Wio GPS – also called Wio Tracker – is an Arduino compatible board based on Microchip Atmel SAMD21 MCU with GPS, Bluetooth, GSM/GPRS connectivity, as well as several Grove connectors to connect sensors and modules for your IoT project. SeeedStudio sent me a sample for evaluation, so I’ve tested it, and reported my experience below by testing some of the Arduino sketches. Wio Tracker Unboxing All I got in the package was Wio GPS tracker v1.1 board. The top includes the Atmel MCU, an RGB LED, a microphone and 3.5mm AUX jack to make phone calls, a user and power button, a micro USB port for power and programming, a small 2-pin connector for a battery, and 6 Grove connectors for digital, serial, I2C and analog modules. The other side of the board comes with Quectel MC20 module that handles Bluetooth, GPS and GSM, a dual use micro SD card […]
Apple Opens HomeKit Accessory Protocol Specification to Non-Commercial Projects
HomeKit is a software framework that allows Apple users to control smart devices with their iPhone or iPad. But so far, you had to become an MFI licensee to design a HomeKit compatible device, you product had to be tested by Apple, and – according to a story on Hackster.io – also required a special cryptographic chip for authentication. Developers creating commercial devices still need to become an MFI license, but Apple has now opened HomeKit Accessory Protocol Specification for non-commercial projects, meaning you can now use the Framework on Arduino, ESP8266 boards, Raspberry Pi, and other development boards using software authentication. You could already use HomeKit on Raspberry Pi board previously using HomeBridge, but the advantage now is that you don’t need to breach Apple’s terms and conditions, and you can talk directly to your phone without the need for a bridge. If you want the specifications got to […]
XOD is a Visual Programming Language for Arduino, Raspberry Pi, and other Maker Boards
When you think about visual programming on the Raspberry Pi or Arduino board, Scratch may come to mind, but some developers have decided to create their own visual programming language working for Arduino, Raspberry Pi, and other boards. Meet XOD, pronounced ksəud. The developers explains their used “functional reactive programming principles and added graphical functionality”. XOD is comprised of “nodes” that represents either some physical device like a sensor, motor, or relay, or some operation such as addition, comparison, or text concatenation, which you can link together through inputs and outputs to create a program, and XOD IDE will compile the resulting diagram to create and upload a binary program to Arduino, Raspberry Pi, etc… You can also convert a XOD diagram into a node with inputs and outputs to use it in another diagram, so the language is scalable. The developers are now looking for testers to play with […]
OpenH PULSAR and QUASAR Boards Add 4G LTE Cat M1, or Cat 4/1 to Raspberry Pi Boards
We’ve seen a bunch of IoT boards with 2G connectivity recently including Orange Pi 2G-IoT, Wio GPS, and Nadhat, but while in some countries 2G will still work for many years, those boards are already obsolete – or soon will be – in many other countries. However, finding low cost 3G / 4G boards is more difficult, and while one solution is to use 3G or 4G USB dongles, “OpenH – Open Hardware” – part of KLiP Industries – has designed two boards with 4G connectivity provided by Quectel modules. OpenH PULSAR Board PULSAR board is compatible with Arduino Zero and features the following specifications: MCU – Atmel/Microchip SAMD21 ARM Cortex M0+ MCU (the as the one used in Arduino Zero) Connectivity 4G LTE Cat M1 modem with GPS (Quectel BG96-NA); No external antennas required Bluetooth and NFC Security – Dedicated management CPU with crypto engine Power Supply 10W digital power supply and battery charger with direct solar input FCC […]
