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 …

Seeeduino Crypto Board Combines Microchip ATmega4809 MCU and ECC608 Crypto Chip

Seeeduino Crypto

With the advance of IoT, security has become critical since devices are often connected to the Internet. There are several ways to improve security and one of them is to implement hardware security via crypto chips. One of those chips is Microchip ECC608 (aka ATECC608A) secure element which we previously found in Linux based hardware such as USB Armory MK-II USB Linux computer, and the official Arduino Nano 33 IoT Board. Seeed Studio has now introduced a new Arduino compatible board with Microchip ECC608 crypto chip: Seeeduino Crypto board powered by a Microchip ATmega4809 8-bit AVR MCU. Seeeduino Crypto specifications: MCU – Microchip ATMEGA4809-AFR 8-bit AVR microcontroller @ 16 MHz with 48KB flash, 6,144 Bytes RAM USB – 1x USB Type-C port Expansion Arduino Uno headers with 6x analog inputs, 14x digital I/O pins, 5x PWM 2x I2C Grove headers 1x UART Grove header HW Security – Microchip ECC608 secure element with Protected storage for up to 16 Keys, certificates …

Marlin 2.0 Open Source 3D Printer Firmware Finally Released

Marlin 2.0 Firmware Release

Back in June, we wrote about Marlin 2.0 firmware supporting ESP32 3D printer board, but at the time the firmware was still in RC1 (Release Candidate) phase. I was informed Marlin 2.0 firmware had been in beta for several years now, but the good news is that Marlin 2.0.0 open-source 3D printer firmware has now been officially released. Some of Marlin 2.0.0 new features include: 32-bit support with several boards including Arduino DUE (SAM3X8E), Adafruit Grand Central (SAM5D), Smoothie / SBASE / EZBoard based on NXP LPC176x, SKR Mini powered by STM32, as well as ESP32 boards Some improvements were made to some AVR boards including Melzi (ATmega 1280), RAMPS (ATmega 2560), and RAMBo / miniRAMBo / Einsy RAMBo boards PlatformIO build environments for supported boards VSCode “Auto Build Marlin” extension for one-click build Power-Loss Recovery for SD print jobs Magnetic Parking Extruder support Magnetic Switching Toolhead and Toolchanger support Gradient Mixing and Gradient Virtual Tools Automatic power supply control …

YABA is a Backplane Architecture Controller for Automation and IIoT (Crowdfunding)

Automation and IIoT Through YABA YABA is an acronym and a concept being developed. The acronym is Yet Another Backplane Architecture (YABA). The concept is to bridge the gap between PLC/PAC and open source hardware. The YABA Bridge to IoT YABA is designed to be a robust, open hardware controller that will be a simple but effective midpoint or bridge to the approach of modern industrial technologies in the automation and IoT sector, especially production lines in industrial settings. Where YABA is in Process The process is midstage right now, with a prototype coming. There is an IndieGoGo campaign, but it is at the development stage right at this moment. The developer has reported that the team is about two months out of a working prototype, which should put them an efficient schedule timeline. The project has the backplane, CPU, I/O boards at about 75% complete, and just working towards the sleek enclosure which is what needs funding. The Ongoing …

UnaMKR Sigfox Monarch Development Kit Follows Arduino MKR Form Factor

unamkr sigfox monarch

Unabiz is an IoT network operator with offices in Singapore and Taiwan. The company offers Sigfox networks in the region, and last year unveiled UnaMKR, a Sigfox Monarch development kit compatible with the tiny Arduino MKR boards. We’ve already written about Sigfox LPWAN standard several times, but what is Sigfox Monarch exactly? Answer direct from Sigfox website: The Monarch feature makes IoT devices aware of the local radio configuration (RC) to use. A single device can thus lawfully communicate on the Sigfox network even when moving between countries with different radio regulations. That means a Sigfox Monarch compliant end-point can work legally anywhere in the world switching to 868 MHz, 902 MHz, and 920 MHz frequencies automatically depending on the country of operation. This is useful for asset tracking across countries and continents. Back to the board itself, with UnaMKR specifications: Platform – Arduino or STMicro Connectivity Lite-On WSG309S Sigfox Monarch + Bluetooth 5.0 LE Module Antennas – Sigfox: ½ …

$6.90 Seeeduino Nano Board | Compatible With Arduino Nano

Seeeduino Nano board

Seeed Studio has announced the release of yet another compact  board. The new board, Seeeduino Nano, is quite similar to the Arduino Nano board, and fully compatible. Another thing about the new board is that it has some different features. Seeeduino Nano comes with only one on-board Grove connector, but it can be expanded with the optional Grove shield adding 8 Grove connectors. More precisely, the shield has 3 Grove digital connectors and 3 Grove analog connectors, as well as 1 Grove I2C connector, and 1 Grove UART connector.   Program Code Firstly, the Seeeduino Nano is built around Atmega328P 8-bit AVR microcontroller. This is the same as the Arduino Nano board, meaning you can use the same program code on both boards. There’s no specific Wiki for Seeeduino Nano, but it’s similar, albeit much smaller than the well-documented Seeeduino V4.2. Price of the Seeeduino Nano Board The board is available for just $6.90 and the Grove shield for the …
