The Chameleon board is an OpenHardware devboard made by YuzukiTsuru. The form factor resembles the Raspberry Pi Model A boards, though it differs significantly in its features:
- Allwinner H618 SoC (4 * Arm Cortex-A53 cores, 1MB L2 cache, 1.4 GHz) - between 512MiB and 2GiB DDR3 DRAM - up to 128 GiB eMMC flash - AXP313a PMIC - 100 Mbit/s Ethernet pins on a header - XR829 WIFI+Bluetooth chip - 4 * USB 2.0 USB-C ports - microSD card slot - 3.5mm A/V port Add the devicetree describing the board's peripherals and their connections.
