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.

We want to put our remote sense and control modules out into the wild and read and aggregate them as it makes sense.
Our basic system layout is as below. We’ve got multiple wireless nodes that broadcast data periodically, and a controller/aggregator that will log this data, acknowledge receipt, and do something useful with it. Eventually, we may have intermediate powered nodes that serve to mesh the grid out, but for now, our nodes just send data to the controller.
We’re currently using these awesome little RF units, called Moteinos. They are an Arduino clone that can use the standard IDE with their bootloader. They’ve got the ever-so-popular ATMega328P chip that is familiar to anybody working with an Arduino Nano or Uno.

I just got myself a couple of Arduino Due boards. While they were released almost two years ago, I have not really got a chance to look at these until quite recently. Arduino Due is based on Atmel’s ATSAM3x8E 32-bit ARM Cortext-M3 processor. The processor core runs at 84 MHz, which is significantly faster than its 8-bit AVR counterpart ATmega328p which runs at 16 MHz. For an ATmega328p, the highest achievable PWM frequency is 8Mhz (square wave), so we should be able to generate much higher frequency signals on an Arduino Due. But how high can we go? Let’s find out.

Here’s a DIY 38mm x 38mm laser engraver build using CD-ROM/writer on ATmega328p by Davide Gironi:
A laser engraving machine, is a tool that uses lasers to engrave an object.
To build this tool I’ve used two old CD-ROM writer that lays around in my garage.
The X/Y positioning system it is build using the CD-ROM motor assembly. For the engraving laser i use the CD-ROM writer laser.
With this hardware the engraving area are will be almost 38mm x 38mm.

“Plus” version of new graphic modules FTDI with an EVE technology brings a big plus in a form of a compatibility with an Arduino platform.
Innovative graphic chips of the family EVE were introduced to you in our article: Is a display design difficult? Leave it to „Eve“! or also in the webinar in cooperation with the producer – FTDI. This time company FTDI comes with another significant step to make development easier – compatibility with an Arduino platform.
New versions of VM800 modules with the „P“ (Plus) suffix contain besides the graphic chip FT800 and a touch display (3,5/4,3 a 5,0“) a RISC procesor ATMEGA328P (16 MHz) with a precompiled Arduino „bootloader“ (from the supplied 4GB uSD card). It means, that applications can be developed in a free Arduino IDE environment and to use a huge amount of Arduino libraries. “Plus” version also contains a USB interface with the FT232R chip and a precise bezel (Black or Pearl). Also available are over 50 sample “EVE” applications including various gauges, keyboards and other usable in a target device. It can be said, that the Plus series is designed to be directly used not only for development, but also into a target device as a standalone graphic module (HMI) able to control even other peripheries and to communicate through a USB port. The module can be powered through a microUSB connector or from an external 5V adapter.
FTDI brings for a maximum versatility two possibilities of programming:
• through a so called HAL interface (Hardware Abstraction Layer ) enabling cooperation with various MCUs through an SPI interface as described in the Application Note 246 – VM800CB_SampleApp_Arduino_Introduction
• by using Arduino libraries as described in the document Application Note 318 – Arduino_Library_For_FT800_Series
Be in plus with a graphic platform FTDI VM800P - [Link]
This week FTDI Chip have announced a range of Arduino-compatible development platforms to support the company’s Embedded Video Engine (EVE) technology. The VM800P series provides engineers with everything necessary to implement Human Machine Interfaces (HMIs) featuring display, audio, touch elements and data processing aspects too.
The units can be programmed using the standard Arduino IDE (using a pre-programmed Arduino-compatible bootloader). In addition to support for various Arduino libraries, every VM800P incorporates an FTDI Chip FT800 EVE graphic controller IC and its FT232R USB interface IC as well as an ATMega328P 8-bit microcontroller running at 16 MHz. Also featured are a touch-enabled display LCD panel, a backlight LED driver, an audio power amplifier and a micro speaker. A choice of 3.5, 4.3 and 5.0-inch display formats is available which have precision fitted bezels to enable operation in industrial environments. The VM800P units also have a USB serial port for firmware upload and application communication, a battery-backed real time clock (RTC) for carrying out system timing and a micro SD socket loaded with a 4GByte SD card containing sample applications.

This is pretty much one of those required projects; everyone builds a datalogger in an Altoids can. But each is different and I enjoyed making mine.
Uses ATmega328P (low power, 32K flash for lots of program space)
Uses Maxim/Dallas DS1337 Real Time Clock (uses I2C)
Logs data to microSD flash card, readable on PC (uses FAT32)
Runs on two AAA alkaline batteries
Low power draw (exact consumption varies based on SD card used)
Supports RS-232 for entering commands
Uses CR2032 lithium coin cell for RTC backup
Uses Analog Devices TMP36 for temperature sensor (not shown, it gets wired to the green four-position terminal shown below)
Uses SparkFun 3.3VDC boost converter to provide stable voltage even as batteries die

An incredibly small board at your fingertip: raising funds on Indiegogo!
A 100% Arduino IDE compatible, 32KB USB development board small enough to fit on your fingertips and cheap enough to leave in any project.
Having used several development boards over the years we soon realized that most of them are designed to be used for a single purpose. Having hacked some to increase functionality, we reasoned that not all boards would easily allow this and soon realized the need for boards which are feature rich, cost effective, yet easy to use and deploy in numerous applications. We set out to design such boards and this is where it has led us, our first pit-stop: The µ-nex.
The u-nex is a very compact Arduino compatible board designed around the Atmega328p micro-controller. It features 32KB of flash memory with ALL the micro-controller pins being brought out to enable you to build just about anything you would want to build with an 8-bit micro-controller from autonomous flying vehicles to LED cubes. Designed from the ground up to give you maximum possible versatility.

Frank Zhao shared his simple 6x USB charger with current monitor in the dangerousprototypes.com project log forum:
This is a simple 6 port USB device charger with a individual current monitor on each port. The charging current is indicated using RGB LEDs. Blue means slow charge (under 250mA), green means 250mA to 750mA, red means over 750mA, and purple means over 1500mA (for tablets). This circuit involves an ATmega328P (if you do hobby electronics, I bet you have plenty spares of these), INA169 (check out this breakout board), and a OKR-T10-W12.
