Questions
How big is the LedDimmer PCB?
It measures 40 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LedDimmer use?
67 parts, built around the PIC12F1572-I/SN, TPS561243DRL, VS-10MQ100HM3/5AT and BSS138. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LedDimmer KiCad files?
From the EBOThor/DTS_Board repository on GitHub, at the commit this page was made from: the board is HW/LED_Dimmer/LedDimmer/backup/LedDimmer.kicad_pcb and its schematic HW/CC_Debug/CC_Debug/CC USB hub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LedDimmer design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
