This is a small board with a lot of digits. Featuring four HP 4-digit 7-segment bubble displays on a board designed to be mated with the Adafruit HT16K33 breakout, this will quickly allow you to display four values using i²c. Source Files can be found on GitHub.

Note, the board to board connector on this version does not support normal header strip (the holes are too small) either use wire or appropriately sized machine pin connectors such as these.

Mounting:

• Solder a right angle header strip to the bottom header for vertical mounting.
• Solder straight header strips to the bottom or both headers for horizontal mounting.
• The top header is not electrically connected and is for more stable horizontal mounting.
