This week we're continuing on last week's RS-232 FeatherWing and looking at maybe making a multi-use design. We've also had requests for an RS-485 FeatherWing and perhaps we can design something that could be used for either. We've used a 'MAX232'-like before, but for RS-485 we'll need a different kind of chip, one that does a differential transmission. Let's see what's available and how we would wire it up!See on Digi-Key here! https://www.digikey.com/short/pd3945wwSee other episodes of The Desk of Ladyada in the playlist here https://www.youtube.com/playlist?list=PLjF7R1fz_OOXUtaFu7-_D1UCugC8OecKvand other Great Searches in the playlist here.https://www.youtube.com/playlist?list=PLjF7R1fz_OOVHqJN28IbXLBj1FKCxw-xDVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/
