1. The clock speed of For Nextion Discovery series MCU is 64 MHz, which is more powerful than the Basic series. 2. Compared with Basic series, Discovery series has better MCU performance and adopts image compression technology. Compared with Basic and Enhanced, Discovery series can take more pictures under the same amount of flash memory. 3. The SD card slot is only used to update For Nextion firmware/HMI design. For Nextion NX3224F024 / NX3224F028 only supports FAT32 format. 4. You can develop HMI GUI projects through the free For Nextion Editor software, simple drag-and-drop components and simple ASCII text-based instructions will greatly reduce your HMI project development workload. 5. For Nextion solution is the best balance between cost and advantage HMI solution with low and reduced learning curve.
