Technical Summary
The Bitland Wheelie motherboard is built on the Intel Jasper Lake platform, revision 1.0, dated March 15, 2021. The system is managed by an IT8320 EC with 512KB of internal flash memory. The main BIOS is stored on a 32MB PCH SPI ROM, specifically the GD25Q256DWIGR model. Memory architecture consists of LPDDR4x configured as 29332x32. Audio processing is handled by an ALC5682 codec paired with ALC1015 amplifiers. Wireless connectivity is provided by an AX201 module supporting 802.11ac and Bluetooth 5.0. The board features a GL9755 card reader, an IT5205 USB hub, and a PS8203 USB redriver. Display output is managed by a PS8407A HDMI level shifter. USB-C charging is controlled by a BQ24800 charger IC paired with an RAA489000 USB-C controller. Storage options include eMMC in 32GB, 64GB, or 128GB capacities. The system also integrates an LSM6DS3TR IMU, LIS2DWLTR accelerometer, AH1389 hall sensor, and N24C02 EEPROM.
