It would be better just to do the natural pinout and then fix the templates, rather than doing more complex than necessary routing and then locking that in for future runs. It would also make sense to update all the CoBs to 4 layer for better signal integrity if the cost difference is negligible.\nThat does obviously require the generic CoBs are completed reasonably quickly so that the template can be updated in plenty of time for the run 2 designs. But I wouldn't suggest moving any of the power pads, clock or reset, and beyond that it is likely that pinout matching only matters if people are submitting the same design at different slot sizes, or expecting a common motherboard to work between different slot sizes on the basis of using pins with the same name in the template.\nThoughts?", "author": { "id": "691780627338625077", "name": "rebelmike", "discriminator": "0000", "nickname": "RebelMike", "color": null, "isBot": false, "roles": [], "avatarUrl": "2026-05_media/49aaff687e56f04e7bbdedf0077bab75-7DDB4.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [], "inlineEmojis": [] }, { "id": "1507137958451613898", "type": "Reply", "timestamp": "2026-05-21T21:48:10.564+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "I've been speaking with @Tim 'mithro' Ansell and have been wanting to change things about the layout and the standard template and fix things at the beginning so it's harmonized across the sizes from the start.", "author": { "id": "756011607603019777", "name": "anfroholic", "discriminator": "0000", "nickname": "Andrew Wingate", "color": null, "isBot": false, "roles": [ { "id": "1423020172595298314", "name": "Mod", "color": null, "position": 1 } ], "avatarUrl": "2026-05_media/67bd670a335a2f955fb2ded57088a2cb-675B3.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [ { "id": "169786952432746498", "name": "mithro_", "discriminator": "0000", "nickname": "Tim 'mithro' Ansell", "color": null, "isBot": false, "roles": [], "avatarUrl": "2026-05_media/9679bb77da48d47c905b398d98a83780-75B68.png" }, { "id": "691780627338625077", "name": "rebelmike", "discriminator": "0000", "nickname": "RebelMike", "color": null, "isBot": false, "roles": [], "avatarUrl": "2026-05_media/49aaff687e56f04e7bbdedf0077bab75-7DDB4.png" } ], "reference": { "messageId": "1507137474617413652", "channelId": "1408134567491145728", "guildId": "1361349522684510449" }, "inlineEmojis": [] }, { "id": "1507138895450472458", "type": "Default", "timestamp": "2026-05-21T21:51:53.962+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "Cool, it probably wouldn't take long to work out what the natural pad order would be and adjust the default template, even if the routing isn't actually done at that point.

What are your plans with regards to matching the pinout?\nIf we want to keep that many pins on all the half slots and drop 2 from the 1x1 we end up with them all being identical. I don't know what this means in reality, but if someone wanted to prototype on a half slot, then move to a larger size, the pin/padout stays identical. \n\n> PS: Looking at the CoB PCB for the 1x1 slot, pin 1 of the mezzanine connector seems to be in the top right corner rather than the top left. Why is that the case?\nKiCads generic connector library and most packages and connectors in general have pin1 in the top left. I would prefer, if someone were to take a generic mezzanine connector and use the footprint provided by the manufacturer, for pin1 to line up.
