Overview

Epc2361-prototype is an open-source printed circuit board by EnesAyaz, from the EnesAyaz/KTH repository on GitHub. It is a 4-layer board of 76 × 53 mm with 44 parts on 19 nets, routed with 550 tracks and 109 vias.

It is built around the LMG1210RVR, EPC2361 and BAS21H. Its parts include 18 capacitors, 1 IC and 1 diode.

SPB building block: KiCad placement

PLACEMENT ONLY. NOT NETTED, NOT ROUTED. DO NOT FABRICATE.

30 x 28.2 mm, 4 layers (2 oz), 2 x EPC2361 per switch in two mirrored cells, centre gate driver (LT8418), 24 x 10 uF 1210 bank + 12 x 1 uF 0805 local MLCCs, split gate resistors (0402), probe pads, busbar contact pads (DC+, DC- top; AC bottom).

The board is generated from the same geometry as the Q3D and Icepak models (simulation/bb_q3d/bb_geometry.py): copper of all four layers is drawn as the graphic shapes used in Q3D (L1 strips and cell islands, L2 DC-, L3 DC+, L4 AC) with the via rows.

KiCad 7 cannot export VRML without its GUI, so the renders are drawn by render_board.py from the board data and the KiCad VRML models. In the KiCad GUI, View > 3D Viewer shows the same board.

Questions

How big is the Epc2361-prototype PCB?

It measures 76 × 53 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Epc2361-prototype use?

44 parts, built around the LMG1210RVR, EPC2361 and BAS21H. 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 Epc2361-prototype KiCad files?

From the EnesAyaz/KTH repository on GitHub, at the commit this page was made from: the board is PCB-Design/hardware/epc2361-prototype-p3/reference-p2/epc2361-prototype.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Epc2361-prototype design in my own project?

Its repository states no licence, so its author keeps all rights: ask EnesAyaz before reusing the design.
