ZIP archive named only Amigo, roughly 970 MB in size, with no device, board number or file type stated in the name. The large size suggests a software package, firmware bundle or a collection of service files rather than a single schematic, but the contents cannot be determined from the name alone. Open it and review what is inside before use, scan executables for malware, and for any firmware found confirm the target model and board revision match exactly before attempting to flash a device.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @oficinacomputadores. Enginerys does not host this file.
