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.

• SW802 – Multifunction button/Push button to turn on/off the IS2066B EVB (MFB/PWR)

• SW803 – By default, this button is not configured in the EVB, can be configured using the UI tool

• SW804 – By default, this button is not configured in the EVB, can be configured using the UI tool

The following table provides the settings of mode selection switch (SW301) to configure the IS2066B in various

operating modes.
