Single stencil
About the Single stencil PCB
Single stencil is an open source PCB design by linuxboot, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 40.2 × 92.5 mm, with 20 components from 14 distinct parts.
Other key parts include the SPI Flash, W25Q128JVS and W25Q128JVP. By type, the board carries 5 capacitors, 5 resistors, 4 ICs, 4 connectors, 1 jumper and 1 switch.
