Yes, small is better!
And after our Slenduino, we present a project of Ritesh Kanjee, a developer that has created a small version of arduino Attiny85 based.
Ritesh propose this solution on indiegogo.com, it's would be both low power and inexpensive arduino, with a USB programming included into the bootloader and compatible with most of future button shields.
<<We wanted the answer to the fundamental question, "How many students know how to program a microcontroller or have a basic understanding of electronics?">> right question!
We had answered to it with our Slenduino, but we are pleased that we aren't "the only one"!
Just for specifications:
- Atmel ATTINY85-20H microcontroller
- USB Regulated Powered up to 800mA via external power supply or 500mA from PC/Laptop.
- Dimensions: 18.64 mm x 18.25 mm (0.73in x 0.718in)
- Programmable via USB or AVR mkII - Choice between USB bootloader .
- Arduino IDE 1.0+ (Windows/OSX/Linux)
- 6 x Available I/O Pins and I2C and SPI Expandable
- 8k Flash Memory without bootloader ( 6k after USB bootloader)
- I2C and SPI Expandable
- 3 x 8 bit Hardware PWM pins
- 4 x 10 bit ADC pins
- Power LED
- Test LED (Pin 1)
- Support for LabVIEW
- Soon to Be available in Deep RED (PCB Silkscreen)
Good project, you can find it on this indiegogo campaign page.
