Fig 5.13 Bus1 LED Driver 16 channel Section
Operation of all sixteen LEDs at maximum current will overheat the LED Driver, which is protected by
an internal thermal limiter, the device will shutdown, and recover when the temperature has fallen.
When powered from the USB port (CN5) the USB Host is typically limited to 500mA, and it will shut
down before the LEDs reach maximum current. Operation from an external DC power supply
connection (CN6) is required to drive the LEDs to the maximum current per channel of 57mA, for a
total of approximately one amp.
The recommended AC-DC Adapter is Digikey PN: 62-1132-ND (Not Supplied) See figure 5.14

The Slave address is set by JP5, summarized in Table 5.
Note: The PCB is marked with Hex (8-bit) address data, but datasheets and the NXP GUI use the 7-bit
address values
. See table 5.1.
