Etching PCBs is a topic I’ve covered quite a bit already, here and especially here. You might think I’ve beaten this copper and fiberglass horse to death. Well, I don’t want to be a one-trick pony, so there’s one more thing to try. Lucky for you, I’ve run out of horse-themed metaphors so I’ll just get to it.
I’ve been wanting to try two-layer PCB-making for a while now, because the boards I’m making for Veronica are reaching complexity levels where the top-side jumper count gets a little nuts. I also have lofty dreams of running boards above 10Mhz, and those jumpers will quickly become a liability. Furthermore, building jumpers is quite a bit of work, so if I can eliminate that, it would be a real win.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
