Dhau li ntawm lwm cov haujlwm, nws muaj 6-channel MultiCeiver ™ feature, uas tso cai rau siv nRF24L01+ hauv lub hnub qub network topology. Lub nRF24L01+ siv SPI interface los sib txuas lus nrog tus tswv tsev MCU. Raws li SPI kab, nws siv GPIO pins ntxiv rau SPI Chip Xaiv, Chip Enable, thiab rau kev cuam tshuam. RF ntu ntawm mikromedia 5 FPI kuj tseem muaj cov kav hlau txais xov me me (4) nrog rau SMA txuas rau cov kav hlau txais xov sab nraud.

WiFi

Ib qho nrov WiFi module (2) sau npe ua CC3100 tso cai rau kev sib txuas ntawm WiFi. Cov qauv no yog qhov ua tiav WiFi kev daws teeb meem ntawm lub nti: nws yog lub zog WiFi network processor nrog lub zog tswj kev tswj hwm, muab TCP / IP pawg, muaj zog crypto cav nrog 256-ntsis AES kev txhawb nqa, WPA2 kev ruaj ntseg, SmartConfig ™ thev naus laus zis, thiab ntau yam. ntau. Los ntawm kev tshem tawm cov haujlwm ntawm WiFi thiab Is Taws Nem los ntawm MCU, nws tso cai rau tus tswv tsev MCU los ua cov ntawv thov ntau dua graphical, yog li ua nws qhov kev daws teeb meem zoo tshaj plaws rau kev ntxiv WiFi txuas rau mikromedia 5 FPI. Nws siv SPI interface los sib txuas lus nrog tus tswv tsev MCU, nrog rau ob peb ntxiv GPIO pins siv rau kev rov pib dua, hibernation, thiab rau kev ceeb toom cuam tshuam.

Ib qho SMD jumper sau tias yog FORCE AP (3) yog siv los yuam CC3100 module rau hauv Access Point (AP) hom, lossis mus rau hauv Chaw Nres Tsheb. Txawm li cas los xij, hom kev ua haujlwm ntawm CC3100 module tuaj yeem hla dhau los ntawm software.

Qhov no SMD jumper muaj ob txoj kev xaiv:

• 0: FORCE AP tus pin raug rub mus rau qib qis logic, yuam CC3100 module rau hauv STATION hom
• 1: FORCE AP tus pin yog rub mus rau HIGH logic theem, yuam lub CC3100 module rau hauv AP hom Muaj ib lub kav hlau txais xov nti (4) kev koom ua ke ntawm PCB ntawm mikromedia 5 FPI nrog rau SMA connector rau sab nraud WiFi kav hlau txais xov.

mikroBUS™ shuttle connectors

Mikromedia 5 rau STM32 RESISTIVE FPI kev txhim kho pawg thawj coj saib siv mikroBUS ™ Shuttle connector, ib qho tshiab ntxiv rau mikroBUS ™ tus qauv hauv daim ntawv ntawm 2 × 8 tus pin IDC header nrog 1.27mm (50mil) suab. Tsis zoo li mikroBUS ™ sockets, mikroBUS ™ Shuttle connectors siv qhov chaw tsawg dua, tso cai rau lawv siv nyob rau hauv cov ntaub ntawv uas yuav tsum tau compact tsim.

Suab hais txog peripheral

Los ntawm kev muab ib khub ntawm lub suab hais txog cov khoom siv, mikromedia 5 FPI hloov kho nws lub tswv yim multimedia. Nws nta lub piezo-buzzer, uas yooj yim heev rau kev pab cuam tab sis tuaj yeem tsim cov suab yooj yim, tsuas yog siv tau rau lub tswb lossis ceeb toom. Qhov kev xaiv thib ob yog lub zog VS1053B IC (1). Nws yog Ogg Vorbis / MP3 / AAC / WMA / FLAC / WAV / MIDI audio decoder, thiab PCM / IMA ADPCM / Ogg Vorbis encoder, ob qho tib si ntawm ib nti. Nws nta cov tub ntxhais muaj zog DSP, zoo A / D thiab D / A converters, lub tso suab lub mloog pob ntseg tsav tsheb muaj peev xwm tsav lub 30Ω load, zerocross nrhiav tau nrog lub ntim du, bass thiab treble tswj, thiab ntau ntxiv.

Piezo buzzer
Lub piezo buzzer (2) yog ib qho cuab yeej yooj yim uas muaj peev xwm rov tsim suab. Nws yog tsav los ntawm me me pre-biased transistor. Lub buzzer tuaj yeem tsav los ntawm kev siv lub teeb liab PWM los ntawm MCU ntawm lub hauv paus ntawm lub transistor: lub suab ntawm lub suab nyob ntawm qhov zaus ntawm PWM teeb liab, thaum lub ntim tuaj yeem tswj tau los ntawm kev hloov nws lub luag haujlwm. Txij li thaum nws yooj yim heev rau kev pab cuam, nws tuaj yeem muaj txiaj ntsig zoo rau lub tswb yooj yim, cov ntawv ceeb toom, thiab lwm hom kev teeb tsa suab yooj yim.

Audio CODEC

Kev xav tau thiab cov haujlwm ua haujlwm nyuaj tuaj yeem raug tshem tawm los ntawm tus tswv MCU los ntawm kev siv lub suab CODEC IC, sau npe VS1053B (1). Qhov IC no txhawb nqa ntau hom suab sib txawv, feem ntau pom muaj nyob ntawm ntau yam khoom siv digital. Nws tuaj yeem encode thiab txiav txim siab lub suab ntws ntawm nws tus kheej thaum ua haujlwm DSP ntsig txog kev sib txuas. VS1053B muaj ob peb yam tseem ceeb uas ua rau qhov IC no nrov heev thaum nws los txog rau kev ua suab.

Los ntawm kev muab cov cuab yeej zoo siab compression (encoding), VS1053B tso cai rau lub suab kaw tau siv ntau qhov chaw tsawg dua piv rau tib cov ntaub ntawv suab hauv nws hom raw. Ua ke nrog cov khoom zoo ADCs thiab DACs, headphones driver, integrated audio equalizer, volume control, and more, nws sawv cev rau txhua qhov kev daws teeb meem rau txhua hom kev thov suab. Nrog rau cov txheej txheem ua haujlwm muaj zog, VS1053B audio processor ua tiav tag nrho cov khoom sib txuas ntawm mikromedia 5 FPI kev txhim kho pawg thawj coj saib. Lub mikromedia 5 FPI board yog nruab nrog 3.5mm plaub-ncej headphones jack (3), tso cai rau txuas lub mloog pob ntseg nrog lub microphone.

Sensors thiab lwm yam peripheral

Ib txheej ntawm cov khoom siv ntxiv onboard thiab cov khoom siv ntxiv ntxiv lwm txheej ntawm kev siv tau rau mikromedia 5 FPI kev txhim kho pawg thawj coj.

Digital motion sensor
Lub FXOS8700CQ, ib qho kev sib xyaw ua ke 3-axis accelerometer thiab 3-axis magnetometer, tuaj yeem ntes ntau yam xwm txheej cuam tshuam txog kev txav, suav nrog cov xwm txheej kev taw qhia, kev tshawb pom kev poob siab, kev tshawb nrhiav kev poob siab, nrog rau kais, thiab ob-kais qhov xwm txheej nrhiav pom. Cov xwm txheej no tuaj yeem tshaj tawm rau tus tswv tsev MCU dhau ob lub siab cuam tshuam tus pins, thaum cov ntaub ntawv hloov pauv tau ua dhau ntawm I2C kev sib txuas lus interface. FXOS8700CQ sensor tuaj yeem pab tau zoo rau kev pom kev taw qhia. Nws kuj tseem siv tau los tig mikromedia 5 FPI rau hauv 6-axis e-compass tov. I2C qhev chaw nyob tuaj yeem hloov tau los ntawm kev siv ob lub SMD jumpers pawg hauv qab ADDR SEL daim ntawv lo (1).

Lub sijhawm-sijhawm (RTC)

Tus tswv tsev MCU muaj lub sijhawm tiag tiag moos peripheral module (RTC). RTC peripheral siv cov khoom siv hluav taws xob sib cais, feem ntau yog lub roj teeb. Txhawm rau tso cai rau kev taug qab mus tas li ntawm lub sijhawm, mikromedia 5 FPI tau nruab nrog lub pob ntawm tes roj teeb uas tswj hwm RTC kev ua haujlwm txawm tias lub zog tseem ceeb yog OFF. Kev siv hluav taws xob tsawg heev ntawm RTC peripheral tso cai rau cov roj teeb no kav ntev heev. Lub mikromedia 5 FPI txoj kev loj hlob board yog nruab nrog lub pob xov tooj ntawm tes roj teeb tuav (2), sib xws nrog SR60, LR60, 364 khawm ntawm tes roj teeb hom, tso cai rau nws suav nrog lub sijhawm tiag tiag hauv cov ntawv thov.
