Boardview for the ASUS PRIME Z490M-PLUS micro-ATX motherboard, revision 1.03, packed as a 357 KB RAR. Opened in a boardview program, it shows component placement and net connections on both sides of the PCB, which helps when measuring VCORE, VCCSA and memory voltages or searching for a shorted MLCC. It also helps locate the SPI BIOS chip for reflashing. ASUS prints the revision on the board silkscreen, so check that it reads 1.03 before relying on part positions and pinouts.
