QRET 25-26 SRAD Hybrid Lower Control Module: common questions

What microcontroller does the QRET 25-26 SRAD Hybrid Lower Control Module use?

The QRET 25-26 SRAD Hybrid Lower Control Module is built around the STM32F103CBT6, from the STM32 family.

How big is the QRET 25-26 SRAD Hybrid Lower Control Module?

The QRET 25-26 SRAD Hybrid Lower Control Module measures 69.5 × 60 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the QRET 25-26 SRAD Hybrid Lower Control Module?

140 components, from 67 distinct parts. The full bill of materials is listed on this page.

Where can I download the QRET 25-26 SRAD Hybrid Lower Control Module design files?

From the Queens-Rocket-Engineering-Team/av-prop repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the QRET 25-26 SRAD Hybrid Lower Control Module design in my own project?

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

Can I test firmware for the QRET 25-26 SRAD Hybrid Lower Control Module 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.
