Novost na tržišču. ESP8266 vsebuje 32bit RISC CPU 80MHz s strojno WiFi podporo. Programira se lahko v LUA, Micro Python in Arduino okoljih. Uporabite lahko katerekoli Arduino senzorje.
Za delovanje potrebuje samo zunanjo anteno, ki je pri večini modulov kar na tiskanem vezju.
WiFi IEEE 802.11 b/g/n Wi-Fi
WiFi zaščita: WEP, WPA/WPA2 ali brez
Delovanje kot: dostopna točka, sprejemnik ali oboje
Vgrajen TCP / IP protokol ki podpira max 5 TCP povezav.
Lastnosti procesorja:
32-bit RISC CPU
Delovna napetost: !!! 3V3 !!!
delovna frekvenca: 80 MHz*
64 KB RAM program(razširljiv z Flash)
96 KB RAM podatki
Zunanji "flash" - 512 KB do 4 MB
Strojna podpora: SPI, I2C, I²S, UART
ADC: 1x 10-bit
do 16 GPIO priključkov (odvisno od modula - opis spodaj)
Programiranje:
module z USB vmesnikom programiramo preko njega, za module brez USB priključka pa potrebujemo
PRENOSI:
USB gonilnik CH340 na ESP kontrolnih ploščah Prenos
AT firmware osnovna varianta s katero je opremljen modul ESP01 Firmware
NodeMcu www opis firmware flasher ESPlorer
Micro Python www instalacija
Arduino instalacija ESP v Arduino okolju.
Za bolj profesionalno uporabo priporočam uporabo Arduino okolja v Atmel studiu. Opis
Na vse ESP8266 module lahko naložite naprednejše verzije odprtokodne sisteme Tasmota, ESPurna , ESPEasy, HomieIot v katerih lahko brez poznavanja programiranja nastavite in krmilite npr. senzorje, releje in vse ostale naprave ki jih najdete v naši trgoovini.
Primerjavo teh sistemov najdete na tej povezavi.
