The hardware is ready!

The two boards are connected using some cables and connectors I took out of an old PC.

Not yet with the 1-Wire bus (just a pull-up resistor to VCC).

Important: the ENC28J60 runs on 3.3V and the JY-MCU must be set to run on the same voltage (as you can see on the bottom left corner).

The connection use the standard SPI wires/pins (see previous post), reset signal and power (VCC, GND).

Next stop: web server software!

And the schematic:

IMPORTANT!

The 3.3V regulator on the JY-MCU is too small to power up the entire system.

See Power failure of the 3.3V LDO and Back on-line with home made power regulator

Note for DS18B20: The device VDD pin must be grounded for operation in parasite power mode.
