I don’t mind admitting, there have been a few times over the past month or so when I doubted we’d ever get here.

But! You all should now have tracking links, because your Spectrums are on their way. If you didn’t get a tracking link, please get in touch with Crowd Supply support.

What to Do When You Get Your ESP32 Rainbow

Everything should be installed and ready to go, the only thing you’ll be missing is games, so:

You can use the file browser to manage files and upload your own games as well. I recommend using the tap-to-z80 tool, as loading .z80 files is considerably quicker than .tzx or .tap files.

Tell Us What You Think (Good or Bad!)

Please send in a field report telling us how you’ve been using your ESP32 Rainbow. If your field report is selected, you’ll receive a $50 Crowd Supply credit, and your report will be published as an official project update, emailed to backers, included in the Crowd Supply newsletter, and featured on their social media. This could be your 15 minutes of fame!

You can also get in touch with us via the Crowd Supply page.

If you find any bugs, let’s track them on the GitHub firmware issue tracker, they’ll be much easier to triage and fix there.

Finally

I just want to say thank you to everyone who backed the project and ordered a board. You’re the ones who made this project a success.

Thank you!
