UM-TSS
About the UM-TSS PCB
UM-TSS is an open source PCB design by cmos-droner, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 91 mm, with 74 components from 26 distinct parts.
Other key parts include the TL072, 40106 and LM7805CT. By type, the board carries 26 capacitors, 23 resistors, 14 diodes, 6 ICs and 1 inductor.
From the project
This is a circuit by Jacob Watters (check the original block post), I just did the PCB-layout. In agreement with Jacob this is released here as open hardware. Hopefully you enjoy the project and maybe you can even improve it!
