However, if you need something with a larger screen, the Waveshare ESP32-P4-WIFI6-Touch-LCD-10.1 is also supported, and features a 10.1-inch display with 1280\u00d7800 resolution and a 10-point capacitive touchscreen. The actual Mac OS resolutions used are 640\u00d7360 and 640\u00d7400, respectively, then scaled twice to the native resolution of the display.<\/p>\n<p>Highlights of the project:<\/p>\n<ul>\n<li>CPU \u2013\u00a0 Motorola 68040 emulation with FPU (68881) \u2014 2-3 MIPS<\/li>\n<li>RAM \u2013 Configurable from 4MB to 16MB;
