For the annual i&i-conference, I try to find a ‘new’ gadget for speakers and board members. Last year we bought Inky Phats with a Raspberry Pi Zero W. To be used as interactive name badges. A great success! In this article, I’ll share 5 tips on how to use the display and I’ll be discussing a few problems. Inky pHat is an epaper display with a dedicated controller in the pcb. Plug and play!
