The GYD-9E is a universal LED driver board (step-down constant current converter) commonly used for replacing CCFL backlights with LED strips in 15-24 inch LCD monitors. It is built around the DF6113 PWM controller IC. Key Specifications Controller IC: DF6113 (Step-down PWM converter). Input Voltage Range: 10V – 30V DC. Board Dimensions: Roughly 5cm x 7cm.
Unlike bare MPU-9250 chips (which are strictly 3.3V), the GYD-9E includes a LDO voltage regulator. This allows 5V operation, but note the logic level remains 3.3V. Arduino’s 5V logic is generally safe due to 5V tolerance on SDA/SCL, but using a level shifter is best practice for long-term reliability. gyd-9e datasheet
