Muva nje onjiniyela bephrojekthi ye-Raspberry Pi benze isimemezelo sokuthi bakhiphe ikhadi le-Raspberry Pi Compute Module 3+ (CM3 +) kuthuthukisiwe.
Lona Yinguqulo ephathekayo yemodeli ye-Raspberry Pi 3 B +, eyenzelwe ifomu lememori yenothibhuku (I-DDR2 SODIMM, usayizi 67.6 x 30 mm) futhi iyahambisana namabhodi we-I / O akhishwe ngaphambilini (I-Compute Module IO Board).
Mayelana ne-Raspberry Pi Compute Module 3+
Ngonyaka odlule, i-Raspberry Pi Foundation yethule ibhodi le-Raspberry Pi 3B + nge-processor esheshayo ye-Broadcom BCM2837B0, iGigabit Ethernet, ne-802.11ac WiFi.
Ngakho-ke kuzoba nengqondo ukuthi isisekelo sinikeze ukuthuthuka kuma-Module abo we-CM3 Compute ngeprosesa ye-Broadcom BCM2837B0 futhi yilokho kanye abakwenzile ngokwethulwa kwe-Raspberry Pi 3+ Module Module ye- $ 25 nangaphezulu.
Le Raspberry Pi Compute Module 3+ entsha ifaka i-2837-bit BCM0B64 SoC (ARMv8, Quad Core, 1.4Ghz), efanayo ne-Raspberry Pi 3 B +.
Njengakwimodeli yeCompute Module 3 ngenhla, Usayizi we-RAM ngu-1GB, kepha usayizi we-Flash uyanda kusuka ku-4GB kuye ku-8GB, futhi izinketho ezine-16GB ne-32GB Flash ziyatholakala.
Isixhumi siyefana nezindawo ze-RAM ezikuma-laptops.
Ngaphezu kwesimanje se-SoC epuletini elisha ukulawula izinga lokushisa kuthuthukile.
Lapho izinga lokushisa kwe-chip lifinyelela ku-70 °, imvamisa isethelwe ku-1.4GHz, kepha uma izinga lokushisa lidlula u-70 °, imvamisa iyehla iye ku-1.2GHz futhi ne-voltage esetshenziswa ku-chip nayo iyancipha, okunciphisa ukuphumelela kwe izinga lokushisa lokusika (80 °).
Ibanga lokushisa elisebenzayo linwetshiwe futhi manje lisukela ku -20 ° C liye ku-70 ° C.
Izici
Kwethulwa izinhlobo ezimbili zeRaspberry Pi Compute Module 3+
Leli puleti elisha Iza ngezinhlobo ezimbili eyodwa okuyiLite version enesikhala sekhadi le-SD kanye nenguqulo ephelele ene-chip yememori ye-eMMC.
Izindleko zeCompute Module 3+ ene-8 GB Flash ngu- $ 30 ($ 16 GB - $ 35, $ 32 GB - $ 40), Lite version - $ 25.
Imidwebo namabhodi wezintambo ayatholakala ngaphansi kwelayisense yamahhala. Njengohlelo lokusebenza, iRaspbian inikezwa.
Kunezinhlobo ezine ezahlukile ze-Raspberry Pi Compute Module 3+ enezinketho ezihlukile zokugcina kanye nokwabelana ngemininingwane elandelayo:
- I-SoC - Broadcom BCM2837 B0 53 GHz Quad Core Cortex A1,2 processor eneVideocore IV GPU
- Imemori engu-1GB LPDDR2 SDRAM
- Isitoreji
- CM3+/Lite : Izimpawu zamakhadi we-SD ngokusebenzisa isixhumi se-SO-DIMM
- I-CM3 + / 8GB - 8GB eMMC flash
- I-CM3 + / 16GB - 16GB iMMC flash memory
- I-CM3 + / 32GB - 32GB iMMC flash memory
- Isixhumi se-pin-200 esine:
- I-48x GPIO
- 2x I2C, 2x SPI, 2x UART
- 2x SD / SDIO, 1x NAND interface (SMI)
- I-1x HDMI 1.3a
- I-1x USB 2.0 HOST / OTG
- I-1x DPI (isibonisi se-RGB esifanayo)
- Isixhumi esibonakalayo sekhamera ye-1x 4-lane CSI (kufika ku-1Gbps kulayini ngamunye), i-1x 2-lane interface ye-CSI yekhamera (kuze kufike ku-1Gbps ngomzila ngamunye)
- I-1x 4-lane DSI interface interface (kufika ku-1 Gbps kulayini ngamunye), 1x 2-lane DSI interface interface (kufika ku-1 Gbps ngomzila ngamunye)
- Ukunikezwa kwamandla: I-VBAT (2.5V kuya ku-5.0V) ye-BCM2837 processor core, 3.3V ye-PHY, UI ne-eMMC flash, 1.8V ye-PHY, IO ne-SDRAM, i-VDAC (2.8V typ.)
- Okwevidiyo eyinhlanganisela i-DAC, GPIO0-27_VREF & GPIO28-45_VREF (1.8 kuye ku-3.3V) yamabhange amabili e-GPIO.
Imodyuli yekhompyutha inzima ukuyisebenzisa ngaphandle kwamakhadi akhethekile e-I / O, kepha imodyuli yakhelwe ikakhulukazi hhayi ukusetshenziswa okuhlukile, kepha ukwenza lula ukuhlanganiswa kobuchwepheshe be-Raspberry Pi nemikhiqizo ehlukahlukene nokwenza amasistimu we-multimedia wezimboni nosetshenzisiwe.
Ngoxhumana nabo be-SODIMM, amandla, amachweba e-USB, amachweba amabili we-HDMI wokuxhuma izibonisi, namachweba amabili wokuxhuma amakhamera anikezwa, okuvumela ibhodi ukuthi lisetshenziselwe ukuhlanganiswa namathelevishini e-3D.
Isibonelo, Ukusekelwa kwama-Raspberry Pi Compute Modules sekuvele kusetshenzisiwe kuma-monitors wesikrini esibanzi se-NEC, esingaguqulwa sibe uhlelo oluzimele lwe-multimedia ngokuxhuma la mabhodi.
