Project description
Air105 itself does not support Ethernet, but can use W5500 as a full hardware Ethernet stack. Occupies SPI2 (4 pins) by default: Air105 pin Function PB4/GPIO20 SPI2_MOSI PB3/GPIO19 SPI2_CSN PB2/GPIO18 SPI2_CLK PB5/GPIO21 SPI2_MISO Note: W5500 has extremely high requirements on power supply and needs to support a large instantaneous current. Unstable power supply will lead to unstable operation of Air105.
