DC 5V yekupinda inoshanda zvakanyanya kune yakaderera kusvika pakati-magetsi zvishandiso. Kune epamusoro-simba maapplication, iwe ungangoda yakakwira voltage mapipu kana nyanzvi dzesimba manejimendi masisitimu. Gara uchiverenga simba redunhu rako usati wapedza kugadzira.
Ndezvipi zvishandiso zvinobatsira mukugadzira DC 5V yekuisa PCB?
Zvishandiso zvakaita seKiCad, Gondo, kana Altium Mugadziri anobatsira mukugadzira dhizaini yedunhu uye PCB marongero. Multimeters uye oscilloscopes akakosha pakuyedza kugadzikana kwemagetsi uye ruzha. Zvishandiso izvi zvinovimbisa kuti dhizaini yako inosangana nekuita uye kuvimbika zviyero.
Sei uchifanira kusarudza Wonderful PCB yeDC 5V yekuisa PCB kugadzira?
Wonderful PCB inopa akavimbika ekugadzira masevhisi akagadzirirwa DC 5V ekuisa madhizaini. Nekukurumidza prototyping, yakasanganiswa dhizaini ongororo, uye yemhando yepamusoro gungano, unogona kutarisa kune hunyanzvi ivo vachibata kugadzira. Unyanzvi hwavo hunoita kuti PCB yako ikwane kuita uye kusimba zvinodiwa.
muromo: Kushanya Wonderful PCBWebhusaiti yekuongorora masevhisi avo uye kutanga chirongwa chako nhasi!
