Mohato oa 4: Diy Version
Ke entse mofuta oa diy oa module ho latela potoloho e tloaelehileng ea database.
Ke sebelisitse 50k potentiometer leha database e re "boleng bo phahameng ba R-ISET ke 30K ohm".
Joalokaha u bona, potoloho ha e hloekile haholo ...
Nka be ke sebelisitse SOP8 ho DIP8 pcb kapa SOP8 ho DIP8 adaptara bakeng sa potoloho e ntle haholoanyane!
Ke tšepa ho arolelana gerber file haufinyane o ka sebelisa.
Mohato oa 5: Ke Tla U Bona Haufinyane!
Ke kopa u ntlohele maikutlo a hau ka maikutlo 'me u tlalehe liphoso tsa tekheniki le sebōpeho-puo!
Ntšehetse le merero ea ka sehokelong sena https://allmylinks.com/dariocose
Mosebetsi o motle!
Ke bone phoso e le 'ngoe ea sebōpeho-puo e ka bakang pherekano. Qetellong ea mohato oa 2 u re:
Joalo ka ha re bona ho tsoa videong, matla a potoloho ho tloha ho 30mAh ho isa ho ho feta 200mAh
Seo se lokela ho re "30 mA ho 200 mA."
Lentsoe mAh le bolela "milli".amps linako tsa lihora 'me ke tekanyo ea matla, eseng tekanyo ea hajoale. Limilione tse leshome le metso e mehlanoamps bakeng sa lihora tse 2 kapa 5 milliamps bakeng sa lihora tse 6 ka bobeli ke 30 mAh.
Taelo e ngotsoeng hantle e khona!
Kea leboha!
U nepile! Ke leboha keletso ea hau!
Ke lokisa hang-hang!
