Printalyzer - Main Board: common questions
What microcontroller does the Printalyzer - Main Board use?
The Printalyzer - Main Board is built around the STM32F446RET6, from the STM32 family.
How big is the Printalyzer - Main Board?
The Printalyzer - Main Board measures 188 × 110 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Printalyzer - Main Board?
136 components, from 50 distinct parts. The full bill of materials is listed on this page.
Where can I download the Printalyzer - Main Board design files?
From the dektronics/printalyzer-timer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Printalyzer - Main Board design in my own project?
