2. Development Board Operation Instructions

2.1 Acquiring Log with Onboard USB to UART Converter

P0_3 is default log output pin. UART conversion chip on board can transmit log to PC after J15 and J17.1 are
connected.
Connection of Jumper for Log Test is shown in Figure 2-1.

2.2 Current test

The following current test points are reserved on evaluation board:
 VDD_DEV is peripheral power supply of EVB.
 VDD_BAT powers VBAT and HVD on EVB.
 VDD_IO powers VDD_IO on RTL8762C chips (some of packages have no independent VDD_IO Pin)
J23 shall be disconnected when testing power consumption.
Notes:
 Log output in the SDK shall be disabled during current measurement to avoid additional power
