Description

MODUŁ WI-FI ESP-WROOM-02 ESP8266EX Espressif Moduł Wi-Fi ESP-WROOM-02 jest doskonałym dopełnieniem urządzeń oraz układów zbudowanych w oparciu o popularne mikrokontrolery (jak np. Arduino). Moduł ten pozwala rozszerzyć możliwości urządzeń o komunikację bezprzewodową - zarówno pracując jako klient, jak i jako punkt dostępowy. Ponadto obecny na płytce procesor poza obsługą modułu Wi-Fi, może wykonywać inne zadania, dzięki czemu moduł można wykorzystać jako samodzielny mikrokontroler z łącznością bezprzewodową. W wykorzystaniu dodatkowych możliwości kontrolera pomoże również zintegrowane 4 MB pamięci Flash. Całość można programować za pośrednictwem odpowiedniego interfejsu USB -> UART 3.3V przy użyciu środowiska Arduino IDE lub Eclipse IDE. Uwaga! W trakcie programowania oraz użytkowania modułu należy zwrócić uwagę na poziomy napięć układów logicznych. Moduł został zaprojektowany do użytku z napięciem na poziomie 3.3 VDC zarówno od strony zasilania urządzenia, jak i w warstwie logicznej. Dostarczenie na wejścia napięcia 5 VDC może spowodować trwałe uszkodzenie modułu. Obsługiwane standardy: IEEE 802.11 b/g/n Procesor: ESP8266EX Tryby pracy: Station / Soft AP / Station + Soft AP Typ anteny: Wewnętrzna Interfejs: UART 3.3 V, SDIO, HSPI, I2C, I2S, GPIO, IR Remote Control, PWM Zakres częstotliwości: 2.4 GHz Czułość odbiornika: 11b 11M : -91dBm, 11g 54M : -75dBm, 11n MCS7 : -72dBm Bezpieczeństwo połączenia: WEP / TKIP / AES, WPA-PSK/WPA2-PSK Temperatura pracy: -40 °C ... 85 °C Waga: 0.001 kg Wymiary: 20 x 18 x 2.8 mm Producent / Marka: Espressif Gwarancja: 2 lata
