From 5129a5a5448012a53cb9ddae1349c2a2c8571339 Mon Sep 17 00:00:00 2001 From: Friedrich Beckmann Date: Sun, 8 Nov 2026 18:14:54 +0100 Subject: Add KiCad 9 schematic, project libraries and datasheets Schematic (kicad/), one sheet per function as on ULX3S: - power: TLV62569 bucks for +1V1 / +3V3, AP2112K LDO for +2V5 - usb: USB-C with PTC and TVS, CH347F for JTAG and UART - fpga_power, fpga_config, fpga_banks_01/23/67: ECP5 LFE5U-25F caBGA256 (pin compatible with the 45F), quad SPI flash, 50 MHz CLOCK_50, ball assignment as in PINPLAN.md - ethernet: RTL8211F gigabit PHY, HR911130A RJ45, shield via 1M || 1nF 2kV - sdram: 32 MB W9825G6KH-6 - hdmi: TMDS from the FPGA (LVCMOS33D), AC coupled, ESD protected - user_io: SW, KEY (debounced), LEDR, LEDG, HEX0-HEX3 with DE1 names - gpio: two DE1 compatible 2x20 headers (THDB-ADA on GPIO_0), Pmod A/B, ESD arrays - testpoints: bring-up pads, M3 mounting holes All parts have LCSC numbers, MPN and manufacturer for JLCPCB assembly; footprints are cross-checked against the EasyEDA data. Libraries: ECP5 symbols generated from the Lattice pinout CSVs (kipart), CH347F, RTL8211F, SM410561N symbols, HR911130A symbol and footprint from KiCad library merge requests, generator scripts in lib/tools/.
