Icyiciro cya API 5L X52
Bitewe n'urwego rwa PSL n'uko imodoka ihagaze, X52 ishobora gushyirwa mu byiciro bikurikira:
PSL1: X52;
PSL2:X52N cyangwa L360N;X52Q cyangwa L360Q;X52M cyangwa L360M.
Muri PSL2, inyuguti y'inyuma yerekeza ku bwoko bw'ubushyuhe ibikoresho bigomba gukorerwaho mbere yo kubigeza burundu. Urashobora kubonaimiterere y'ibyo umuntu ashobora gutangahepfo kugira ngo umenye byinshi.

Uburyo bwo gukora API 5L X52
Imiyoboro ya X52 ishobora gukorwa hakoreshejwe uburyo butandukanye bwo gukora imiyoboro kugira ngo ihuze n'ibikenewe mu buhanga butandukanye.
Kugira ngo umenye byinshi ku bijyanye n'igisobanuro cy'incamake y'inzira yo gukora,kanda hano.
