The jumpers on the board are set as shown below. Items shown in gray are default settings.
3.1

Jumper switches

No.
JP1 +5 V input source power supply switching
JP3 CVDD input source power supply switching
JP4 VRIN (U06 internal regulator input) source switching
JP5 VBUS_5V_IN input source switching
JP16 VBUS output (CN7) switching
SW1 SPIxUART
SW2 HOSTxDEVICE
SW3 WAKEUP
SW4 INIT_BAUD
SW5 RESET SW
Note: If the CVDD level is a value above +1.8 V and below +5 V, remove the JP3 short pin and direct the
voltage to JP3 Pin 2. (+1.8 V to +5.0 V)
Note: If the VRIN level is a value above +3.3 V and below +5 V, remove the JP4 short pin and direct the voltage
to JP4 Pin 2. (+3.3 V to +5.0 V)
Note: If the signal is low asserted when SW2 (HOSTxDEVICE) and SW3 (WAKEUP) are connected to the
main CPU via CN9, SW2 and SW3 should be left open or R62 and R63 removed.
Note: Refer to "10.1 Exterior view diagram" for the jumper switch layout.
