Figure 3-6 External Power Supply Sources on M032BTAI Target Board
To use Vin or J2 as external power supply source, please follow the steps below:
1. Switch the SW2 depending on the target chip operating voltage.
2. Remove the resistor on ICEJPR1 (MCUVCC).
3. Solder the resistor on ICEJPR2 (ICEVCC) depending 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 steps below:
Switch the SW2 to OFF.
2. Remove the resistor on ICEJPR1 (MCUVCC).
3. Solder the resistor on ICEJPR2 (ICEVCC) depending on the ICE chip operating voltage.
4. Connect ICEJ3 to PC.
5. Connect the external power supply to JP1.
To use Vin or J2 as external power supply source with Nu-Link2-Me detached from NuMaker-
M032BTAI, please follow the steps below:
Switch the SW2 depending on the target chip operating voltage.
2. Detach the Nu-Link2-Me from NuMaker-M032BTAI.
3. Connect the external power supply to Vin or J2.
To use JP1 as external power supply source with Nu-Link2-Me detached from NuMaker-
M032BTAI, please follow the steps below:
Switch the SW2 to OFF.
