CubeSat EPS Battery Management Kit with ESP32 + LED
Simulate a Real CubeSat Electrical Power System: EPS Battery Management Kit with ESP32 MPPT & OLED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit lets you build a functioning Electrical Power System (EPS) for a simulated CubeSat, complete with maximum power point tracking (MPPT) to extract every milliwatt from the solar panel. You’ll integrate dual INA219 sensors to monitor energy flow and log data to an SD card for mission analysis — just like real satellite power subsystems. Whether you’re prototyping for a university rocketry team or advancing your embedded systems skills, this hands-on project brings space-grade power electronics to your workbench.
What You'll Build
You'll assemble a compact power management board that autonomously tracks the solar panel’s maximum power point, charges a LiPo battery safely, and delivers regulated voltage to a CubeSat payload (simulated via the OLED and logging module). The fully enclosed unit mirrors the form-factor constraints of satellite hardware, giving you a tangible, testable EPS module ready for integration with flight computers or other subsystems.
What You'll Learn
- Implement a Perturb & Observe MPPT algorithm on ESP32 for solar energy harvesting
- Simultaneously monitor current and voltage on both solar input and battery output with dual INA219 sensors over I2C
- Design a battery charge management circuit using a TP4056 module and LM2596 buck converter
- Log power metrics in real time to a MicroSD card with timestamped entries from a DS3231 RTC

Who This Kit Is For
B.Tech ECE/EEE students developing cubesat power subsystems for final-year projects, participants in Smart India Hackathon space challenges, ATL (Atal Tinkering Labs) mentors building advanced demos, and engineers at IIT/NIT/VIT/BITS Pilani designing prototype satellite payloads. If you need a hands-on EPS platform that demonstrates MPPT control, telemetry logging, and safe battery handling, this kit accelerates your learning by months.
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?
Open the AI companion on your phone to get real-time guidance on wiring, code, or debugging; you can also send photos via WhatsApp for direct human support.
Does this kit include instructions to write the MPPT code from scratch?
Yes. The AI companion provides fully commented ESP32 code implementing Perturb & Observe. It is explained line-by-line, so you understand the algorithm and can modify it for your own needs.
Can I use this EPS in a real high-altitude balloon or rocket launch?
This kit is designed for simulation and education; it teaches space power principles but is not flight-rated. Use it as a prototyping node to iterate toward a flight-qualified design.
I don’t have experience with PCB assembly — is that required?
No. The kit includes a PCB prototype board for through-hole soldering, a detailed schematic, and a wiring diagram. The soldering iron and solder are included, making it accessible to anyone with basic soldering skills.
INA219 monitors solar panel input and battery discharge. MPPT algorithm on ESP32 maximises energy harvest.
