Onion Omega is an Atheros AR9331 Wi-Fi Module Supporting Various Docks and Add-on Boards (Crowdfunding)

There are so many inexpensive Wi-Fi modules running Linux that it would be easy to discard Onion Omega as yet another Wi-Fi module based on Atheros AR9331 WiSoC. However, the developers have tried to bring some added value by making programming easier for web developers, integrating it with a cloud platform (free for non-commercial use), and providing basicor Arduino dock, and add-on boards for Ethernet, OLED, Relay… to make building hardware projects easier too. Let’s go through the hardware first, starting with the module specifications: SoC – Atheros AR9331 400MHZ MIPS 24K System Memory – 64MB DDR2 400MHz Storage – 16MB Flash Connectivity – 10/100 Mbps Ethernet + 802.11b/g/n Wi-Fi up to 150Mbps with PCB antenna w/ uFL connector I/Os – 18 GPIOs USB – 1x USB 2.0 Power Supply – 3.3V; Typ. consumption: 0.6W Dimensions – 28.2mm x 52mm (1.1″ x 2.0″) Since this type of module is not […]

$35 Tessel 2 IoT Board Features Atmel SAMD21 MCU and Mediatek MT7620n WiSoC

Tessel is a Wi-Fi IoT board based on NXP LPC1830 Cortex M3 MCU and Texas Instruments CC3000 modules, that’s designed to bring embedded development to web programmers with a system that can be programmed with JavaScript and Node.js. At the time of the crowdfunding campaign in 2013, the board was available with external modules (Relays, sensors, Bluetooth LE…) for $100 and up, but now Technical Machine, the company behind the project, has announced Tessel 2 combining Atmel SAMD21 Cortex M0+ to control I/O and Mediatek MT7260n for Wi-Fi connectivity, still programmable with JavaScript ot Node.js. Tessel 2 specifications: MCU – Atmel SAMD21G14A-MU Cortex M0+ MCU @ 48MHz with 16KB SRAM and 2KB Flash SoC – Mediatek MT7260n MIPS24KEc Wi-Fi SoC @ 580 MHz System Memory – 64MB DDR2 Storage – 32MB flash for firmware (OpenWRT) Connectivity – 10/100M Ethernet, and Wi-Fi 802.11 b/g/n with dual PCB antennas USB – 2x […]

DonglePi is a USB Dongle with a Raspberry Pi Header for your PC

While the newer Raspberry Pi A+, B+ and B2 boards feature the new 40-pin connector, the Raspberry Pi boards Model A and B have a 26-pin expansion header, but both are use to access GPIOs, UART, SPI, I2C and interface with external hardware, and many add-ons boards have been developed for the Raspberry Pi. But what if you’d like to use R-Pi add-ons board on your PC, or instead you are developing your own add-on board, but would like to do so directly on your PC for convenience? DonglePi is the answer. It’s a small USB dongle with Atmel SAMD21 MCU and a 26-pin Raspberry Pi compatible header, that you could use connect to your Android/Linux/Windows PC to play with GPIO, I2C, SPI, Serial, PWM just like on a Raspberry Pi, and using RPi/GPIO or smbus Python libraries for programming. The project is still in development, and so far most […]

HydraBus is an Open Source Hardware STM32 Devkit with Support for NFC via HydraNFC Shield

Recently, I wrote about the public availability of a MicroPython board based on STMicro STM32F4 Cortex M4 support that can easily be programmed with Python. It turns out there’s another STM32 board called HydraBus, also supporting Micro Python firmware, or another embedded firmware based on ChibiOS, together with an optional HydraNFC shield capable of sniffing, reading/writing or emulating any 13.56MHz NFC tags. HydraBus Specifications: MCU – STMicro TM32F405RG micro-controller @ 168 MHz with 1MB flash, 192KB SRAM, and an FPU.

WeIO is an Open Source Hardware IoT Board Programmable from a Web Browser (Crowdfunding)

WeIO is an open source hardware board for the Internet of things with Wi-Fi connectivity and lots of I/Os designed by nodesign, a French based startup, in collaboration of 8devices, the makers of the Carambola boards. WeIO is powered by an Atheros AR9331 SoC running OpenWRT as well as an NXP LPC MCU for faster handling of I/Os and support for analog I/Os. One interesting aspect of this board is that it can be programmed via a web browser using HTML5 or Python, and it does not rely on the Cloud to store data. WeIO hardware specifications: SoC – Atheros AR9331 MIPS 24K Wireless SoC @ 400 MHz MCU – NXP LPC11xx ARM Cortex M0 MCU for analog I/O and real-time H/W interfaces System Memory – 64 MB DDR2 Storage – 16 MB flash + micro SD slot Connectivity – 802.11 b/g/n Wi-Fi with on-board antenna (AP and STA modes), […]
