2.5 Voltage Selection Jump (JP3)
This is VDD Voltage Selection Jump, WLINK-SWUT can select three voltages when programming.
1. JP3 pad 1-2 short: means WLINK-SWUT can offer 3.3V voltage for SWUT programming and
development board.
2. JP3 pad 2-3 short: means WLINK-SWUT can offer 5V voltage for SWUT programming and
development board.
3. JP3 pad open: Using the power on the development board and offers SWUT voltage when on
programming (voltage range 2.2V ~ 5.5V)
