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 the handle necessary current.
All LED current passes through the device and into the ground node. The connection between the device ground
and the circuit board ground must be a strong connection.
