12 Layout

12.1 Layout Guidelines

The I2C signals (SDA / SCL) should be kept away from potential noise sources.

The traces carrying power through the LEDS should be wide enough to handle the necessary current.

All LED current passes through the device and into the ground node. There must be a strong connection between the device ground and the circuit board ground. For the RGY package, the thermal pad should be connected to ground to help dissipate heat.
