The Great Search – 3V TTL to RS-232 converter #DigiKey #adafruit @digikey @Adafruit
(Video) To get a nifty Spaceball user interface working, we’re using a USB to RS-232 adapter cable. But for the next step in this project, we’ll want to use a Feather board.
In order to connect to the DE-9 port safely, we need to convert the TTL serial on a Feather (0-3V logic) to +-6~10V inverted logic. Thankfully, there are chips that make it easy – they even have built in switched-cap converters to create the +6V and -6V logic rails! Let’s find one that we can use to make an adapter FeatherWing with.

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.
