Will Hart from the team at Particle wrote up some insightful – and helpful – pointers for anyone embarking on prototyping their first PCB with a trajectory towards larger manufacturing runs. He goes over everything from multiple reflow options to solder paste temperature to recommending conditions for assembly and inspection. It’s an extensive read – over 3,000 words – but worth it for anyone thinking of scaling up their project beyond a few through-hole perfboard prototypes.
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.
