• The recommended voltage is 3.3V. The RF performance will be instable if the
operating voltage is under 2.5V.
• P indicates a power supply pin, I/O indicates an input/output pin, and AI/AO
indicates an analog input/output pin.
• If you have any special requirements on the light color controlled by the PWM
output, please contact Tuya business personnel.
