Balloon 3 Breakout 2v2
This page contains the build info for version 2v2 of the Balloon Breakout board.
About 15 of these have been built.
It is possible, with skill, to build one by hand (Mantis and a good soldering iron are essential).
The bill of materials contains Farnell part numbers for the majority of parts that were fitted to the builds carried out so far. However these builds were limited to the programming functions on the board.
