The Really Bare Bones Board (RBBB) is a mini board designed for those experimental applications that require small processors, such as wearable computing, near space experiments, toy prototyping, artist’s projects or any use for a fairly small, low-cost microcontroller.
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 (only the voltage regulator changes) and a bundle with a cable and a BUB II, which may be found here.

- 2.1mm power jack
- Optiboot bootloader (Uno setting)
- 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)
- Unassembled kit
- PCB only (No parts, no headers)
- If you’re looking for an RBBB with the parts already soldered on, you should buy the RBBB Pro instead.
