Ulx3s
Ulx3s is an open source ESP32 PCB design by emard: a 4-layer, 94 × 50.8 mm board with 212 components (64 distinct parts). It is built around the LFE5U-85F-6BG381C, MT48LC16M16A2TG-6A, TLV62569DBVR, FT231XS and more. Filed under iot & wireless and usb & debug tools and rf & radio.
PCB for ULX3S FPGA R&D board
ULX3S = University digital Logic Learning Xtensible board release 3 with SDRAM, Successor of ULX2S.

Prototypes available at SKRIPTARNICA, local shop inside of FER university.
This is a small (94x51 mm) standalone FPGA board for education, research and general purpose, with a full featured selection of chips which I all wanted on a low-cost PCB, but haven't found on the market. It's open source and open hardware because if it is good for our development of f32c SOC, it should be also good to other projects.
