Raspberry Pi Zero (W) Shield for Arduino is an Arduino UNO Baseboard for RPI Zero Board

There are already various Arduino compatible shields for Raspberry Pi  where the add-on board connect to a Raspberry Pi 3 board to provide  Arduino headers, but Raspberry Pi Zero (W) Shield for Arduino is a little different as it acts as a baseboard with Arduino header for Raspberry Pi Zero (W) RPI Zero (W) shield specifications: Reset switch for the micro-controller LED – Shield power LED,  LED connected to Arduino pin 13,  LED connected to Raspberry Pi GPIO pin 13 Expansion Female headers allowing for full-access to all Arduino pins. ICSP header access for AVR Micro-controllers Misc 3mm mounting holes for securely mounting Raspberry Pi Zero (W) to shield (mounting hardware included) Solder-jumpers to disconnect Micro-controller SDA/SCL pins from pull-up resistors Solder-jumper to disconnect Raspberry Pi GPIO13 from LED Power Supply – 6.5 to 12V power supply (6.5 to 9V recommended) via  2.1mm power barrel jack, or 5V via micro […]

NoCAN IoT Platform Leverages Raspberry Pi & Arduino for CAN Bus Projects (Crowdfunding)

Many IoT projects rely on wireless connectivity through WiFi or Bluetooth, but in some cases it may be more reliable and convenient to use wired connectivity. The CAN Bus is a little like a low bandwidth Ethernet PoE solution for IoT, as it allows to transfer data over a serial connection while provided power at the same time, and can be daisy chain to support multiple boards. Omzlo’s NoCAN IoT platform provides a CAN bus solution leveraging Raspberry Pi 3 board through their PiMaster HAT acting as a CAN bus gateway, and Arduino compatible CANZERO boards to which you can connect sensors and actuators. Omzlo PiMaster HAT specifications: MCU – STMicro STM32F042 Cortex-M0 32bit ARM MCU – 48Mhz. Networking –  125000 bps CAN bus up to 300 meters range GPIO – Communicates with Raspberry Pi through SPI + GPIOs Security – Smart power switch with over-current protection. Power Supply – […]

RasPad is a Tablet Kit for Raspberry Pi 3 B+ and Other Development Boards (Crowdfunding)

Many people interesting in coding and working on projects with the Raspberry Pi  just likely connect the board to a monitor, USB keyboard and mouse, and to a power adapter, but if you are interested in having some more compact and portable RasPad tablet kit may be for you. The kit is compatible with Raspberry Pi boards, including the latest Raspberry Pi 3 B+, as well as other Arm/x86 Linux development boards including Tinker Board, LattePanda or BeagleBone Black. [Update: The design likely only works with RPi form factor, so if you use other boards with HDMI output, you may have to leave them out of the housing] RasPad key features: Display – 10.1″ IPS touch screen Video – HDMI port Audio – 2W speaker, audio jack Misc – 3 buttons (volume/brightness +, volume/brightness -, power), micro “USB touch” port Battery – Good for about 3 hours Power Supply – […]

Shedbuilt Binary Blob-Free Linux Distribution Works with Allwinner H3/H5 Boards (Orange Pi, Libre Computer)

Most open source Linux distributions are only partially open source, as while most packages will be built from publicly available source code, they usually come with closed source binary blobs for GPU drivers,  wireless module firmware and so on. Shedbuilt is described as “a decentralized, self-hosting GNU/Linux for Arm devices built from the latest upstream sources”, and as the developer (Auston Stewart) explains – see comments section –  it does not contain any binary blob. Eventually the distribution may support more boards, but for now, the current System 1 “Amano” release supports four Allwinner H3/H5 boards: Orange Pi PC, Orange Pi One, Orange Pi PC 2, and Libre Computer ALL-H3-CC “Tritium”. Orange Pi Lite (with WiFi) and Libre Computer AML-S905X-CC “Le Potato” images are said to be coming soon. You can download the SD card images and access documentation on Shedbuilt.net. The Linux distribution relies on Shedmake script to automate […]

Getting Started with TinyLIDAR Time-of-Flight Sensor on Arduino and Raspberry Pi

TinyLIDAR is an inexpensive and compact board based on STMicro VL53L0X Time-of-Flight (ToF) ranging sensor that allows you to measure distance up to 2 meters using infrared signals, and with up to 60 Hz. Contrary to most other VL53L0X boards, it also includes an STM32L0 micro-controller that takes care of most of the processing, frees up resource on your host board (e.g. Arduino UNO), and should be easier to control thanks to I2C commands. The project was successfully funded on Indiegogo by close to 600 backers, and the company contacted me to provided a sample of the board, which I have now received, and tested with Arduino (Leonardo), and Raspberry Pi (2). TinyLIDAR Unboxing I was expecting a single board, but instead I received a bubble envelop with five small zipped packages. Opening them up  revealed three TinyLIDAR boards, the corresponding Grove to jumper cables, and a bracket PCB for […]

Pulurobot is a Low Cost Open Source Raspberry Pi based Load Carrying Autonomous Robot

Earlier today I wrote about FOSDEM 2018 schedule, and among the various talks I selected for my virtual schedule was “How to build an autonomous robot for less than 2K€”.  Some excerpt from the abstract including a short description of the project, and its “open-sourceness”: PULUrobot solves the autonomous mobile robotics complexity issue without expensive parts, without compromise. By fearless integration and from-scratch design, our platform can do SLAM, avoid obstacles, feed itself, and carry payload over 100kg, for less than 2,000 EUR. Application ecosystem can be born around it, as we offer a ready-made Open Source (GPLv2) solution in a tightly coupled HW-SW codesign. So I decided to have a closer at this project, which can be used as a robot maid/helper of sort, and other applications. The robot was made by a brand new (July 2017) startup called Pulu Robotics Oy and based in Finland. They have three […]
