Ultra-narrow DipDuino Arduino Compatible Board is a Perfect Breadboard Companion

Ultra-narrow Arduino Board for Breadboard

We previously wrote about a uChip DIP-sized Arduino Zero compatible board with 0.3″ spacing between the two rows of pins making it perfect for breadboards as it left four rows on each side of the breadboard. There’s now another similar option with the appropriately named DipDuino board equipped with a Microchip Atmega328P MCU compatible with Arduino  Pro or Pro Mini boards. DipDuino specifications: MCU – Microchip Atmega328P 8-bit AVR MCU with 32KB flash, 1024 Bytes EEPROM, 2KB SRAM USB – 1x Micro USB port for power and programming via CP2104 USB to serial chip Expansion Two rows of headers spaced by 0.3-inch (7.62mm) with up to 21x GPIOs, 5x analog inputs, I2C, SPI, UART, Reset, VCC and GND I/O voltage – 3.3V or 5V (different versions of the board) Misc – RGB LED for power and UART Tx/Rx; reset button Power Supply – 5V via Micro USB port; LDO for 3.3V version Dimensions – 46.26 x 9.3 mm DipDuino comes …

Grove Beginner Kit for Arduino Features Arduino UNO Compatible Board & Ten Pre-wired Modules

Grove Beginner Kit for Arduino

Arduino boards are great to get started with electronics has they offer an ecosystem of expansion modules and libraries, as well as tutorials, that may it easy to get started with almost any projects. Seeed Studio Grove is a family of standardized modules with 4-pin headers using digital I/O, analog I/O, UART or I2C interfaces and allowing you to easily connect to compatible board such as Seeeduino Lotus board. You still need to connect the Grove module via cables, so Seeed Studio decided to create a big board called Grove Beginner Kit for Arduino that features Seeduino Lotus at the center and ten pre-wired and detachable Grove modules so no cabling is required to get started apart from a USB cable. List of Grove Beginner Kit for Arduino board and modules: Seeeduino Lotus ATmega320p board compatible with Arduino UNO compatible board and featuring 12 Grove connectors 10 pre-wired modules without the requirements for breadboard nor jumper cables Grove LED Grove …

Know the Differences between Raspberry Pi, Arduino, and ESP8266/ESP32

Raspberry Pi vs Arduino vs ESP8266 / ESP32

CNXSoft: This is a guest post written in collaboration with SurfShark. When it comes to choosing a platform for STEM education or hobbyist projects, there are a number of low-cost, compact maker boards on the market. The most popular include the kid-friendly Raspberry Pi SBC that was designed with children in mind, Arduino boards for electronics projects, and more recently boards and modules based on EspressifESP8266 and ESP32 wireless SoC’s. In this post, we’ll look at the use cases and strong points for each of the boards whether you are just dabbling in the hobby of coding and DIY electronics, or you have a commercial project. Raspberry Pi The Raspberry Pi is a lineup of single-board computers (SBCs) that are from the UK and were first introduced in February 2012. These small computers were initially designed to teach students the basics of computer science, but they’ve found their way into various projects including commercial products. To the uninitiated, the Raspberry …

An Arduino based Open Source Ventilator to Fight against COVID-19?

Arduino Open Source Ventilator

COVID-19 has disrupted most people lives well beyond the health crisis, with an economic fallout on-going that may lead to a 24% GDP contraction in the US and up to 12% worldwide in Q2 2020, and I assume the consequences may span over several years, so we should do everything to mitigate any effects from the disease. Right now, the urgent part is to handle the health crisis, and there’s a shortage – or soon will be – of medical supplies such as ventilators for people in critical conditions, and if hospitals become full they’ll start refusing admissions of some people even in critical conditions, as it happened in Wuhan, letting people die at home. So there are various initiatives and projects to develop open-source ventilators. First, Innovation Management reports Ennomotive has launched a non-profit online competition for the ideation of low-cost, easy-to-build solutions with the goal of speeding up the availability of ventilators in hospitals everywhere to help patients …

GetWired Aims to Make RS-485 Wired Home Automation Affordable and User-friendly (Crowdfunding)


You may think about installing a home automation system, and WiFi may appear like the obvious way to go since it removes the need for cumbersome cabling, but wired networks are more reliable and secure, and there’s no need for batteries to be recharged or replaced. However, such wired home automation systems may be difficult to install and are often expensive, so Domatic decided to work on a solution to lower the costs and improve the ease of installation and use. Meet GetWired RS-485 wired home automation solution. Getwired is comprised of four modules communicating over the standard RS-485 protocol: MCU Module based on Microchip ATMEGA328PB MCU @ 8 MHz with 64KB SPI flash, an RS-485 transceiver, a 12-pin interface for connecting shields and 6 different Molex connectors for I/O including PWM, analog, interrupt pins, as well as I²C and 1-wire interfaces – Dimensions: 40 x 25 mm 2SSR Shield – 2-channel AC controller shield with solid-state relays, supporting 200 …

Linux 5.5 Release – Main Changes, Arm, MIPS and RISC-V Architectures

Linux 5.5 Changelog

Linux 5.5 has just been released by Linus Torvalds: So this last week was pretty quiet, and while we had a late network update with some (mainly iwl wireless) network driver and netfilter module loading fixes, David didn’t think that warranted another -rc. And outside of that, it’s really been very quiet indeed – there’s a panfrost driver update too, but again it didn’t really seem to make sense to delay the final release by another week. Outside of those, it’s all really tiny, even if some of those tiny changes touched some core files. So despite the slight worry that the holidays might have affected the schedule, 5.5 ended up with the regular rc cadence and is out now. That means that the merge window for 5.6 will open tomorrow, and I already have a couple of pull requests pending. The timing for this next merge window isn’t optimal for me – I have some travel and other things …

Piksey Atto is a Tiny Arduino Compatible Board with Castellated Holes (Crowdfunding)

Piskey Atto

Atto is a unit prefix in the metric system denoting a factor of 10−18, so it’s unsurprising that at least one company, namely Nionics, made a small Arduino compatible board called Atto. But somebody must have forgotten to do a web search, as BitsNBlobs Electronics created their own tiny Arduino compatible board, also named “(Piksey) Atto“, and based on the same Microchip ATmega32U4 8-bit AVR MCU. But there are some important differences as we’ll see below. Piksey Atto specifications: MCU – Microchip ATmega32U4 8-bit AVR microcontroller @ 16 MHz with 32KB flash, 2.5KB SRAM, 1KB EEPROM Expansion – 18x castellated through holes for 11 digital I/Os, 4x PWM, and 4x analog inputs, USART/SPI/I2C USB – Micro USB port for power and programming Power Supply – 5V via micro USB port Dimensions – 20.32 x 12.7mm Weight – 1.3 grams Piksey Atto is about twice the size and weight of Nionics Atto, lacks LEDs, and a reset button, but offers breadboard …
