Questions

How big is the Fast pwm controller PCB?

It measures 72 × 72 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Fast pwm controller use?

102 parts, built around the ADA4851-4YRU, TLC3704IN and JUMPER3. 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 Fast pwm controller KiCad files?

From the dexterlb/led_controller repository on GitHub, at the commit this page was made from: the board is boards/high_power_lamp/fast_pwm_controller/fast_pwm_controller.kicad_pcb and its schematic boards/bundled_esp/encoder/encoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Fast pwm controller design in my own project?

Its repository states no licence, so its author keeps all rights: ask dexterlb before reusing the design.
