Electronics development for wireless-connected lighting controls with battery backup, across three radio protocols, at Leviton Manufacturing.
Led electronics development for a family of connected lighting controls supporting BLE, Wi-Fi, and Zigbee, each with battery backup for continued operation during power loss.
Adding wireless radios to a compact in-wall lighting control introduced conducted and radiated EMI risk from the switching power supply, and each protocol brought its own debugging surface across I2C, UART, BLE, and NFC interfaces.
Optimized the power supply design to mitigate conducted and radiated EMI, and debugged complex system-level issues across I2C, UART, BLE, and NFC to bring each radio variant to production readiness.
Shipped BLE, Wi-Fi, and Zigbee-enabled lighting controls with battery backup, meeting EMI requirements across all three radio variants.
