The Curiosity-GX10000 (PIC64GX SoC Curiosity Kit) is a compact SoC
prototyping board featuring a Microchip PIC64GX SoC PIC64GC-1000.
Features include:
- 1 GB DDR4 SDRAM
- Gigabit Ethernet
- microSD-card slot
note: due to issue on some board, the SDHCI is limited to HS (High
speed mode, with a clock of 50MHz and 3.3V signals).
