This minimalistic board is packed with features and comes with an extensive ecosystem of documentation and firmware.
For the student (we are never too old) that wants to fast track his career as a professional firmware developer there is:
- a detailed getting started guide
- an Atmel AVR quick start guide, with tutorials and examples
- Recommend best practices
For the developer that wants to improve his game there is:
- A header to quickly connect different kinds of peripherals (GPIO, A/D, UART, SPI & I2C). Notice that each interface has it’s own +3V3 and GND pins to make wiring easier and also improves EMC.
- A full-featured CLI application to experiment with the connected device and verify that it works, before committing to a single line of C code.
- A firmware framework that lays the foundation so that you can quickly develop a new application.
- A Temp&Pressure Logger and Analog voltage Logger application that demonstrates how you can quickly develop your own custom logging application using the onboard AT45D DataFlash.

AtmelCorporation have announced two additions to their SAM G series of ARMCortex-M4-based MCUs. The two latest models are designated the SAM G54 and SAM G55. They feature high performance (up to 120MHz), low-power (102 µA/MHz in active mode, down to 5 µs wake-up) and tiny outline (as small as 2.84 x 2.84mm). Both are targeted at IoT applications and include all the features of the current SAM G family of devices including an Atmel | SMART ARM Cortex-M4 MCU + FPU (floating point unit) together with integrated sensor fusion algorithms.

Build a cheap and simple full software controlled step-up (boost) converter to drive a LED string of 10 LEDs. LEDs are used as string to light up a acrylic engraved plate placed in a holder (also made out 5 layers of lasered black acrylic glas). Step up is from 5V to about 30V, current regulated to about 20mA.

An app note from Atmel, digital sound recorder with AVR and DataFlash (PDF!):
This application note describes how to record, store and play back sound using any AVR microcontroller with A/D converter, the AT45DB161B DataFlash memory and a few extra components.
This application note shows in detail the usage of the A/D Converter for sound recording, the Serial Peripheral Interface – SPI – for accessing the external DataFlash memory and the Pulse Width Modulation – PWM – for playback. Typical applications that would require one or more of these blocks are temperature loggers, telephone answering machines, or digital voice recorders.

Although not officially released until December we were able to get a glimpse of Atmel corporation’s SmartConnect SAM W25 module at electronica 2014. This small module has been designed for use in IoT edge node applications. Edge nodes are parts of the IoT infrastructure where information interacts with physical events; these devices might, for example be inputting information from sensors or outputting control actions. The nodes also need to adapt the information to and from the network and provide data security.

Use a $4 microcontroller to launch web pages with the push of a button over serial I/O.. by Elliot Williams @ makezine.com:
A microcontroller is a self-contained, but very limited computer — halfway between a computer and a component.
The top reasons to integrate a microcontroller into your projects are connectivity and interactivity, and one easy way to get your microcontroller talking with the outside world is standard asynchronous serial I/O. Many devices can communicate this way, from wi-fi routers to GPS units to your desktop or laptop computer. Getting comfortable with serial I/O makes debugging your AVR programs much easier because the AVR can finally talk to you, opening up a huge opportunity for awesome.

Hey all, this is my first post on this blog, so I’d like to say hello! I’m Ian M, a high school student who likes breaking(/fixing(/breaking again)) electronic stuff. I was just sitting around, and I wanted to see how cheap I could make a usb avr isp programmer. I based the design off of http://www.simpleavr.com/avr/vusbtiny, which is based off of the original UsbTinyIsp. For the firmware, I just took their firmware and re-compiled it. The source is available at http://www.simpleavr.com/avr/vusbtiny/vusbtiny.tgz?attredirects=0. Their post uses 3 resistors, 2 diodes, 1 capacitor, and an MCU. I thought I could do better. Turns out you don’t need two of the resistors, or the diode. My schematics are released into the public domain, and the original code stays under its original licence (which I don’t exactly know what it is, but I bet it’s in the readme).

Baoshi of DigitalMe wrote an article detailing his minimalism ATTiny2313 development board build:
The AVR chip I’m talking about is Atmel ATTiny2313, in SOIC-20 package. To make the development board, I bought some 28 pin SOIC/SSOP to DIP adapters. These adaptors usually come in double sided design. Corresponding pins on both sides are connected via the plated through holes at edges.
I made a 2×3 AVR programming header by pulling off pins (longer ones) from a double-row right angle pin header and reinsert them into the plastic base. A needle nose pliers is very handy for this purpose.

Atmel have announced the introduction of the SAMA5D4 to their SAMA5 family of microcontrollers. These use an ARM Cortex A5 core and the new D4 adds H264, VP8 and MPEG4 720p video playback capability at 30fps.
According to Jacko Wilbrink, sr. director of MPUs at Atmel “With the large market acceptance of the Atmel SAMA5D3 Cortex®-A5-based MPUs, we are continuing to shape experiences surrounding the user interface for industrial and consumer applications. The SAMA5D4 enables the addition of video playback to control panels and displays at an unrivalled cost point, security and counterfeiting are becoming growing concerns within the rapidly growing IoT market. These applications require MPUs with advanced encryption while maintaining the same level of high performance. Atmel® | SMART™ SAMA5D4 is positioned to deliver the security and performance many Internet-connected systems require.”

A recent press release from Atmel has announced the introduction of the Arduino WiFi Shield 101 which can be connected to any modern Arduino R3 board to give connectivity to the Internet via any traditional Wi-Fi access points. This new Shield is said to offer secure, cost-effective, high-performance Wi-Fi connectivity. The new board is targeted at Arduino IoT applications and incorporates Atmel’s WINC 1500 wireless network controller offering IEEE 802.11 b/g/n (1×1) at up to 72 Mbps and supporting IEEE 802.11 WEP, WPA2 security enterprise.
