Ethernet JIG for Nucleo H743ZI2
Details
This is a LAN9220 ehternet controller board for the Nucleo H743ZI.
The LAN9220 is accessible through the FMC SRAM configuration NE1. The LAN9220 doesn't have READY signal. Thus, the wait cycles should be set by program appropriately.
The following signals could be assigned to the interrupt (EXTI).
- PME : PA0
- IRQ : PA4
Nucleo Pin configurations
The followings are the pin configuration of Nucleo board.
Also, short bridge have to be configured as the followings :
- PD8 : Cut SB12 to disconnect the STLINK VCOMM signal.
- PD9 : Cut SB19 to disconnect the STLINK VCOMM signal.
- PB6 : Short SB9 to assign LPUART1_TX to STLINK VCOMM signal.
- PB7 : Short SB34 to assign LPUART1_TX to STLINK VCOMM signal.
The USART3 is connected to STLINK VCOMM through the PD8 and PD9 by default. These pins are re-assigned to FMC. Thus, the LPUART1 have to be connected to the STLINK VCOMM through the PB6 and PB7.
PD6 (FMC_NWAIT) and FMC_NE1 (PC7) are not used in this board.

Questions
How big is the Akashi-13 PCB?
It measures 67.3 × 91.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Akashi-13 use?
38 parts, built around the LAN9220-ABZJ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Akashi-13 KiCad files?
From the suikan4github/Akashi-13 repository on GitHub, at the commit this page was made from: the board is Akashi-13.kicad_pcb and its schematic Akashi-13.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Akashi-13 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
