1. Solder the resistor on ICEJPR1 (MCUVCC) depends on the target chip operating voltage.
2. Solder the resistor on ICEJPR2 (ICEVCC) depends on the ICE chip operating voltage.
3. Switch the SW3 to OFF.
4. Connect the external power supply to ICEJ3.
Table 3-10 presents all power models when supplies external power through Nu-Link2-Me. The Nu-
Link2-Me external power sources are highlighted in yellow.

To use Vin or J2 as external power supply source, please follow the below steps:
1. Switch the SW3 depends on the target chip operating voltage.
2. Remove the resistor on ICEJPR1 (MCUVCC).
3. Solder the resistor on ICEJPR2 (ICEVCC) depends on the ICE chip operating voltage.
4. Connect the external power supply to Vin or J2.
To use JP1 as external power supply source, please follow the below steps:
