From the project

CubeSat Power Analytics Unit

This repository contains the design and development files for the Power Analytics Unit of the TiSAT CubeSat project. The primary objective is to monitor and analyze the power consumption of various sensors integrated into the satellite.

Since the satellite is equipped with solar panels for battery charging, the power management logic accounts for both energy harvesting and consumption cycles to ensure balanced power distribution.

CubeSatPowerAnalyticsUnit: common questions

What microcontroller does the CubeSatPowerAnalyticsUnit use?

The CubeSatPowerAnalyticsUnit is built around the STM32L431KCUx, from the STM32 family.

How big is the CubeSatPowerAnalyticsUnit PCB?

The CubeSatPowerAnalyticsUnit measures 30 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CubeSatPowerAnalyticsUnit?

11 components, from 9 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the CubeSatPowerAnalyticsUnit design files?

From the Larion2003/CubeSatPowerAnalyticsUnit repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the CubeSatPowerAnalyticsUnit design in my own project?

The repository has no license, so all rights stay with Larion2003. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the CubeSatPowerAnalyticsUnit without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
