    Product detailed description

    Arduino The UNO R4 has a 32-bit ARM Cortex-M4F 48 MHz Renesas RA4M1 processor. The older R3 had an 8-bit ATmega328 processor. The new R4 is 3–16× faster and offers 32 kB SRAM, 256 kB flash, and an additional 8 kB flash for data.

    Dimensions and connectors remain the same as R3. The new power supply can be supplied at 7-24 V via the power connector or 5 V via USB-C. In addition, the R4 has a new 12-bit DAC and CAN bus support.

    The UNO R4 Minima board's operating voltage is 5 V, making it hardware compatible with UNO form factor accessories with the same operating voltage. Shields designed for previous UNO revisions are therefore safe to use with this board but are not guaranteed to be software compatible due to the change of microcontroller.

    Dobrý den, mám otázku na kompatibilitu této nové desky s displejem 3.5" 320x480 TFT displej, ILI9486, Arduino Uno shield Kód: LA141016. U desky Úno R3 se bojovalo s velikostí paměti a displej byl funkční. Dá se tato nová deska použít s tímto displejem ? Bude plně funkční?
    PK Avatar of author 17/07/2023 18:32
    Myslím že ne, aniž bych zkoumal datasheety obou, tak myslím že staré UNO mělo 5V logiku, vstupy, výstupy, nové UNO má logiku 3,3V Ale stačí když se podíváte na datasheet toho displeje, který je k dispozici také na těchto stránkách a uvidíte
