We’ve been designing all sorts of IR transmitters and receivers for the Adafruit shop lately, and a chance discussion got us thinking about IrDA – an old wireless protocol used in some PDAs, watches, laptops and toys. its not used anymore – bluetooth LE does a way better job – but there’s probably some cases where IrDA hacking could be useful such as communicating with retro devices or if you want an RF-less wireless link. here’s a board that combines a TFBS4711 transceiver (https://www.digikey.com/short/jn43cz31) with a MCP2112 codec (https://www.digikey.com/short/m8tp3708). you can communicate at 115.2kbps with RX and TX lines just like any UART. 115.2kbps is the standard baudrate. or, provide your own CLK for something like 9600 baud. Coming soon.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

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.
