$5 Add-on Board for Raspberry Pi Supports Arduino Shields and Grove Modules (with Caveats)

If you have several Arduino shields, you can use them on your Raspberry Pi B+/ Pi 2 board with Cooking Hacks’ Raspberry Pi to Arduino shields connection bridge supported by arduPi library to control I2C, SPI, GPIO, analog inputs, etc.., and sells for $65 on Amazon. Seeed Studio Grove modules have also become more popular, with several new boards integrating 4-pin Grove connectors such as Beaglebone Green. Raspberry Pi boards also support Grove modules, up to 15 of these!, using Grove Pi+ add-on board which the company sells for around $30. But I’ve just discovered a Raspberry Pi to Arduino Expansion Board V2.0 on DealExtreme, selling for $7.97 that’s allows the latest Raspberry Pi boards with a 40-pin headers to take both Arduino shields and 2 Grove modules. After some investigations, I found out it was made by ITead Studio, where they sell it for $5 + shipping. The Wiki […]

How to Use Nextion Serial Touchscreen Displays – Part 1: Standalone Mode

Itead Studio launched an Indiegogo campaign earlier this year for their Nextion TFT displays that can be connected to external board such as Arduino or Raspberry Pi via the serial interface, or even a standard computer provided you have a USB to TTL debug board. The campaign was successful with over 1,700 backers, and the company recently sent me two samples for review: a 2.4″ display and a 5″ display. In this post, I’ll look at the boards, and make a small standalone demo with Nextion Editor in Windows. Nextion NX3224T024 2.4″ Display The first item is a 2.4″ TFT display called NX3224T024_011N (non-touch) or NX3224T024_011R (Resistive touch) with 65536 color, 320×240 pixel resolution, LED backlight and up to 200nit brightness. It ships with a cable for the serial connection (5V, Tx, Rx, and GND). The back of the display features the serial connector, a micro SD used to load the […]

Razberry Board and UZB Dongle Add Z-Wave (Plus) to Raspberry Pi Boards

Z-Wave is one of the low power wireless communication protocols used for automation, and supported, for example, by gateways such as Samsung SmartThings Hub or Vera3. Z-Wave Plus is a certification program used to identify Z-wave 5th Generation hardware platform, allowing a greater range up to 45 meters, 50% improvement in battery life, 250% more bandwidth, and providing a standardized method for Over the Air firmware updates (OTA), among other things. Zwave.me, a startup registered in Switzerland, is specializing in Z-Wave products and solutions, and among their other products they’ve also designed Z-Wave hardware to turn the Raspberry Pi board and other compatible hardware into a Z-Wave gateway. RazBerry module will fit into the 26 or 40-pin header found on Raspberry Pi boards, and comes with the following specifications: Sigma Designs ZM5202 Z-Wave transceiver module Frequencies – Storage – 32KB SPI flash for network data CPU/MCU Interface – UART (Tx/Rx) […]

Element14 and Raspberry Pi Trading Launch a Raspberry Pi Customization Service

While the Raspberry Pi Foundation is the main face of the Raspberry Pi board, it only mainly promotes children’s education, and a subsidiary called Raspberry Pi Trading, funded in 2013, handles design, manufacturing and distribution of the Raspberry Pi boards, and puts profits back into the charity. Raspberry Pi Trading has now partnered with Element14 to offer customization services for the Raspberry Pi board. That means you’ll be able to remove or add interfaces and headers, replace the micro SD by a more reliable eMMC flash, add new functionalities to the board, and even re-design the layout in order to better match your project’s requirements. The companies “expect order quantities to start in the region of between 3,000 and 5,000 depending upon the nature of the customization”, so the service does not seem to be available , or cost effective, for smaller orders for a few hundred units. Element14 has […]

UP Board is a Raspberry Pi Clone with an Intel Atom X5 Processor (Crowdfunding)

Many ARM based “insert-fruit-name-here” Pi boards are available on the market, and they all look like the Raspberry Pi board to some extends, but thanks Emutex we’ll soon get the “UP board” powered by Intel Atom x5-Z8300 and in Raspberry Pi form factor including the ubiquitous 40-pin Raspberry Pi headers, DSI and CSI connectors, and mostly the same port placements, with some extra goodies like a USB 3.0 port and Gigabit Ethernet. Up Board specifications: SoC – Intel Atom x5-Z8300 “Cherry Trail” quad core processor @ 1.44 GHz (Burst frequency: 1.84 GHz) with Intel Gen8 HD graphics @ 500 MHz System Memory – 1 GB DDR3L-1600 Storage – 16 or 32 GB eMMC Video Output / Display – HDMI, DSI connector Audio I/O – HDMI Connectivity – Gigabit Ethernet USB – 4x USB 2.0 host ports, 1x USB 2.0 pin header, 1x micro USB 3.0 port (under the board) Camera […]

ZeroPi is an Arduino & Raspberry Pi Compatible Motor Control Board (Crowdfunding)

Pi boards keep on coming… As soon as I finished writing about Roseapple Pi board, yet another one popped out on my twitter feed… But that one is of a different kind, as it won’t run Linux, but instead the board is powered by an Atmel SAMD21 Cortex M0+ micro-controller, and can support lots of electric motors including up to 11 micro servos and 8 DC motors – or 4 stepper motors – simultaneously. ZeroPi board specifications: MCU – Atmel SAMD21J18 ARM Cortex M0+ @ 48 MHz with 32 SRAM and 256KB flash I/O pins via 33-pin header, 4-pin temperature sensor, and 10-pin Raspberry Pi header 35 GPIOs 4x 12-bit ADC channels 1x 10-bit DAC 2x UART 2-channel temperature sensor interface DC current per I/O pin- 7mA DC / Stepper Motor control – 4x 4-channel SLOT interface compatible with common parts such as DRV8825 or A4988 Stepper motor driver and […]

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 […]
