I’ve spent the last several days building and programming the “bed-of-nails” test fixture that we’ll be using to test every Teensy 3.0 board. The hardware was designed many weeks ago, but the PCBs only recently arrived.
…
The pins are part numbers S-100-K-3.5-G and S-50C-TL-3.2-DG-S. Both can be purchased from Mouser Electronics. The 2 boards were ordered from Laen’s OSH Park http://www.oshpark.com/ Laen’s PCBs work particularly well, because they’re from a USA-based manufacturer with much higher accuracy drilling than other low cost services. For placing the test pins, this matters greatly.
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.
