Gigabyte B550M S2H Rev 1.0 Schematic
Technical Specifications
Technical Summary
The Gigabyte B550M S2H motherboard, revision 1.0, is built on the AMD AM4 platform with a Promontory PCH/southbridge. The board utilizes an ITE LPC SIO IT8688E for EC/KBC functions and an ALC1220 HD Audio CODEC for audio. Power delivery is managed by an IR35201 controller paired with IR3555 power stages in a 4+2 phase configuration for VCORE and VCORE_SOC. Memory support includes four unbuffered DDR4 DIMM slots. Networking is provided by a Realtek RTL8111EP LAN IC, with an M.2 slot for wireless connectivity. The board includes an RTS5441 card reader controller and a TUSB321_A31 USB hub IC. The BIOS is accessed via an SPI interface.
