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 low-cost microcontroller.
As far as we know, it’s the smallest and lowest-cost thru-hole Arduino-compatible available right now. You can build a RBBB in 45 minutes, even as a beginner. The pin labels on version B2 are now between the pins, similar to the Arduino Nano.
Remember that, like the Aurduino, this version uses 5v for chip supply and logic levels. There are 3.3V versions of this board available also - please contact order_assistance @ jee labs.org if you think you need a 3.3V version.
You'll also need a USB-to-serial connection device, such as the USB BUB, to provide a connection path for uploading sketches.
Try the RBBB Combo Pack if you do not have an upload device - it also includes the correct USB cable.
- 2.1mm power jack
- OptiBoot 4.4 bootloader (Uno board compatibility)
