Everybody are making Arduino clones. So I thought I should make THE smallest. I took smallest package atmega88 – 28qfn (5mm x 5mm). Routed smallest possible resonator and as much pads as i could fit on in.

The result – Smallest Arduino clone ever! Size is only 7.4mm x 7.4mm! Features include:

  • Auto reset
  • UART
  • SPI
  • 4 analog channels
  • 1 digital i/o
  • one LED
  • funny readme with BOM

It needs arduino bootloader for atmega88 like ottantotto bootloader, probably it needs some hacking too because the resonator is 8MHz not the Arduino regular 16MHz.

Ben Eishen sent in this link. He says, “I have been thinking about building an ESR meter, and this one looks like a winner.” The design is based on the ATMega88 and according to the designer, Dr. Le Hung, “The LCFesR 4.0 unit is a precise, wide range meter that can measure inductivity, capacity, frequency and equivalent series resistance of a capacitor in-circuit, which can be easily built with homemade one- or double-faced PCB and available electronic components.” The video above shows the LCFesR measuring component values as compared to values determined by a commercial unit.

The schematic and documentation can be found on Dr. Le Hung’s website.

Jaanus has been working on a subminiature Arduino clone which be believes is THE smallest – [via]

Everybody are making Arduino clones. So I thought I should make THE smallest. I took smallest package atmega88 – qnf28 (5mm x 5mm). Routed smallest possible resonator and as much pads as i could fit on in.

His design provides SPI, UART, one LED and breaks out 4 analog and 1 digital IO pins.

USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an ATMega48 and ATMega88 an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed.

Features

  • Works under multiple platforms. Linux, Mac OS X and Windows are tested.
  • No special controllers or smd components are needed.
  • Programming speed is up to 5kBytes/sec.
  • SCK option to support targets with low clock speed (< 1,5MHz).

This project is a LED flower that uses PWM controlled RGB Leds which get their settings via USB using obdev.at’s USB stack. The controller board hosts an ATmega88 microcontroller which is running the V-USB stack so that it is controlled by a computer USB port. There is a total of 6 RGB Leds connected on the board using enamel wire.  You can find construction details, schematic and software on the link below. [via]

This project is a gear position indicator able to display the gear number for Suzuki V-Strom (DL650 and DL100) motorcycles. These motorcycles have the gear position sensor installed so it is possible to show gear number without any delay and with 100% accuracy. The sensor is read by an ATmega88 microcontroller and the gear is displayed on a 8×8 LED matrix. There is also a temperature and a light sensor installed so it can display the temperature reading and it is able to dim the LED light according to ambient light. Check details on the link below.  [via]

This little board is a header board for 28 pin ATmega microcontrollers. It’s great for prototyping on a solderless breadboard and supports ATmega48, ATmega88, ATmega168 and ATmega328. The best feature is that is Arduino compatible. You can build your own or buy a kit.

This is a simple signal generator which produces sine waves (or any waveform really) at audio frequencies using DDS and is controlled a USB serial connection.Only 2 chips are used in this circuit. The AVR ATmega88 which produces the signal, and an FT232R for the USB interface. While a computer is required to control the varying frequency of the oscillator, a fixed frequency project could be made without the USB interface. [via]

Before starting this Ethernet project the author did of course some prototyping and then he noticed alreadythat UDP was not a problem with lots of space left on the atmega88. Therefore he was quite confident that TCP + HTTP will work. TCP/IP was invented more than 25 years ago. Todays microcontrollers provide almost the computing power a standard computer had at that time. No java or xml was used at that time. Things were done in smart and efficient ways.

This is versatile development board for AVR microcontrollers ATmega48/88/168. It is good for testing and debugging embedded programs. It has many built-in peripheries connected to microcontroller so you can use them without soldering. ATmega microcontrollers are produced by ATMEL and they include a lot of features: I/O, Timers, PWM generators, ADC, RS232, TWI, SPI, Analog Comparator, Oscillator, EEPROM These microcontrollers are very versatile, easy to program and easy to use. This is the reason why I like these microcontrollers and why I decided to make development board for them.
