Emisar D1K UV emitter fried itself. Bit of a bummer, but I've already reached out to Hank. Anyone else run into this with the 5W UV emitter?

Maybe a bad reflow giving poor heat conductivity to the MCPCB? Since the temperature is measured at the MCU, that could result in an LED overheating without the MCU going into thermal protection in time.
