Technical Specifications
Technical Summary
This Lenovo Hera-1 motherboard, project code 4PD0LK010001, board number 19835-1, is built on the Intel TigerLake-UP4 ULT 9W platform. The system is managed by a MEC1503 Embedded Controller and utilizes dual 32MB SPI flash for BIOS and NIST support. Memory architecture supports LPDDR4X in either single-channel 4GB or dual-channel 8GB/16GB configurations. The charging subsystem is based on the BQ25710RSNR battery charger/selector. Audio is handled by a Realtek ALC3306-VA1-GR codec paired with TAS2770RJQR smart amplifiers. Wireless connectivity is provided by an Intel Harrison Peak 2 CNVi module. The USB-C subsystem includes TPS65994ADSN PD controllers, JHL8040R and JHL8010R retimers, and a TUSB1044RNQR redriver. Sensor integration includes an ST LSM6DS3HTR G-sensor and gyro, an ALPS HGDEM013A hall sensor, and a TC62D518FTG proximity sensor. The motherboard was designed by Wistron Corporation under document number A2196.
