Photobiomodulation Therapy Controller Variant 29 Kit with ESP32 + LED
ESP32 Photobiomodulation Therapy Controller Kit with Dose-Tracked Pulsed LED Sessions
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Take control of your wellness regimen with a custom-built photobiomodulation device that precisely delivers 850nm near‑infrared and 630nm red light at therapeutic frequencies. Whether you’re exploring light therapy for muscle recovery, skin rejuvenation, or circadian rhythm optimization, this kit provides the core controller to run clinician-grade pulsed protocols while logging every session for data-driven refinement.
What You’ll Build
A programmable ESP32‑based controller that drives high-power LED arrays through MOSFET switching, generating precisely timed light pulses. The device features an OLED display for real-time session feedback, an RTC for timestamped dose logging to a microSD card, and a regulated 12V power stage—all housed in a durable enclosure. You’ll emerge with a tool that not only runs therapy sessions but also archives exposure data for longitudinal tracking.
What You’ll Learn
- Designing MOSFET-driven LED pulsing circuits for high-current therapeutic arrays.
- Programming ESP32 to manage multi-wavelength PWM with real-time clock synchronization.
- Logging treatment parameters (pulse width, frequency, duration) to microSD for data analysis.
- Assembling a stable 12V buck-converted power supply and integrating safety diodes.

Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion provides real-time troubleshooting; you can also reach us on WhatsApp for personalized assistance within 24 hours.
Can I customize the therapy frequencies for my specific protocol?
Yes, the ESP32 code is fully modifiable. The AI companion can guide you through adjusting PWM parameters to match your desired pulse width and frequency.
Is this kit safe for long-term use on skin?
The high-power LEDs are designed for brief pulsed exposure; we recommend following established PBMT guidelines. The included documentation covers safe pulse durations and thermal management.
Do I need prior experience with MOSFET circuits?
The kit assumes familiarity with basic electronics; however, the AI companion provides step-by-step assembly instructions. Some soldering experience is beneficial.
