(Video) 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!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
