It’s one of the smallest and lowest-cost Arduino-compatible boards available right now. You can build a RBBB in under half an hour, even as a beginner. The pin labels on version B2 are now between the pins, similar to the Arduino Nano.

We recently added 3.3V models and a bundle with a cable, and a  BUB II. When ordering the bundle you may specify cable length (1', 3', 6') and voltage (3.3V or 5V) on the cart page or we will  supply a 3' cable and a 5V regulator as the stock option.

Also available in Europe at JeeLabs.org.

Specifications

• 2.1mm power jack
• Arduino Diecimila bootloader
• ATmega328 Chip
• L4931CZ50-AP TO-92 low dropout regulator (300 mA)
• Note: Regulators such as MC7805CT-BP , LM2940 , or other TO-220 1A regulators make great alternatives if you need more power on your breadboard.
• We now also have these available with 3.3v regulators (L493133)
