3DPCB-4LAYER: common questions
What microcontroller does the 3DPCB-4LAYER use?
The 3DPCB-4LAYER is built around the LPC1768_TQFP100, from the NXP family.
How big is the 3DPCB-4LAYER PCB?
The 3DPCB-4LAYER measures 100 × 60 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the 3DPCB-4LAYER?
200 components, from 58 distinct parts. The full bill of materials is listed on this page.
Where can I download the 3DPCB-4LAYER design files?
From the ChristianLerche/3DPCB-4LAYER repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the 3DPCB-4LAYER design in my own project?
The repository has no license, so all rights stay with ChristianLerche. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the 3DPCB-4LAYER without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
