***Soldering sequence tips***: If you do not follow this sequence, you may not be able to weld smoothly! ! !
Step 1: Solder the SMD components in the white frame. After soldering, it is strongly recommended to use a multimeter to measure whether the decoy voltage is normal before proceeding to the next step of soldering.
 
 
 
step2: 15p female header, use nozzle pliers to trim the pins:
step3: First frame the chip components in red (if you don’t want to solder the LED, you can directly tin it), then frame the three buttons in white:
step4: 8p female header:
step5: The remaining buttons:
 
step9: The remaining 20p and 8p female headersstep10
