About the Diyosc PCB
Diyosc is an open source PCB design by agkaminski, published on GitHub. It is a 2-layer board measuring 12.7 × 20.3 mm, with 7 components from 5 distinct parts.
Other key parts include the 74HC00. By type, the board carries 3 resistors, 2 capacitors, 1 IC and 1 crystal.
From the project
Various hardware projects that do not deserve their own repository.
I thought I had integrated 8 MHz DIP-14 oscillator, turned out I did not. It also proved not that easy to buy. But I had 8 MHZ HC49-SD crystals, so I decided to design a replacement. This PCB should allow usage of pretty much whichever crystal, but R1, R2, C1 and C2 should be picked accordingly.
