Lenovo AIO 520-24IKL LA-E881P Schematic
Technical Specifications
Technical Summary
This Compal LA-E881P is an All-in-One motherboard designed for the Intel Kaby Lake-S platform with an LGA1151 socket, paired with an AMD GPU (M17) and a B250 PCH. The system memory architecture consists of two DDR4-SO-DIMM slots supporting dual-channel configuration. The main BIOS SPI flash is an 8MB W25Q64FVSSIQ, while the EC firmware is stored on a separate 128KB W25X20CLSNIG SPI ROM, managed by the NCT6685D EC. Audio is handled by a Realtek ALC274 codec, and networking is provided by a Realtek RTL8111G LAN IC. The board also features a Realtek RTS5170 card reader, an Anpec APA6003 audio amplifier, and an RTD2136R HDMI level shifter with an RTD2506S-CG HDMI converter. Optional TPM support includes Nuvoton NPCT650LBBYX, Infineon SLB9670VQ2.0, or ST ST33HTPH2E32AHA6.
