About the Psu PCB
Psu is an open source PCB design by OpenSiPM, published on GitHub under the MIT license. It is a 2-layer board measuring 23 × 22.2 mm, with 14 components from 10 distinct parts.
Other key parts include the LM2776, TPS72301DBVR and TPS79333DBVR. By type, the board carries 8 capacitors, 3 ICs, 2 resistors and 1 connector.
It belongs with the power & battery designs in this gallery.
From the project
Single channel silicon photomultipliers for high-speed fluorescence imaging
The OpenSiPM project aims to design high performance, low cost detectors for fluorescense microscopy.
The sipm-bias-control repository contains the KiCAD design files for a high dynamic range silicon photomultiplier (SiPM) transimpedance amplifier, power suppply, and bias generator designed by Eben Olson and Michael Giacomelli. The repository is organized into separate folders for each component, with bias-control-lt8362 containing the design files for the high voltage bias generator, power-supply/power-supply-alt containing two equivilent opamp power supply boards, and the tiav3_s1XXXX…
