Alpha spectrometer v1: common questions
What microcontroller does the Alpha spectrometer v1 use?
The Alpha spectrometer v1 is built around the STM32G0B1KETx, from the STM32 family.
How big is the Alpha spectrometer v1 PCB?
The Alpha spectrometer v1 measures 63.1 × 45 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Alpha spectrometer v1?
134 components, from 80 distinct parts. The full bill of materials is listed on this page.
Where can I download the Alpha spectrometer v1 design files?
From the Maniak003/AlphaSpectrometr repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Alpha spectrometer v1 design in my own project?
The repository has no license, so all rights stay with Maniak003. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Alpha spectrometer v1 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.
