May I humbly suggest you reach out to:
(These are twitter handles with the at-sign removed to satisfy this message board)
rwaldron (Rick Waldron, Johnny-Five developer)
reconbot (Francis Gulotta, node-serialport developer, primary JS library for talking to Arduinos and other robotics controllers)
voodootikigod (Chris Williams, ex-organizer for RobotsConf)
If I were you, I’d send all three of them a dev kit simply to get their feedback in this community and for the possibility they’d broaden your social media outreach.
