5.2. External Power Supply and Precautions
Use an external power supply method
(Through the Power Management will power
regulator into 3V,
and then provided to HY16F3981 IC)
5.2.1. Use an external power supply step
Step1: Remove the EDM Line
Step2: By JP8 (+), JP9 (-) to provide external power supply.
(Input range VDD~9.0V
)
Step3: Press S4 switch (External power switch)
Through the Power Management will
power regulator into 3V,
and then provided to HY16F3981 IC
STEP1
STEP3
STEP2
Precautions:
Because Mini Link supplied power = 3.3V, so when want to use an external power
supply, be sure to remove EDM line, avoid voltage different voltages caused conflict.
