PmodSTEP na-enye mbanye ọwa anọ maka moto stepper site na ST L293DD. Ndị ọrụ nwere ike waya ụzọ abụọ nke ọwa n'usoro iji kwọọ ihe ruru 600mA nke ugbu a kwa ọwa ma nwee ike. view ọnọdụ ugbu a nke mgbaàmà GPIO site na set nke LEDs.

PmodSTEP na-eji onye ọkwọ ụgbọ ala anọ nke ST, L293DD, na-anya ụgbọ ala stepper na oke mmiri dị elu karịa bọọdụ sistemụ nwere ike na-enyekarị site na nsonaazụ mgbagha ha. A na-enye isi ihe nlele ule mpụga na LED maka nnwale dị mfe na nleba anya mgbasa ozi.
Mmekọrịta na Pmod
PmodSTEP na-ekwurịta okwu na bọọdụ nnabata site na GPIO protocol. Pmod a na-enye nkụnye eji isi mee maka moto 4-pin na 6-pin stepper. Moto Stepper na-arụ ọrụ site n'itinye ume nke eriri igwe gaa na polarị dị iche iche na-eme ka moto stepper tụgharịa. 4-pin stepper motors na-arụ ọrụ naanị na nhazi bipolar, na-achọ ka etinyere ntinye abụọ na eriri elektrọn ọ bụla na ọkwa mgbagha ziri ezi vol.tages iji kpalie eruba ugbu a n'ụzọ ziri ezi. Igwe nkụnye eji isi mee ihe nke 6-pin na Pmod a nwere ike ịdabere maka nhazi bipolar ma ọ bụ otu. Ntụtụ abụọ agbakwunyere na nkụnye eji isi mee a na-enye ntụtụ ike abụọ dị mma dị ka isi iyi nke ugbu a maka mgbe etinyere n'otu nsọtụ nke eriri igwe gaa na mgbagha dị ala.tagna ọkwa.
