Integrated Circular Controller PCBA for Smart Air Purification: The R100 Series circular controller PCBA is an integrated electronic mainboard platform designed for residential and commercial air purifiers featuring round user interfaces. Powered by an industrial 32-bit MCU, the board integrates flexible AC/BLDC stepless motor drivers, high-voltage ESP pack control, UV-C module outputs, and multi-sensor buses (PM2.5, VOC, temperature, and humidity) into a compact layout with ESD protection. Full OEM/ODM custom tooling, firmware tuning, and Tuya/Matter IoT integration available.
