This board embeds a SIP (single core 533MHz ARM926EJ-S with 64MB DDR) with AXP173 PMIC, IO headers and microSD/eMMC storage. The board is also compatible with the smaller F1C100s that only embedds 32MB DDR RAM.
Note: The uC has two SDIO controllers (SDIO0 - 4bit wide, SDIO1 - 1bit wide). SDIO0 is used for SDCard. To provide wireless networking, while not sacrificing a large amount of pins, a design decision was made to use ESP32 module to provide WiFi/BT capabilities connected via SPI bus, leveraging ESP_HOSTED_NG as a solution.
