Hello, I am building a Robot-System. For the drive parts I use an Arduino Uno. For the Arm and all other parts like 2 Cameras, EMIC2 Text to Speech, Voice recognition shield and Nextion display with Touchscreen I use an Arduino Mega2560. Until now all is working. My problem is, that I use about 85% of the SRAM. 5% more and the sysem will not work properly (i have tested it). So my Question is: Exist an Mega with more than 8 Kb SRAM? Can I use another board with more than 8Kb SRAM and nearly the same features like my Mega2560 has? Is it possible to change the SRAM? Exists a special shield for mey problem?
Please be so kind a send my an answer (with some good tipps, if possible).
Thank you very much.
