Description The code is a slight extension of the original WebServer.ino (https://github.com/arduino-libraries/Ethernet/blob/master/examples/WebServer/WebServer.ino) sketch with the addition of reading out the supply voltage of the board. No changes to the Ethernet library have bene made. Wireup Refer module datasheet for details. Power pins: All GNDs to Bluepill's GNDs, all VIN3.3 pins to Bluepill's 3.3V since the module is power-hungry, extra decoupling capacitors on the 3.3V rail are recommended SPI: use default SPI1 (SCK = PA5, MISO = PA6, MOSI = PA7) and arbitrary chip select (here CS =…
