If you have to work with high speed devices or signals (USB, many high end ADCs, etc.) chances are you’ll need to deal with differential signals. Unlike single-ended signals, the layout requirements are quite different, and a lot more care needs to be taken when designing PCBs with differential traces. There’s LOTS of literature out there on the topic (thankfully), but working on a new board with differential signals this week I found Differential Signaling and it’s Design Requirements from Speeding Edge to be a good general purpose overview, with some concrete but accessible explanations, tip and tricks.
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.
