PAS
About the PAS PCB
PAS is an open source PCB design by Rowson3D, published on GitHub under the MIT license. It is a 2-layer board measuring 76.2 × 49.5 mm, with 22 components from 12 distinct parts.
Other key parts include the LF353, TMUX1237_FFRV and TLV3501_8. By type, the board carries 8 resistors, 6 ICs and 2 capacitors.
From the project
Team 18 - SDSU Capstone project - FFRV
The FFRV system will be a test box used for measuring the frequency response of a user-provided passive filter. Once started, the system will apply a frequency sweep across an inputted filter, then measure the filter output gain and phase shift using analog computations, inputted to an Arduino Due microcontroller. Thus, this FFRV system will calculate the Bode plots for a real-world filter. The purpose of the FFRV system is to allow students, hobbyists, and other casual filter-designers a rapid way to gain insight into simple filters, such as what frequencies they pass or reject. As such, the…
