It’s a mega-mailbag day today, as we investigate two new dev kits we got this week: one is the Next Mind EEG/brain-sensor development platform with Unity SDK. The other is the HiFive+BBC Inventor Kit which uses Tynker for Micropython & block-based programming to program a ‘hand-y’ RISC-V board.We also have some really pretty E-Ink sample displays we added support for, and a silk scroll gift.

In this Great Search we’ll look at Crystals, Oscillators and even touch on Resonators. Which one do you need, and when can you use em? All that and more, with our hard-earned lessons on picking out the clock-generator you need https://www.digikey.com/short/z1233w
