Lenovo Flex 2-14d - LF145M MB - 13287-1 - LF155M 13310 Schematic
Technical Specifications
Technical Summary
The Wistron LF145M-1 motherboard, project code 4PD00Y010001 and PCB number 13827, is built around the AMD Beema UMA/PX platform featuring an AMD Beema FT3b APU with integrated AMD GPU Jet-1 graphics supporting DX11, eDP, HDMI, and VGA DAC outputs. The system uses a single-channel DDR3L memory architecture with one DIMM slot. Power management is handled by a BQ24715RGRR PWM charger IC and multiple DC/DC converters including ISL62771HRTZ-T, SY8208DQNC, RT8207MZQW, RT8068AZQW, and RT9025-25ZSP. The embedded controller is an NPCE285GA0DX, and the audio codec is an ALC233. Connectivity includes an RTL8106E LAN IC, GL3213 card reader, and WLANs Bluetooth module. The board also features an SPI flash for BIOS storage and an LTDP1 HDMI level shifter.
