Note
:
1. The Vin input voltage will be converted by voltage regulator UP2 to 5 V. Supplying external power to Vin or J2 can
provide 5 V to NU1 pin5 (5V) and 3.3 V to NU1 pin4 (3VCC).
2. JP1 external power input only provides voltage to target chip.
3. 0
Ω should be removed from ICEJPR1’s MCUVCC and 1.8 V / 3.3 V / 5 V.
4. 0
Ω should be soldered between ICEJPR2’s ICEVCC and 1.8 V / 3.3 V.
5. The ICE chip voltage should be close to the target chip voltage.
6. -: Unused
