ʻO NRF24L01 kahi puʻupuʻu transceiver chip hoʻokahi e hana ana ma ka hui ISM honua 2.4-2.5GHz. Loaʻa nā transceivers uʻole: Frequency generator Enhanced SchockBurstTM mode controller Power amplifier Crystal amplifier modulator Demodulator Output power channel koho a me ka protocol Hiki ke hoʻonohonoho ʻia ma o SPI interface Haʻahaʻa ka hoʻohana ʻana i kēia manawa, ʻO 9.0mA ka hoʻohana ʻana i kēia manawa ke 6dBm ka mana hoʻouna i ka mode transmit, 12.3 mA ma ke ʻano loaʻa, a ʻoi aku ka haʻahaʻa o ke ʻano hoʻohana i kēia manawa ma ke ʻano standby.

Wehe ISM band, nui 0dBm mana hoʻouna, laikini manuahi. Kākoʻo i ʻeono awāwa o ka loaʻa ʻana o ka ʻikepili

1. Haʻahaʻa hana uila: 1.9 ~ 3.6V Low hana uila
2. ʻO ka wikiwiki kiʻekiʻe: 2Mbps, ma muli o ka manawa pōkole o ka hoʻouna ʻana i ka ea, e hoʻemi nui i ka hanana collision ma ka uila uila (pololei hoʻonohonoho 1Mbps a i ʻole 2Mbps ka nui o ka hoʻouna ʻana i ka ea)
3. ʻO ka pinepine pinepine: 125 mau alapine e hoʻokō i nā pono o ka kamaʻilio multi-point a me ke kamaʻilio pinepine-hopping.
4. Li'ili'i loa: antenna 2.4GHz i kūkulu 'ia, nui li'ili'i, 15x29mm (me ka antenna)
5. Ka hoʻohana ʻana i ka mana haʻahaʻa: I ka hana ʻana i ke kamaʻilio ʻana i ke ʻano pane, hoʻemi nui ka hoʻouna ʻana i ka ea wikiwiki a me ka manawa hoʻomaka.
6. Uku noi haʻahaʻa: NRF24L01 hoʻohui i nā ʻāpana hana hōʻailona kiʻekiʻe kiʻekiʻe e pili ana i ka protocol RF, e like me: ka hoʻihoʻi hou ʻana o nā ʻikepili i nalowale a me ka hōʻailona pane maʻalahi, etc. Hiki ke hoʻopili ʻia ka SPI interface o NRF24L01 e ka hāmeʻa SPI port o ka MCU a i hoʻohālikelike ʻia e ke awa I/O o ka MCU, a aia kahi MCU i loko.
7. Maʻalahi e hoʻomohala: No ka mea ua hoʻohui piha ʻia ka papa loulou ma ka module, maʻalahi loa ka hoʻomohala ʻana. Hiki ke ho'omalu 'ia ka hana ho'iho'i 'akomi, 'ike 'akomi a me ka ho'ouna hou 'ana i nā pūke 'ikepili i nalowale, ka manawa ho'iho'i hou a me ka manawa e ho'ouna hou 'ia e ka lako polokalamu e mālama 'akomi i ka 'ikepili 'ikepili pane 'akomi hana 'a'ole i loa'a ka hō'ailona pane. Ma hope o ka loaʻa ʻana o ka ʻikepili kūpono, hoʻouna koke ka module i ka hōʻailona pane. ʻAʻole pono e hoʻolālā i ka ʻike o ka mea lawe i kahi ʻike alapine paʻa i kūkulu ʻia i loko o ka lako CRC ʻike hewa a me ka helu wahi-i-multipoint kamaʻilio ʻōlelo hoʻokele packet transmission error counter a hiki ke hoʻohana ʻia ka hana ʻike lawe no ka hoʻonohonoho hop alapine hiki ke hoʻonohonoho i ka manawa like ʻeono ka loaʻa ʻana o nā ʻōlelo aʻoaʻo, hiki iā ia ke wehe maʻalahi i ka loaʻa ʻana o ke kahawai maʻamau pin Dip2.54MM pitch interface, maʻalahi e hoʻopili i nā noi.
