Hav Guys… Nov yog kuv cov lus qhia tshiab.
Cov roj teeb hlwb tau siv hauv lub neej txhua hnub los ua lub zog siv hluav taws xob siv hluav taws xob.
Qhov tsis zoo ntawm lub xov tooj ntawm tes yog qhov ua haujlwm voltage. Lub roj teeb lithium raug ib txwm muaj qhov hluav taws xob ntawm 3.7 V tab sis thaum nws ntws nws mus qis li 2.8V thiab thaum nws them tas nws nce mus txog 4.2V uas cuam tshuam rau cov qauv siv hluav taws xob ib txwm uas ua haujlwm nrog kev tswj hwm 3.3V lossis 5V raws li kev siv hluav taws xob.
Yog li txhawb kev hloov pauv los rau hauv kev ua si uas yuav siv qhov sib txawv 2.8V rau 4.2V raws li qhov hluav taws xob nkag thiab tswj hwm nws mus tas li 3.3V lossis 5V. Hauv qhov kev sib tham no, peb yuav tsim tus nqi qis dua hloov pauv uas muab qhov hloov pauv tas li 5v los ntawm CR2032 ntawm tes. Qhov siab tshaj plaws tam sim no yuav yog 200ma uas zoo txaus rau lub zog feem ntau ntawm microcontrollers thiab sensors. Nws kuj tseem tuaj yeem siv ua lub zog thaub qab.
Kauj Ruam 1: Cov ntaub ntawv xav tau
85 BL8530-5V Booster IC (SOT89)
U 47uH Inductor
SS14 Diode (SMD)
U 1000uF 16V Tantalum capacitor (SMD)
● Npib Cell Holder
● USB Poj Niam Txuas
Kauj Ruam 2: CIRCUIT DIAGRAM
Daim duab qhia hluav taws xob ntawm 5V lub tshuab txhawb nqa lub zog yog raws li qhia hauv qab no. Lub plawv ntawm Circuit Court yog BL8530 IC uas muaj qhov hluav taws xob tso tawm ntawm 5V. IC xav tau tsuas yog lub capacitor, inductor thiab diode los ua haujlwm.
Kauj Ruam 3: PCB Tsim
Kuv tau tsim cov txheej txheem PCB siv EAGLE CAD cov cuab yeej. Koj tuaj yeem pom daim duab saum toj no.
Kauj Ruam 4: PCB FABRICATION
Kuv tau xa cov ntaub ntawv gerber mus rau www.lioncircuits.com kom tau txais kuv li PCB tsim.
Kuv pom zoo LionCircuits rau kev tsim qauv raws li kuv tuaj yeem tau txais kuv cov PCBs rau tus nqi qis thiab nrawm. Kuv tab tom qhia kuv cov ntaub ntawv Gerber ntawm no.

DC-DC Boost Converter MT3608: 6 Cov Kauj Ruam
DC-DC Boost Converter MT3608: Phau ntawv qhia no yuav qhia siv MT3608 txhawb kev hloov pauv kom muaj zog li cov cuab yeej xav tau qhov sib txawv sib txawv. Peb yuav qhia qhov twg yog hom roj teeb zoo tshaj plaws los siv nrog lub hloov pauv thiab yuav ua li cas thiaj tau txais ntau dua li ib qho tso tawm los ntawm tus hloov pauv
Yooj Yim DC - DC Boost Converter Siv 555: 4 Cov Kauj Ruam
Yooj Yim DC - DC Boost Hloov Siv 555: Nws feem ntau muaj txiaj ntsig hauv Circuit Court kom muaj hluav taws xob ntau dua. Tog twg los muab +ve thiab -ve txoj kab rau op -amp, tsav buzzers, lossis txawm tias txuas tsis tas xav tau lub roj teeb ntxiv
Esp8266 Raws Li Boost Converter Nrog Qhov Ua Tau Zoo Blynk UI Nrog Kev Tawm Tswv Yim Tswj: 6 Cov Kauj Ruam
Esp8266 Raws Li Boost Converter Nrog Qhov Zoo Tshaj Plaws Blynk UI Nrog Kev Tawm Tswv Yim Tswj: Hauv qhov haujlwm no kuv yuav qhia koj txoj kev muaj txiaj ntsig thiab ib txwm muaj txoj hauv kev yuav ua li cas nce qib DC voltages. Kuv yuav qhia koj yooj yim npaum li cas nws tuaj yeem tsim lub zog hloov pauv nrog kev pab ntawm Nodemcu. Cia peb tsim nws. Nws kuj tseem suav nrog lub vijtsam ntsuas hluav taws xob thiab kev tawm tswv yim
Ntxiv Tam Sim No Qhov Tshwj Xeeb rau Buck/Boost Converter: 4 Cov Kauj Ruam (nrog Duab)
Ntxiv Qhov Kev Txwv Tam Sim No rau Buck/Boost Converter: Hauv qhov haujlwm no peb yuav tau saib ze dua ntawm cov nyiaj ib txwm/txhawb kev hloov pauv thiab tsim qhov me me, txuas ntxiv uas ntxiv qhov txwv tam sim no rau nws. Nrog nws, pob/txhawb kev hloov pauv tuaj yeem siv tau zoo ib yam li qhov sib txawv ntawm lub rooj zaum raug tshem tawm lub zog. Le
