Dummy
About the Dummy PCB
Dummy is an open source PCB design by linuxboot, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 29.8 × 40.6 mm, with 14 components from 9 distinct parts.
Other key parts include the W25Q128JVS and W25Q128JVP. By type, the board carries 6 capacitors, 5 ICs, 2 connectors and 1 jumper.
