Microprocessor: ESP32-S3FN8 (Xtensa® 32-bit LX7 dual-core core processor, five-stage isakhiwo rack yombhobho, frequency ukuya 240 MHz).
SX1262 LoRa itshiphu node.
Uhlobo lwe-C ujongano lwe-USB, olunamanyathelo okhuseleko apheleleyo afana nevoltagumlawuli we-e, ukhuseleko lwe-ESD, ukhuseleko lwesekethe emfutshane, kunye nokhuselo lweRF. Kwibhodi ye-SH1.25-2 i-interface yebhetri, inkqubo yokulawula ibhetri ye-lithium edibeneyo (intlawulo kunye nolawulo lokukhutshwa, ukukhuselwa kwe-overcharge, ukubonwa kwamandla ebhetri, i-USB / ibhetri yamandla okutshintsha ngokuzenzekelayo).
I-onboard 0.96-intshi ye-128 * i-64 dot matrix ye-OLED isiboniso singasetyenziselwa ukubonisa ulwazi lokulungisa, amandla ebhetri kunye nolunye ulwazi.
I-WiFi edibeneyo, i-LoRa, kunye ne-Bluetooth triple-network connections, onboard Wi-Fi, Bluetooth-specific 2.4GHz metal spring antenna, kunye ne-IPEX (U.FL) egciniweyo ujongano lokusetyenziswa kwe-LoRa.
Edityanisiweyo CP2102 USB ukuya serial izibuko chip ukulungiselela inkqubo ukhuphelo lula kunye noshicilelo debugging ulwazi.
Inoyilo oluhle lwesekethe yeRF kunye noyilo lokusetyenziswa kwamandla aphantsi.
Ubungakanani bemveliso
Imiyalelo yokusetyenziswa
Le projekthi yenziwe ngokupheleleyo kwiprojekthi ye-ESP32. Ngesi siseko, siguqule iziqulatho zefolda "ezahlukeneyo" kunye ne "boards.txt" (yongeza inkcazo kunye nolwazi lwebhodi yophuhliso), okwenza kube lula kubasebenzisi (ingakumbi abaqalayo) ukusebenzisa iibhodi zophuhliso lwe-ESP32 eziveliswa yinkampani yethu.
1. Ukulungiselela i-Hardware
