I am about to place a manufacturing order for a batch of the latest Balloon 3 programming boards for TCL and iEndian.
This is likely to be the last batch produced. The next version will be based on Bubble.
Details can be found here.
I'm happy to add further boards for anyone else, these will be £130 (+VAT) each + postage at cost.
The latest version has Pinko Compatibility with most earlier revisions of Balloon3 and the build will be a Full Fit as detailed in the above documentation.
Should you prefer to make your own all the manufacturing data and part data is available at the link above.
