I'm an absolute beginner and just installing the rokit smart inventor V2 for the first time. I've downloaded the Arduino IDE, installed the add on files, downloaded the driver, set the board and the port (and almost each step needed troubleshooting). Now when I upload the ASCII Table, it gives me the following:

Arduino: 1.8.13 (Mac OS X), Board: "Rokit-SmartInventor-mega32_v2"

Sketch uses 3194 bytes (9%) of program storage space. Maximum is 32336 bytes.
Global variables use 273 bytes of dynamic memory.
avrdude: verification error, first mismatch at byte 0x002e
0x15 != 0x11
avrdude: verification error; content mismatch
avrdude: verification error; content mismatch

Please help–I'm trying to get started!
