3.1 Hardware Features
The following sections provide detailed information on the IS2066B EVB components. To locate these components in
the IS2066B EVB, refer to
Figure 2-1 .
3.1.1 Power Supply
The IS2066B EVB can be powered by the following supplies:
• Li-ion battery (J201) – when using a battery input, mount a jumper on (JP202). Do not mount a jumper on
(JP201). JP201 is a provision for connecting a battery power source with 2.54 mm connector.
• USB (J701) – USB cable is connected to a PC, which provides 5V power for battery charging and testing
purposes.
3.1.2 USB Connectivity
The IS2066B EVB has one USB port (J701) that can be connected to a host PC using a micro-USB cable, where the
USB signals are converted to/from the UART by the serial converter MCP2200.
