CodeBug. The same team has now come up with the CodeBug Connect IoT Development Board.  CodeBug Connect is a new wearable micro-computer that brings IoT to everyone and aimed at educators and young makers.  Upgrade to the original CodeBug This comes as an upgrade to the original CodeBug. The new development board retains its original cuteness and petite proportions but adds full color to the grid of 5×5 LEDs. The original buttons have been upgraded to mini joysticks, making them more suitable for games. The touch-sensitive, croc-clip connectors ‘legs’ that serve as I/O pins remain, as does the 0.1” header socket. “This year has shown our reliance on connected technology — with CodeBug Connect we wanted to make this technology accessible so everyone can build their own IoT devices and no one is left behind. The technology in our original CodeBug has been used by over a million […]

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 visual representation. QuickDAQ.mikroBUS hardware specifications: MCU – Microchip PIC32 microcontroller […]

MikroElektronika Launches Fusion for ARM & EasyPic MCU Development Boards

fusion for arm

During Embedded World 2020 (EW2020), some companies withdrew 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 […]

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) based on LPC54018 Arm Cortex-M4 core @ 180MHz with Longsys […]

Detect Lightning with Those AMS AS3935 “Thunder” Boards

Launched in 2012, AMS AS3935 Franklin lightning sensor  is – at its name implies – a lightning sensing IC. The chip was designed for low power, portable or fixed wire-line applications, and beside detecting electrical emissions from lightning activity, it can also provide an estimation of the distance to the head of the storm from 40km away down to 1km, while filtering out other signals from motors, microwave ovens, etc… The chip interfaces via SPI or I2C to the host processor / micro-controller, and comes in a small MLPW-16 (4x4mm) package. Price is $3.55 per unit for 1k orders. Applications include wearables, golf carts, pool safety, portable GPS, bike computers, weather stations, uninterruptible power supplies, smart grid systems, environmental monitoring systems, etc… Basically, AS3935 can be used either for weather monitoring, or safety applications. I’ve found two maker boards with the chip: MikroElectronika Thunder Click board compatible with MikroBUS socket (available now), and SwitchDoc Labs Thunder Board recently launched on […]
