CubeSat EPS Kit with ESP32 & MPPT Solar Charger - Advanced Power Sim
CubeSat EPS Battery Management Variant 6 Kit with ESP32 & OLED - Simulate a Space-Ready Solar Power System
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Recreating the electrical power subsystem of a CubeSat is one of the most challenging and rewarding tasks in space electronics education. This kit lets you build a fully instrumented battery management and solar harvesting simulator around an ESP32, complete with two INA219 sensors that monitor solar panel input and battery discharge independently. You'll code a true maximum power point tracking algorithm that adjusts the buck converter to squeeze every milliwatt from a 6V panel, then log all parameters to a microSD with real-time clock stamps-exactly the workflow a satellite power engineer uses.
What You'll Build
A self-contained EPS simulator that reads solar panel voltage/current through INA219 #1, battery charge/discharge through INA219 #2, and runs an MPPT loop on the ESP32 to dynamically set the LM2596 buck converter's output for peak energy transfer. A 0.96-inch OLED displays live power stats, while the DS3231 RTC timestamps every data point written to the microSD module. The entire assembly fits inside the included enclosure, mirroring the constrained volume of a real CubeSat.
What You'll Learn
- Implement a perturb-and-observe MPPT algorithm in ESP32 C/C++ to track the solar panel's maximum power point under varying light
- Interface INA219 high-side current sensors over I2C for simultaneous, high-accuracy solar input and battery monitoring
- Configure an LM2596 buck converter for adjustable voltage regulation driven by ESP32 PWM to maximise harvested energy
- Build a timestamped data logger combining a DS3231 RTC and microSD module, creating CSV logs ready for analysis

Who This Kit Is For
Designed for advanced hobbyists, research scholars, and engineering students working on satellite power systems. This kit aligns perfectly with Smart India Hackathon hardware challenges, B.Tech ECE/EEE final-year projects, ISRO student satellite initiatives, and lab courses at IITs, NITs, VIT, BITS Pilani, and other institutions where hands-on power management experience is crucial. If you need a reliable, documented CubeSat EPS simulation platform without the overhead of sourcing and validating components, this kit delivers.
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?
Our AI companion walks you through every connection and code block; if you still need help, message us on WhatsApp and a senior builder will resolve it within hours.
Is this kit suitable for a college satellite or CanSat competition?
Absolutely. The MPPT monitoring and data logging directly demonstrate power budget management, a core requirement for CanSat and CubeSat design reviews. Many teams use this exact setup for their electrical subsystem prototype.
Do I need prior experience with MPPT or advanced coding?
Familiarity with Arduino IDE and basic electronics is assumed. Our AI companion provides the MPPT algorithm framework and explains each step, so you can adapt it even if this is your first energy harvesting project.
Can I modify the system for a different solar panel or battery?
Yes. The INA219s and buck converter settings are adjustable in code, and the companion guide shows you how to recalibrate for higher voltage panels or larger LiPo packs, making the platform reusable for future satellite experiments.
INA219 monitors solar panel input and battery discharge. MPPT algorithm on ESP32 maximises energy harvest.
