MySat Firmware v1.4 Released
After many hours of coding, testing, debugging, and occasionally staring at oscilloscopes hoping they would reveal the secrets of the universe, we’re happy to announce the release of MySat Firmware v1.4.
π Release Date: June 22, 2026
What’s New?
π System Event Logging
MySat can now log system events and export them directly from the Web GUI. Because “something weird happened” is not a very useful engineering report.
π‘ Telemetry Frame Counter
Added telemetry frame counting to help monitor communications and data transmission.
ποΈ Mission Data Management
You can now clear mission data CSV files directly from the interface. Sometimes the best debugging tool is a clean slate.
π Web GUI Updates
Added a mission data logging status indicator so you’ll always know whether data is being recorded – or whether your satellite is silently judging you.
Release is available on our GitHub: https://github.com/MySatKit/MySatKit-Firmware
About That Radio Module Bug…
We’ve spent the last few weeks investigating an annoying issue where the radio module unexpectedly shuts down after several minutes when running on battery power.
The strange part? When powered via USB-C, everything works perfectly.
Our first suspect was the Arduino-based slave controller firmware. Like all good detectives, we followed the evidence, ran experiments, and interrogated every line of code.
The verdict: the firmware appears innocent.
Current evidence points toward a hardware-related issue. The investigation continues, and unlike certain space agencies in science fiction movies, we actually read the telemetry before declaring victory.
We’ll keep the community updated as we learn more.
What is MySat?
π°οΈ MySat is a STEM educational satellite platform for students, makers, researchers, and space enthusiasts who want to understand how real spacecraft work.
Instead of learning space engineering from slides and textbooks alone, MySat lets you build, program, operate, and troubleshoot an actual satellite system – complete with telemetry, communications, power systems, onboard software, and all the unexpected surprises that come with real hardware.
Because nothing teaches engineering faster than discovering a bug at 2 AM and realizing the satellite was right all along.
As always, thank you to everyone testing MySat and helping us make space engineering more accessible to the next generation of builders. But your MySat: https://www.mysatkit.com/product/my-sat-space-fan-kit/
