Teensy 4.0 Launched for $20 with a Much Faster NXP i.MX RT1062 Arm Cortex-M7 Processor

We last wrote about Teensy boards in 2016 for the launch of Teensy 3.5 & 3.6 boards powered by NXP Kinetis K64/K66 Arm Cortex-M4 microcontroller, and a longer form factor. Paul Stoffregen has now upped the ante with Teensy 4.0 featuring a much more powerful NXP i.MX RT1062 Cortex-M7 cross-over processor clocked at 600 MHz, and going back to the original, and more compact, form factor of earlier Teensy boards such as Teensy 3.2. Teensy 4.0 hardware specifications: SoC – NXP i.MX RT1062 Arm Cortex-M7 processor at 600 MHz with 1024KB RAM (512KB is tightly coupled), Storage – 2048KB serial flash (64KB reserved for recovery & EEPROM emulation) USB – 1x micro USB port for power and programming Expansion via through-holes and pads USB – 2x USB ports, both 480 MBit/sec Storage – 1x SDIO (4 bit) native SD Audio – 2x I2S Digital Audio, 1x S/PDIF Digital Audio Serial […]

UnaMKR Sigfox Monarch Development Kit Follows Arduino MKR Form Factor

Unabiz is an IoT network operator with offices in Singapore and Taiwan. The company offers Sigfox networks in the region, and last year unveiled UnaMKR, a Sigfox Monarch development kit compatible with the tiny Arduino MKR boards. We’ve already written about Sigfox LPWAN standard several times, but what is Sigfox Monarch exactly? Answer direct from Sigfox website: The Monarch feature makes IoT devices aware of the local radio configuration (RC) to use. A single device can thus lawfully communicate on the Sigfox network even when moving between countries with different radio regulations. That means a Sigfox Monarch compliant end-point can work legally anywhere in the world switching to 868 MHz, 902 MHz, and 920 MHz frequencies automatically depending on the country of operation. This is useful for asset tracking across countries and continents. Back to the board itself, with UnaMKR specifications: Platform – Arduino or STMicro Connectivity Lite-On WSG309S Sigfox […]

easySwitchBox is a LoRa Wall Switch Powered by Coin Cell Batteries and Arduino (Crowdfunding)

easySwitchBox is a simple actuator that does one basic thing – To send an on/off signals that can be used to control anything wirelessly. Whatever you intend on doing with the signal sent is left to you. easySwitchBox is the brainchild of easySensors, the Belarus based creators of DIY Arduino focused hardware products. easySwtichBox combines an Arduino based chip and a LoRa radio to be able to send a signal for long-range distances. On the surface, easySwitchBox looks like another wall switch you have seen around, but there is more to it. Powered by the famous Atmega 328P microcontroller, easySwitchBox is more than a wall switch, and you can reprogram it to be an intelligent one indeed or anything else you want. The power supply comes from two attached coin cell battery, making it possible to move the device around and not be confined by location or space. easySwitchBox […]

Elk, An Allwinner H3 Development board Crafted For the Decentralized Internet (Crowdfunding)

Elk: The Dev Board for the Decentralized World

Back in 2017, Bitcoin peaked at almost $20,000; many were pretty shocked about how this supposed virtual currency suddenly become a scare resource. It also brought limelight to the technology behind it Blockchain and the idea of Decentralized internet. Although the success of the cryptocurrency didn’t last that long, as it lost about 80 percent in a year and still categorized as one of the biggest bubbles in financial history. After the crash of Bitcoin and some other similar cryptocurrencies, a lot of people predicted that’s the end of the whole Blockchain thing, and the idea of Decentralized internet will not happen. The recently announced Facebook Libra, a new cryptocurrency by the American giant Facebook, shows that Blockchain and the Decentralized web isn’t going anywhere and will probably start growing stronger. Arduino made it possible for Artist, Makers, Engineers, Students to bring ideas to life and quickly make things easier. Now, […]

Arduino based Clover Platform Targets STEM Education in Vietnam

We’re already seen there’s an active maker community in South East Asia with products such as KidBright32 educational board in Thailand, and Singapore & Thailand based MakerAsia’s recent launch of the open-source KB-IDE for ESP32 targets. Vietnam based Clover Team also introduced a STEM platform for students late last year with hardware, an IDE, and a mobile application. The team has made three educational kits: Clover EDU Basic with Clover Master Board and basic modules Clover Car Robot with Clover Master Board, motor, motor driver module, line sensor, distance sensor, Bluetooth module Clover Inventor that includes all items from Clover EDU Basic and Clover Car Robot plus a WiFi module. The Master board is compatible with the Arduino UNO platform (software-wise) and comes with the following key features: Connectivity – Header for ESP8266 WiFi module Expansion – 4x RJ11 ports for input and output with color signs, and compatible with […]

$6.90 Seeeduino Nano Board | Compatible With Arduino Nano

Seeed Studio has announced the release of yet another compact board. The new board, Seeeduino Nano, is quite similar to the Arduino Nano board, and fully compatible. Another thing about the new board is that it has some different features. Seeeduino Nano comes with only one on-board Grove connector, but it can be expanded with the optional Grove shield adding 8 Grove connectors. More precisely, the shield has 3 Grove digital connectors and 3 Grove analog connectors, as well as 1 Grove I2C connector, and 1 Grove UART connector. Program Code Firstly, the Seeeduino Nano is built around Atmega328P 8-bit AVR microcontroller. This is the same as the Arduino Nano board, meaning you can use the same program code on both boards. There’s no specific Wiki for Seeeduino Nano, but it’s similar, albeit much smaller than the well-documented Seeeduino V4.2. Price of the Seeeduino Nano Board The board is […]
