The core module integrates the SpacemiT K1 SoC, PMIC, DDR, eMMC, the eth0 PHY, and wireless connectivity. The companion IO carrier board extends it by providing the eth1 PHY and exposing standard interfaces, including dual Gigabit Ethernet, MicroSD, two USB-A ports, a USB Type-C port, two PCIe M.2 slots, and a serial console. The board also has two I2C EEPROMs. One is on the core module, which stores factory manufacturing data and is marked read-only. The other is on the carrier board, which is shipped unprogrammed and left writable for evaluation purposes. Add initial support for UART console, eMMC, SD card, I2C, EEPROMs, PCIe, USB, and dual Ethernet interfaces.
