Scope Addin Board Project
This is an addon board for my 54831B Infiniium Oscillioscope. It includes an ethernet switch (RTL8367S-CG), HDMI to Parallel converter, and VNA module for S-parameter analysis. It is controlled using a STM32F407 microcontroller, with external CAN and Ethernet busses for communication with any future oscilloscope devices I design.

Ethernet Switch
This board has 3 external gigabit RJ45 connectors, and 2 internal connectors.

Power Supplies
The board is powered using a standard ATX-20 pin plug, controlled by the STM32 on standby power. There are six power rails for the peripherals, and each one contains a power switch as well for control by the MCU. Each power rail is current limited and has its own fuse to prevent damage to the device.
