README
README.mdPressure-Controlled Perfusion System
A modular, open-source pressure-controlled perfusion system designed for the biomechanical characterization of corneal tissue. This system provides precise control over retrocorneal pressure and perfusion flow rate for ex vivo experiments.
🚀 Quick Start
- Hardware: Assemble the mechanical components and connect the electronics as per the
hardware/documentation. - Firmware: Flash the Arduino with the appropriate controller firmware from the
Controller/directory. - Software: Install Python dependencies and run the recommended dashboard.
bash pip install -r software/Dashboard_2/requirements.txt python software/Dashboard_2/app.py
📁 Repository Structure & Component Guide
Here is a breakdown of the key software components and their intended use:
| Component | Purpose | Recommendation |
|---|---|---|
Controller/Controller_1 | Firmware configured for the Variohm CIT3100 pressure sensor. | Use if your hardware uses the CIT3100 sensor. |
Controller/Controller_2 | Firmware configured for the Ceraphant PTC31B pressure sensor. | Recommended for systems with the PTC31B sensor. |
software/Dashboard_1 | Legacy version of the Python control dashboard. | For reference or specific use cases. |
software/Dashboard_2 | Enhanced version with improved data visualization and control. | Recommended for all new installations. |
🔧 Hardware Specifications
Key components used in this system include:
- Stepper Motor Driver: The TMC2209 driver module controls the NEMA 17 stepper motor, providing silent operation and advanced features like stealthChop2 for noiseless motion and spreadCycle for high-speed performance.
- Pressure Transducer: The Ceraphant PTC31B is a pressure switch with a ceramic, vacuum-tight measuring cell, used for safe monitoring of absolute and gauge pressure. It is suitable for measurements in gases, vapors, and liquids.

Questions
How big is the Perfusion Shield PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Perfusion Shield use?
25 parts, built around the TMC2209SILENTSTEPSTICK, BME680 and AS5048A. 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 Perfusion Shield KiCad files?
From the RamzanJamali/Perfusion_System repository on GitHub, at the commit this page was made from: the board is Perfusion_Shield/Perfusion_Shield.kicad_pcb and its schematic Perfusion_Shield/Perfusion_Shield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Perfusion Shield design in my own project?
Its repository states no licence, so its author keeps all rights: ask RamzanJamali before reusing the design.
