# W5100 schematics review

## Question

Asked by tecknorapture on 2016-03-30 in Ethernet Chips.

Hi,

I was wondering if someone can check if I have create this schematic correctly for the W5100. I have based it similar to the WIZ811MJ but I use the ABM7-25.000MHZ-D2Y-T for the 25 MHz oscillator. The SPI interface to STM32 microcontroller.
