Frequently asked questions
Which microcontrollers can drive it?
Any board with a free SPI bus and a spare GPIO for chip select can drive it, provided a driver library for CH390H is available. W5500 libraries are not automatically compatible, so confirm driver support first.
What wiring does it need?
Connect the SPI lines (MOSI, MISO, SCK), the chip select line, power and ground. Confirm the supply voltage and pin labels in the module's documentation before connecting.
