LedDimmer: common questions
What microcontroller does the LedDimmer use?
The LedDimmer is built around the PIC12F1572-I/SN, from the PIC family.
How big is the LedDimmer PCB?
The LedDimmer measures 40 × 45 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the LedDimmer?
63 components, from 22 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the LedDimmer design files?
From the EBOThor/DTS_Board repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the LedDimmer design in my own project?
Yes, under the terms of its MIT license, which EBOThor chose for the repository.
Can I test firmware for the LedDimmer without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
