On the PCB, this pad
connects to the first
pin of the L9110S
Single - chip microcomputer STC15W201S
Single-chip is inserted on the IC Block, the assembly IC base, we should pay attention to the IC Block has
a semi-circular small gap
This mounting gap should be aligned with the semicircular notch on the top of the PCB. Single-chip IC
insert into the seat, we must pay attention to the semi-circular chip on the gap should also be semi-
circular gap with the IC on the same direction.
After the completion of the installation of all the pictures for reference only
