    Product detailed description

    Modified version of the classic board ARDUINO Mega R3 with full integration of the ATmega2560 microcontroller and IO ESP8266 with 4MB flash memory and CH340G USB-TTL converter.

    It will find its place in projects that require a larger memory size and a higher number of I/O pins. You're not gonna be short on those. The board offers an incredible 54 digital pins (14 with PWM technology), 16 analogue pins, a micro USB connector and a Barrel Jack for powering from a battery, for example. The board is therefore suitable for anyone working on complex projects and wanting to control them with a single board.

    Specifications:

    Microcontroller ATmega2560 / ESP8266
    Crystal 16MHz
    Flash 256kB / 4MB
    GASH 8kB
    EEPROM 4kB
    USB - Serial Converter CH340G

    Skvělá deska. Ke zde zmíněné absenci datasheetu: také jsem chvíli tápal, ale v diskuzi to Martin Frajdl celkem jasně píše. V podstatě je to deska Mega2560, tj. souhlasí pinout a schéma Arduino Mega2560 + je tam ta ESP8266, která se dá použít samostatně (je připojená na pinheader na desce), popř. pomocí DIL switchů a přepínače RXD0/TXD0 - RXD3/TXD3 připojit k UART3 ATmega 2560. Myslím, že popisy přímo na desce jsou dostatečné. Ale uznávám, že to není úplně na první dobrou :-).

    Za mě velké mínus. Není tu datasheet k této desce a ocenil bych elektrické schéma. Marně tápu kam je zapojený WiFi modul. Dost by nám to ulehčilo práci.

    Dobrý den, mohu při progrmování esp8266 krmit desku pěti volty přes usb? Předem děkuji za odpověď.
    MF Avatar of author Zdroj 04/10/2022 08:20
    Dobrý den, ano, deska se napájí 5V z USB, nebo 6-12V z napájecího konektoru. A to i v případě programování ESP8266.

    Chapu dobre, ze diky ATmega2560+ESP8266 je mozne piny Arduino mega ridit jako obvykle a navic bezet jednoduchy server, se kterym lze komunikovat pres wifi?
    MF Avatar of author 20/04/2022 13:16
    Dobrý den, ano dá se to tak říci. Na desce jsou mikrokontrolery ATmega a ESP8266 a lze je provozovat i nezávisle na sobě. Hlavní I/O piny jsou propojeny jen na ATmega - klasické Arduino a ESP8266 je pouze spojené s ATmega pomocí UART portu. Lze tedy mezi těmito mikrokontrolery komunikovat pomocí tohoto rozhraní. I/O piny ESP8266 nejsou nikam vyvedeny.
