@Abse @0hmx @Seve please review:

Try to use a `schematicsheet`/`schematiSection` to make the schematic readable

done

<@778624824875941908> if you are ordering the board lmk to i will order mine too

i would order just want a review from <@757706909351411845>

We need a pedometer, anything else im not paying attention to

Not today anyway

They said specifically in the vid they needed different ti chips integrated together

Anyway maybe it is good to have

Btw the top bottom board margins make it difficult to use with a bradboard

it looks like a nice board (other than the margins) but i don't think it creates the demo they're looking for rn

i think if you adjust the margins so it can fit into a breadboard you should try to order today

it is a good backup if all the pedometers fail

i'm surprised at that change lol

the pinheaders need to be very close to the edge of the board so they don't block the wires that you put in adjacent to them

i should have sent a pic

do you see how the board edge makes it difficult to insert a breadboard wire without bending it? In fact the width in general makes it a bit hard to wire tbh

your thin version is much better in this way

but i don't think it needs to be that long

oh, i see

<@757706909351411845> this is not what i intended but look what i got 😂

Wild

<@757706909351411845> i have put too many components that it would have to be very long for this specific width

haha idk man

that board is super empty

but also i didn't say to change your width rofl

self-imposed

it needs to be a specific width to fit into the breadboard right?

it needs to match pico but my point has always been about the margin beyond the pinheaders

pico is your standard

and i never mentioned shrinking the width etc.

(never mentioned shrinking below pico)

lgtm ship it

it's not programmable i think- is there a programming jumper....

what is the programming jumper?

we just discussed in voice but 99% of the time you can't program over USB

especially because you're using a chip to facilitate USB

you have to break out SWD (SoftWare Debug) in a JST to program 99% of chips

you can also just ask ai "how do i program this" and if it suggests connecting to pin headers you know you messed up b/c then i have to solder 😁

the agent did tell me it's programmable with usb, here's it's response to your concern: The reviewer raised a reasonable question, but his conclusion—“it’s not programmable”—is incorrect for this MCU and board. TI explicitly documents that the MSPM0G3507: - Ships with its ROM bootstrap loader enabled. - Can program flash over UART. - Uses PA10 as default BSL TX and PA11 as default BSL RX. - Uses PA18 as an active-high BSL-invoke input. - Enters BSL automatically when blank. MSPM0G3507 datasheet Our board connects exactly those signals: - CH340 TX → PA11/BSL RX - PA10/BSL TX → CH340 RX - BOOT button → PA18 high - RESET button → NRST low - PA18 has a normal-state pulldown TI’s own programming documentation describes using PC software with a USB-to-UART bridge, so the reviewer’s statement that the bridge makes USB programming unlikely is backwards—the bridge is what enables it. TI BSL implementation guide What is valid in his feedback: - This is not native USB or Pico-style UF2. - The CH340 cannot automatically toggle BOOT and RESET in this design; you must use the buttons manually. - A dedicated keyed SWD connector would make debugging and recovery more convenient. - The board exposes SWDIO, SWCLK, RESET, 3V3 and GND on the headers, but not as one convenient JST/Tag-Connect socket. - USB BSL must be tested on the first physical board with the selected TI host software. If firmware later disables BSL or enables incompatible fast-boot settings, SWD becomes the recovery method. So: no programming jumper is required. The BOOT button performs that function. His SWD suggestion is a reasonable convenience recommendation, but SWD—and specifically a JST connector—is not required to initially program this board over USB-C.

ok deal

let's order

actually

you should break out SWD lol

because of what the AI is saying, we won't be able to automatically reboot and reload etc.

which is a very nice feature with ai

ok

i ordered after you said let's order, and you can't cancel

ha ok

you can cancel but wtvr it's fine
