To use JP13/JP14/JP15 as external power supply source with Nu-Link2-Me separated from NuMaker-
M2354, please follow the steps below:
1. Switch the SW4 to OFF.
2. Separate the Nu-Link2-Me from NuMaker-M2354.
3. Connect the external power supply to JP13.
Figure 3-7 Separate the Nu-Link2-Me from NuMaker-M2354
Table 3-12 presents all power models when supplying external power through the M2354 target board.
The M2354 target board external power sources are highlighted in yellow.

Note
:
1.
The Vin input voltage will be converted by voltage regulator UP2 to 5 V.
2.
0Ω should be removed from ICEJPR1’s MCUVCC and 1.8 V / 3.3 V / 5 V.
3.
0Ω should be soldered between ICEJPR2’s ICEVCC and 1.8 V / 3.3 V.
4.
The ICE chip voltage should be close to the target chip voltage.
5.
JP13 external power input only provides voltage to the target chip. Supplying external power to Vin or J2 can
provide 5V to NU1 pin5 (5V) and 3.3V to NU1 pin4 (3VCC).
