Questions
How big is the Digital Potentiometer Module PCB?
It measures 49.5 × 59.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Digital Potentiometer Module use?
22 parts, built around the ESP32-WROOM-32E, AD5231BRUZ10 and EG1218. 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 Digital Potentiometer Module KiCad files?
From the ikok07/esp32_digital_potentiometer_pcb repository on GitHub, at the commit this page was made from: the board is Digital Potentiometer Module.kicad_pcb and its schematic Digital Potentiometer Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Digital Potentiometer Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask ikok07 before reusing the design.
