Can we introduce thermalPadNotchLeft and thermalPadNotchRight for these types of thermal pads?

## Seve — 2026-08-21T06:05:26.629000+00:00

ehh

## Seve — 2026-08-21T06:05:32.374000+00:00

you would need to show it's more universal

## Seve — 2026-08-21T06:05:38.192000+00:00

i don't know if this is common

## Seve — 2026-08-21T06:05:43.433000+00:00

if it's in IPC then we could

## techmannih — 2026-08-21T06:07:31.123000+00:00

yeah, makes sense. gotcha

## techmannih — 2026-08-21T21:16:48.344000+00:00

<@757706909351411845> It seems too expensive and is also out of stock i think

You should have looked this up before you started working on it

## Seve — 2026-08-21T21:17:27.565000+00:00

Yes we cant order it

## techmannih — 2026-08-21T21:17:39.966000+00:00

I think we can switch to this module if TI doesn’t show much interest in it.

## techmannih — 2026-08-21T21:20:02.159000+00:00

Right, but why do we have to check this manually every time? I think if a chip is out of stock, we shouldn't be able to import it in tscircuit??

## Seve — 2026-08-21T21:20:37.928000+00:00

You could throw a warning on jlcpcb import but not an error

## Seve — 2026-08-21T21:20:52.864000+00:00

*tsci import

## techmannih — 2026-08-21T21:21:07.662000+00:00

yea sg

## techmannih — 2026-08-26T00:57:19.506000+00:00

<@757706909351411845> I'm planning to build the Allwinner T113-S4-based Trellis Core. Is that okay?

Board reference:
https://github.com/protolux-electronics/trellis_core

## Seve — 2026-08-26T01:27:53.482000+00:00

sure just get it done quickly because it looks fairly easy! Try to break out a SPI bus via a JST connector so that i can connect a display to it!

## Seve — 2026-08-26T01:28:38.828000+00:00

how do you program this?

## techmannih — 2026-08-26T01:39:05.649000+00:00

The T113-S4 has a built-in FEL boot mode. We can put the board into FEL mode using the FEL button and connect it to a computer via USB-C. Then we can use `sunxi-fel` on the computer to load the bootloader/system image, 

Hold the FEL button → Connect the board to the Mac via USB-C → T113-S4 is detected in FEL mode → Run `sunxi-fel` commands on the Mac → Load the bootloader/image.

## Seve — 2026-08-26T01:46:23.481000+00:00

FEL button?

## techmannih — 2026-08-26T01:48:14.019000+00:00

yea I mean the UBOOT button on the Trellis Core. It is used to force the T113-S4 into FEL/USB boot mode

## Seve — 2026-08-26T02:02:31.453000+00:00

there is no UBOOT button from the screenshot i see

Ohh dam AI f''*k me, sorry the PCB doesn't show a button labeled FEL. The repo only states that the schematic includes Reset and FEL mode buttons, while the PCB render shows them as SW1/SW2.
