Fanamarihana:
- Ny zana-tsipìka modules dia misaraka amin'ny module tranga.
- Ny tsimatra dia tokony hosintonina miaraka amin'ny 4.7K-10Kohms ho malefaka eo anelanelan'ny 3.14V sy 3.46V amin'ny mpampiantrano birao.
- Ny pin dia nosintonina ho VCCT miaraka amin'ny 4.7K-10KΩ resistor ao amin'ny module.
- Jereo ny tabilao SFF-8472 Rev12.2 10-2.
