    Product detailed description

    Modified version of the classic Arduino Uno rev. 3 board with full integration of the ATmega328 microcontroller and IO ESP8266 with 32MB flash memory and CH340G USB-TTL converter. All modules can work together or independently.

    This combination of two legendary boards is an ideal board for beginners as well as advanced users. Thanks to the USB port and integrated converter, programming both microcontrollers is a breeze. The board also offers a coaxial connector that can be used to power the board from a battery or AC adapter. On the software side, the Arduino is programmed via the integrated Arduino IDE development environment. The ESP8266 microcontroller gives the devkit the ability to communicate via WiFi.

    Naprostá spokojenost, zatím funguje podle očekávání. Je nutné si dávat pozor na špatné přepnutí desky a přepnutí výběru v Arduino IDE

    Oba čipy pracuji spravne. Pozor na krkolomne nastavivani prepinacu na desce dle toho zda chcete nahrat data do At nebo esp cipu, nebo zda maji oba bezet spolecne bez moznosti prehrani sketch. Na prvni hrani je lepsi wemos d1 mini. Nemusi se nic prepinat piny a i nahravani je rychlejsi. Ale pozor vetsinou se prodava s dirkami a ruznymi piny/konektory. Dobra je moznost volby, ale znamena to dopajeni. U wifi cipu zvazte vzdalenost od wifi routru a moznost pripojeni externi anteny s vetsim ziskem signalu. Pro ULV, provoz na baterky např. Pro pokojove stanice se zaznamem kvality ovzdusi se hodi spise desky s esp32. Odealne ty s optimalizaci spotreby energie, kde se lze dostat na rozni provoz na baterii.

    Jakým způsobem oba čipy (AT/ESP) sdílejí I/O porty v jednotlivých režimech provozu?
    Avatar of author Sdílení portů 25/08/2025 11:24
    Pak má tedy ESP omezený počet I/O pinů. Normálně 22, zde jen 12.
    KL Avatar of author Sdílení portů 25/08/2025 10:38
    Zdravím, . Každý čip má své vlastní piny, nic se nesdílí .

    Dobrý den, jakým konektorem se připojuje deska k počítači ?
    VH Avatar of author Dotaz 30/06/2025 07:18
    Dobrý den, deska se připojuje přes mikro USB.
    TE Avatar of author Jaký anténní konektor na ESP části 20/06/2024 08:55
    Dobrý den, ta wifina úplně citlivá není. Jaký je tam konektor pro připojení externí antény? Díky za váš čas.
    MF Avatar of author Jaký anténní konektor na ESP části 20/06/2024 09:50
    Dobrý den, konektor je U.FL/IPEX1

    Dobry den, jaky je rozsah napětí pro vstupní piny (Digital a analog)?
    KL Avatar of author Rozsah napětí na pinech 09/05/2024 11:37
    ESP má 3.3V logiku, Atmel 5V
    M Avatar of author 09/05/2024 11:35
    Resp. hledám desku s WiFi co bude mít rozsah do 5V, ne jen 3,3 :)
    PK Avatar of author nastaveni Arduino IDE 12/10/2022 11:13
    Dobrý den, dotaz začátečníka. Chci tuto desku používat jako normální Arduino Uno, jen s větší pamětí Flash - 4Mb. V popisu je popsáno jak nastavit přepínače. Jakou mám ale nastavit vývojovou desku v Arduinu IDE? Děkuji za odpověď. Pavel
    MF Avatar of author nastaveni Arduino IDE 13/10/2022 11:53
    Dobrý den, u této desky se jedná o chybu v popisu zboží, kterou jsme neprodleně opravili. Mikrokontroler ATMega328, který je na této desce osazený nedisponuje FLASH pamětí 4MB, ale pouze 32KB, stejně jako Arduino UNO.
