Arduino IoT Cloud Public Beta Launched

Arduino IoT Cloud Thing Widget

It’s long been possible to get data from sensors connected to official or compatible Arduino board, upload it to some cloud services, and watch the results is a neat web interface. But until now, you had to rely on third party services such as ThingSpeak, Adafruit.io, or Thinger.io to name a few. Arduino has now announced their own Arduino IoT Cloud services is entering public beta. You’d normally need to modify the sketch by hand to connect an Arduino board to the cloud, but Arduino IoT Cloud can automatically generate a sketch when setting up a new project, and help you get started quickly in less than five minutes. The Arduino IoT Cloud supports HTTP REST API, MQTT, Command-Line Tools, Javascript, and Websockets, and devices are secured using X.509 certificate-based authentication. To get started, you’ll need an Arduino MKR board, and create an account or login to Arduino IoT Cloud. […]

Google & Arduino Unveils the Arduino Science Kit Physics Lab

Arduino Science Kit Physics Lab

Google and Arduino have partnered together to developer and launch the Arduino Science Kit Physics Lab, the first official Arduino kit designed for middle school curriculum (ages 11 to 14). Based on Arduino WiFi MKR1010, the science kit will allow pupils to experiment with forces, motion, and conductivity, and log data with Google’s Science Journal “digital science notebook” app for Android. Arduino Science Kit Physics Lab kit content: Arduino MKR WiFi 1010 based on Microchip SAMD21 Cortex-M0+ MCU and Espressif Systems ESP32 WiSoC (WiFi + Bluetooth) Arduino Science Carrier Board 2x Silicone standoffs 1x Flat micro USB cable 1x Grove-compatible light sensor module 1x Grove-compatible temperature sensor module 1x Grove-compatible white LED module 3x Grove Cable 20cm – universal 4-pin connector 2x Double-ended cable: crocodile clip/banana plug (50 cm), 2x Double-ended cable crocodile clip/banana plug (20 cm) 1x Magnet 1x Hook-and-loop Velcro strap, 1x Hook-and-loop Velcro dot 2x PCB sticks, 1x […]

Allwize K2 IoT Board Supports 169MHz Wize LPWAN Protocol (LoRa alternative)

Allwize K2

LoRa, Sigfox, and NB-IoT are probably the most popular low power long range wireless protocols for the Internet of Things, but there are several others, including one I had never heard of: Wize. The Wize Low Power Wide Area Network (LPWAN) protocol has been created in late 2017, leverages the “old and refurbished” 169 MHz frequency, support up to 20 km range, 20-year battery life, and is managed by the Wize Alliance with members including STMicroelectronics, Suez, Sagecom, Renesas, Analog Devices, Silicon Labs and many others. Despite being a recent protocol, the table below claims 3 millions of deployment for Wize, and showcases some of differences against LoRa, NB-IoT, and Sigfox. You may be confused as how the standard was created in at the end of 2017, but there are so many deployments, and 13 years experience.  It appears Wize is derived from the older EN 13757 standard for gas […]

Tachyon Arduino Zero Compatible Board Features Microchip SAMD51 Arm MCU @ 120 MHz (Crowdfunding)

SAMD51 Arduino Board

Most Arm based Arduino compatible boards come with a Microchip SAMD21 Arm Cortex-M0+ MCU clocked at up to 48 MHz since this is the microcontroller found in the official Arduino Zero and MKRZero boards and comes with proper support in the Arduino IDE. But last year, Microchip introduced SAMD5x Arm Cortex-M4 microcontroller family  which offers devices that are pin-to-pin compatible with SAMA2x microcontrollers but with better performance, and more memory and storage. So the guys at Rabid Prototypes decided to make Tachyon, a tiny Arduino Zero compatible board based on SAMD51 MCU for people wanting more oomph out of their Arduino board. Tachyon board specifications: MCU – Microchip ATSAMD51G18A Arm Cortex M4F @  120 MHz with 256KB flash, 128 KB RAM I/Os Digital I/O pins – 14x w/ 12x PWM Analog input pins – 6x 12-bit ADC channels Analog output pins – 2x 10-bit DACs Operating voltage – 3.3V I/O […]

Exen Proto Arduino Compatible Board is based on Microchip SAMD21 MCU (Crowdfunding)

Nerdonic launched Exen Mini last year as the world’s smallest 32-bit Arduino compatible board, and getting the smallest board possible is very good for some projects, but so not much for other as Exen Mini is limited to just 8 I/O pins. So the company made another larger board called Exen Proto based on the same Microchip SAMD21 Cortex M0+ microcontroller, but offering more I/Os. Exen Proto specifications with difference against Exen Mini highlighted in bold: MCU – Microchip SAMD21 Cortex M0+ MCU @ 48 MHz with 256KB flash, 32KB SRAM I/Os via 2x 12-pin 2.54mm pitch headers Up to 20x digital I/O Up to 19x PWM Up to 11x analog (ADC) up to 12-bit resolution 2x UART Up to 5x I2C 1x reset Limits – 3.3V, 7mA USB – 1x micro USB port Programming – Via micro USB port or SWD header Misc – Power LED, user LED, button […]

NoCAN IoT Platform Leverages Raspberry Pi & Arduino for CAN Bus Projects (Crowdfunding)

Many IoT projects rely on wireless connectivity through WiFi or Bluetooth, but in some cases it may be more reliable and convenient to use wired connectivity. The CAN Bus is a little like a low bandwidth Ethernet PoE solution for IoT, as it allows to transfer data over a serial connection while provided power at the same time, and can be daisy chain to support multiple boards. Omzlo’s NoCAN IoT platform provides a CAN bus solution leveraging Raspberry Pi 3 board through their PiMaster HAT acting as a CAN bus gateway, and Arduino compatible CANZERO boards to which you can connect sensors and actuators. Omzlo PiMaster HAT specifications: MCU – STMicro STM32F042 Cortex-M0 32bit ARM MCU – 48Mhz. Networking –  125000 bps CAN bus up to 300 meters range GPIO – Communicates with Raspberry Pi through SPI + GPIOs Security – Smart power switch with over-current protection. Power Supply – […]

Arduino Introduces Two New IoT Boards – MKR WiFi 1010 (ESP32) and MKR NB 1500 (NB-IoT + eMTC)

MKR-NB-1500

Arduino introduced its MKR family of breadboard compatible maker boards with MKR1000 featuring an Atmel SAMD21 microcontroller combined with a Microchip WINC1500 WiFi module. The board was followed by MRKZero without wireless connectivity,  then MKRFOX1200 Sigfox board, and finally MKR WAN 1300 & MKR GSM 1400 boards at the end of 2017 with LoRaWAN and 3.75G cellular connectivity. The company has now launched two new boards: Espressif ESP32 based MKR WiFi 1010 with WiFi and Bluetooth, and MKR NB 1500 equipped with an NB-IoT & LTE CAT M1 module. Arduino MKR WiFi 1010 MKR WIFI 1010 is an evolution of the MKR1000 board, and is equipped with a U-Blox ESP32 module.
