The first part of my HackadayU course on Embedded Serial Buses goes live in under a week! It's pay-what-you-want, all proceeds go to charity. Sign up here: https://www.eventbrite.com/e/hackaday-u-embedded-serial-buses-part-1-tickets-115774210781
If you sign up for the final week, you will automatically get the notifications for all four weeks. There is a live Q&A the day after each part goes live, which will be done (sadly) via Zoom.
