Introducing R2Duino: USB-stick sized Arduino with 2 relays

Post by arduino_fan » Sun Sep 19, 2010 4:25 am

The R2Duino is a fully assembled USB STICK sized Arduino clone based on the ATmega328. It has the same functionality as the Arduino Nano 3.0, but comes in a different package. It lacks only a DC power jack, but has a standard size USB connector which fits right into the USB connector of your PC. The name R2Duino comes from the fact that this microcontroller board has 2 RELAYS, connected to pins D8 and D9. The R2Duino was designed and is being produced by Certeza.

Microcontroller: Atmel ATmega328
Operating Voltage (logic level): 5 V
Digital I/O Pins: 14 (of which 6 provide PWM output)
Analog Input Pins: 8
DC Current per I/O Pin: 40 mA
Flash Memory: 32 KB (of which 2 KB used by bootloader)
Clock Speed: 16 MHz
Dimensions: 70 x 30 x 20mm
EXTRA: 2 relays (60V AC/DC 400mA) on pins D8 and D9, enabled/disabled by jumpers
EXTRA: Standard size USB connector

Included in the package:
4 rows of pin headers. You can solder them on the board if you need them.

R2Duino was especially designed for educational institutions.
