All the boards usually come with hardware support for digital communications protocols such as I2C, SPI, and UART. However, if you plan to use more of these interfaces than what is available on the board, you can use the programmable IOs provided in RP2040 microcontroller.
Well, this has more capabilities than one can think of. Let’s say you want to output a DPI video or “communicate with a serial device found on AliExpress” is now possible with Programmable I/O. As the name says, ‘Programmable’ IO makes it clear that it can be programmed directly to support several interfaces including SD card interface, VGA output, and higher speed data transfer. Hang on! We have the most exciting part of the article coming up – ‘How to program these programmable I/Os to make your job easy’.

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.
