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!
