README
README.mdPoorlabs stimulus generator
A custom driver for Chrolis LED system from ThorLabs
This repository contains all the documentation needed to build a custom driver for a Chrolis LED system from Thorlabs.
Features:
- Synchronisation with 2 photon microscope blanking signal (or any other synchronisation TTL pulse)
- Synchronisation done via hardware, dispensing the need to include complicated logic on the microcontroller
- Based on ESP32 (uses BeeHive main breakout board)
- Set of stimuli provided. Based on Led Zappelin's code
Skills required:
- Coding (Arduino IDE / Micropython)
- Soldering
- Using a drill, screwdriver

Questions
How big is the Blanking board PCB?
It measures 95 × 82 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Blanking board use?
23 parts, built around the 74HC14, B4B-XH-A(LF)(SN) and B2B-XH-A(LF)(SN). 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 Blanking board KiCad files?
From the BadenLab/poorlabs_stimulus_generator repository on GitHub, at the commit this page was made from: the board is hardware/blanking_board/blanking_board.kicad_pcb and its schematic hardware/blanking_board/blanking_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blanking board 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).
