Work in Progress – managed to finish schematics and place components – a bit more than I expected, but extended board on right side with 2cm so it goes wall-to wall in the box and SD-Card comes out as awell. Using KSZ8863RLL to achieve dual Ethernet on this. The MCU will see this as a RMII interface and it will act as a switch. This is a first draft as I have to go through the schematics again and document each component and optimize the layout a bit. But, it looks good. I use 2 x single RJ45’s so I can decide to populate with either none, one or two Ethernet on the same board. RJ45’s, SD Card and USB is not really waterproof “as is”, so might need to do something on the lid side on these.
- 1 x STM32H723Vx – 512Kb Flash, 560Kb SRAM ticking at 500Mhz.
- SWD Connector
- 1 x USB
- 1 x CANFD
- 2 x 10/100Mbps Ethernet
- 10 x Module connectors
- 1 x SPI Flash
- 4 leds
This board is still a bit work.
