Status of Orange Pi Boards GPIO Support

Yesterday, one person asked me to make a video showing GPIO control on Orange Pi 2 mini on YouTube, and since I have just completed a post about Orange Pi camera, I thought it might be fun to check GPIO support too. This post focuses on Allwinner H3 boards, but the instructions and status should be very similar for Allwinner A20 and A31s versions. One of the first things you want before starting playing with GPIOs is the expansion header’s pinout chart, and I could not find any until I had the idea to check for schematics, which are available on Orange Pi resources page. I downloaded the schematics for Orange Pi 2, which should be the same as for Orange Pi 2 mini as the only difference is the lack of WiFi module. Orange Pi PC is a little different, and the schematics are nowhere to be found, but […]

Gesto is a Wearable Gesture Motion Solution for Makers (Crowdfunding)

A while ago I wrote about an open source prosthetic arm controlled by signals generated by your arm’s muscles. It used an Arduino board, a bio-feedback shield by Olimex, and inMoov Hand for the arm and hand. It worked, but lacked accuracy. Gesto is a solution based on boards powered by Atmel MCUs that looks somewhat similar, but with higher accuracy (over 100 gestures have been tested), and the project has now been launched on Crowdsupply. Two kits are available: Gesto Stella EMG circuit – ADS1294 MCU – Atmel ATmega1284p 2x EMG cables connector Through holes with GND, PWR, MOSI, MISO, CLK and SC Dimensions – 35 x 20 mm Includes 16 disposable electrodes and relevant cables Gesto Caelum EMG circuit – ADS1294 MCU – Atmel ATmega1284p Sensors – 3-axis accelerometer (MMA8652FC) Connectivity – Bluetooth (RN42-HID) 2x EMG cables connector USB – Micro USB connector Programming – ICSP connector Power […]

Raspberry Pi Model B+ Price Drops to $25

When Raspberry Pi 2 was launched, Raspberry Pi Model B+ kept getting sold for $35 despite the lower specifications, but a week later resellers started selling Model B+ for as low as $30 shipped. But the Raspberry Pi foundation now announced an official new price for Raspberry Pi Model B+, which now sells for just $25 on RS Components and MCM Electronics with other resellers to soon follow. This makes R-Pi Model B+ relevant again for applications that do not require the extra horse power or memory brought by R-Pi 2 quad core processor and 1GB RAM.

Windows 10 IoT Preview for Raspberry Pi 2 and MinnowBoard Max

When Raspberry Pi 2 Model B was released, we were promised a Windows 10 image for the board, and today, Microsoft released “Windows 10 IoT Core Insider Preview” for both the Broadcom BCM2836 based Raspberry Pi 2 and Intel Atom E3800 series based Minnowboard MAX boards. To get started with either board, simply go to Windows IoT – Getting Started page. I’ll quickly go through the instructions for Raspberry Pi 2. Beside the board, you’ll also need a PC running Windows 10 Insider preview (Virtual machine not supported), a 5V power supply, a HDMI cable (optional but recommended), an Ethernet cable, and a 8GB micro SD card, class 10 or better. The you’ll need to configure a connect account, where I had to accept two EULA including “Windows 10 IoT Core Insider Preview EULA”, and once this is done the area of the page for EULA should just be blank, […]

$10 Digistump Oak ESP8266EX Board is Arduino Compatible, Connects to the Cloud, and More (Crowdfunding)

A few years ago, I wondered why adding Wi-Fi to Arduino had to be rather expensive ($40+), and why there weren’t any low cost and small form factor Wi-Fi boards for embedded applications. But we’re now in 2015, embedded is “dead” giving rise to IoT, and I’m left wondering how it’s possible to make IoT Wi-Fi modules that cheap, and whether people will ever stop churning out cheap Wi-Fi boards, as I’m flooded with such news weekly… So when I saw yet another ESP8266 board on Kickstarter I was about to dismiss it, but since it was made by Digistump, that has an active community with their other products like DigiSpark Pro or DigiX, I decided to have a closer look. Digistump Oak hardware specifications: MCU – Espressif ESP8266EX 32-bit microprocessor @ 80MHz (overclockable up to 160MHz) with 1MB ROM (~300KB available for user code), 64KB RAM, 512 bytes EEPROM […]

Tizen OS Ported to the Raspberry Pi 2

Tizen may not be overly used in devices, but there has been ports of the operating system on various ARM platform, mostly development boards, powered by Allwinner, Rockchip, Freescale SoCs, and more… Seeing the popularity of Raspberry Pi 2 Model B, Samsung Open Source Group decided to port Tizen to the latest version of the hobbyist board. The full instructions are rather long, and provided in the link above, but the main steps – using a Linux based computer – can be summarized as follows: Create a local copy of tizen-distro Add Raspberry Pi 2 BSP Meta repository Initialize the environment and modify some config files Start the build with Yocto: bitbake rpi-hwup-image. This should make a minimal headless? image Create an SD card image with tmp-glibc/deploy/images/raspberrypi2/rpi-hwup-image-raspberrypi2.rpi-sdimg using dd, an optional resize the parition with gparted or fdisk/resize2fs. Insert the SD card in to your Raspberry Pi 2, and have […]
