Two odd circuit boardsThis is my first try to get circuit baords in unusual shapes - I drew the edge cut layout in a regular CAD program and then imported it into KiCAD. The team at pcbgogo had no problem to deliver exactly what I had expected and designed. This pcb is the display board for a model of a famous street clock in Berlin. The 24 LEDs are controlled using Charlieplexing over just 6 lectrical connections to an external microcontroller. Watch me assembling and testing the first board: https://youtu.be/h2aJxNj8B6A611 0 Apr 18.2022, 22:33:12 -
ATmega32U4 breakout board - assembledEven though this board has much less components than my previous designs I decided to test PCBgogo's assembly service. And I must say that the result is of the same high level of quality as their PCBs. Very clean soldering, accurate placement, quality components. I will most probably come back with a more substantial order of this design.2287 0 Jul 28.2020, 01:15:57 -
ATmega32U4 breakout boardI desigend this board primarily for the use with my students as a replacement for the combination of an ATmega328 and a separate programmer. Using a slightly modified Caterina bootloader it can be used as an Arduino or as an AVR microcontroller without the Arduino framework. More documentation to follow. THe pictures show the rendering from KiCAD and the delivered PCB.1836 0 Jul 28.2020, 01:09:57 -
