ARDUINO RFLINK-Whakaranuhia te UART Ahokore ki te I2C Module 
Ko te RFLINK-Mix Wireless UART-to-I2C he huinga ahokore ngawari ki te whakamahi e taea ai e nga kaiwhakamahi te whakarite tere i nga taputapu I2C. Kaore koe e hiahia ki te hono i nga taura roa mai i te tauranga I2C o te kaihautu ki nga taputapu I2C takitahi. Me hono noa koe i te UART ROOT o te RFLINK-Mix ki te atanga UART o te mana matua (Arduino, Raspberry Pi, tetahi atu HOST) , me nga taputapu I2C SLAVE ki te RFLINK-Mix i te taha o te I2C Master, he UART ahokore. kua reri te punaha to-I2C ki te haere.
Te ahua me te rahi o te waahanga
Kei roto i te kōwae RFLINK-Mix UART-to-I2C tetahi wahi o te UART ROOT (maui) tae atu ki nga wahanga e wha Ko te taha o te Pūrere I2C (ko te RFLINK-Mix I2C kōwae te Kaiwhakaako–te taha matau o te ahua i raro nei, te nama 0 ~ 3). He rite tonu te ahua o nga momo e rua, engari ka taea te tautuhi ma te pouakataki o te tapanga kei muri.
Ka rite ki te whakaatu i te ahua i raro nei, ko te taha maui ko te taha waahanga, ko etahi atu ko te taha tapanga Ko te Wāhitau Rōpū o tenei roopu o RFLINK-UART ROOT modules ko 0001, reiti baud 19200. RFLINK I2C Device is Device 0 (CLK 1.4 M), Pūrere 1 (CLK 400K), Pūrere 2 (CLK 400K), Pūrere 3 (CLK 100K). , Ko te wahitau roopu ko 0001, Ka taea te kowhiri i te Karaka i te wa o te hoko
Ngā āhuatanga kōwae
- Mahi voltage: 3.3 ~ 5.5V
- Auautanga RF: 2400MHz ~ 2480MHz.
- Te whakapau kaha: 24 mA@ +5dBm i te aratau TX me te 23mA i te aratau RX.
- Te mana tuku: +5dBm
- Te tawhiti tuku: tata ki te 80 ki te 100m i te waahi tuwhera
- Reiti Baud(UART ROOT):9,600bps, 19,200bps ranei
- Karaka(I2C MASTER) : 1.2M/750K/400K/200K/100K/50K/25K/12.5K. (400K Taunoa)
- Rahi: 25 mm x 15 mm x 2 mm (LxWxH)
- Ka tautokohia nga whakawhitinga 1-ki-1, 1-ki-maha ranei (tae atu ki te wha), ka whakamahia i roto i te aratau whakahau ina whakamahia te Whakahau 1-ki-maha te whiriwhiri ko tehea taputapu hei tuku. .
