Mawu Oyamba
ASR6601 ndi LoRa soc chip.
Mkati mwake imayendetsedwa ndi core ya Cortex M4 yokhala ndi pulogalamu ya Semtech's LoRa transceiver SX1262. Gawoli limatha kukwaniritsa 868 (ya EU) / 915Mhz frequency band kulumikizana. Gawoli limagwiritsa ntchito chipangizo cha LoRa chokhala ndi CLASS A, B,C protocol, DTU ndi ma protocol osiyanasiyana achinsinsi. Protocol ya Class A, B,C ndi protocol ya Lorawan yosakhazikika ndipo ndiyoyenera pachipata chathu. MCU mkati mwa gawoli ndi yamphamvu, yokhala ndi 48Mhz master frequency ndi 16kbytes Sram, 128k flash, ikupanga kudumpha kwakukulu mukuchita kuchokera ku ASR6505 yam'mbuyo. Pofuna kuchepetsa mtengo wa hardware, Open MCU chiwembu angagwiritsidwe ntchito mwachindunji mkati ndi wosuta popanda kuwonjezera MCU.
Kumverera kwakukulu kwa gawoli kumafika - 140dBm, mphamvu yotumizira kwambiri mpaka 14dBm@868MHz(ya EU) Band / 94dBuV/m@3m@915MHz Band.
Chofunika kwambiri:
- Kulandila kwakukulu kumafika -148dBbm
- Mphamvu yayikulu kwambiri ndi 14dBm@868MHz(ya EU) Band / 94dBuV/m@3m@915MHz Band.
- Kuthamanga kwakukulu kotumizira: 62.5kbps
- Zocheperako zogona: 2uA
- Maulendo apamwamba kwambiri: 48Mhz
- 16kbytes Sram, 128k Flash
