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.
JP1 external power input only provides voltage to target chip. Supply external power to Vin or J2 can provide
5V to NU1 pin5 (5V) and 3.3V to NU1 pin4 (3VCC).
