D75-FilamentExtruder: common questions
What microcontroller does the D75-FilamentExtruder use?
The D75-FilamentExtruder is built around the ESP32-DevKitC, from the ESP32 family.
How big is the D75-FilamentExtruder PCB?
The D75-FilamentExtruder measures 91.8 × 100.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the D75-FilamentExtruder?
24 components, from 14 distinct parts. The full bill of materials is listed on this page.
Where can I download the D75-FilamentExtruder design files?
From the LMHDPRO/D75-FilamentExtruder repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the D75-FilamentExtruder design in my own project?
Yes, under the terms of its MIT license, which LMHDPRO chose for the repository.
Can I test firmware for the D75-FilamentExtruder without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
