Connect Hardware
Plug the TSL2521 Daughterboard into the Controller board (Figure 1). Always
use ESD procedures when handling the EVM.
Using the enclosed USB cable, plug the micro-B connector into the EVM module.
Using the other end of the cable, plug the USB A-connector into a USB port on
the computer.
When the USB cable is connected, the green LED should light on power up to
indicate that power is being received via the USB interface, and the
controller board processor is running. If the green LED does not light, check
the USB cable connections; unplug the USB cable and try again. If the green
LED still does not light, check the PC for USB error messages.
