Overview
PC driver is an open-source printed circuit board by Open-2-Photon-Microscope, from the Open-2-Photon-Microscope/pockel-cell-controller repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 98 × 57 mm with 28 parts on 19 nets, routed with 91 tracks and 3 vias.
It is built around the CA3240AE, LM10CLN and ADG419BNZ. Its parts include 7 resistors, 5 connectors, 3 capacitors, 3 ICs and 2 diodes.

README
README.mdPockel cell controller
An open source circuit to modulate laser intensity in a 2 Photon microscope. This modulation is necessary when visual stimulation is used to elicit responses from biological tissue (photoreceptors). The laser power is tunned high and low periodically (in our systems at 500Hz using a square wavefom at 80% duty cycle). When laser power is low, visual stimulation is on, when laser power is high, visual stimulation is off.
This driver was built to control a laser modulator from Conoptics. Specifically his model.
The main purpose of this circuit is to condition an analog signal using an fast switch IC that opens and closes the analog line using a digital 0-5V square signal (0V circuit open, 5V circuit closed). The original switching signal is 1.6ms at 5V and 0.4ms at 0V (composing a 500Hz signal), but other signals can be used.
This board can take an internal analog signal, where the signal amplitude (and therefore the laser intensity) is set by a potentiometer, or an external signal connected via a BNC cable.
The Pockels' cell driver was inspired by earlier devices designed and built by R. Berndt (HIH Tübingen), part of a project of T. Euler's lab.

Questions
How big is the PC driver PCB?
It measures 98 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PC driver use?
28 parts, built around the CA3240AE, LM10CLN and ADG419BNZ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PC driver KiCad files?
From the Open-2-Photon-Microscope/pockel-cell-controller repository on GitHub, at the commit this page was made from: the board is electronics/PC_driver/PC_driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PC driver design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
