lgtm

## Seve — 2026-08-19T18:57:16.587000+00:00

it's wayyy too big tho lol

## Seve — 2026-08-19T18:57:24.856000+00:00

i would shrink it but otherwise yea looks good

## Seve — 2026-08-19T18:57:52.366000+00:00

actually

## Seve — 2026-08-19T18:57:55.949000+00:00

aren't you missing output pins

## Seve — 2026-08-19T18:58:06.093000+00:00

yea this is totally wrong

## Seve — 2026-08-19T18:58:12.515000+00:00

you need A+, A-, B+, B- no?

## Rishabh — 2026-08-19T18:59:27.993000+00:00

Did multiple rounds of review from codex

## Seve — 2026-08-19T19:20:23.706000+00:00

how would you plug in a FOUR WIRE stepper motor

## Seve — 2026-08-19T19:20:30.748000+00:00

oh

## Seve — 2026-08-19T19:20:36.757000+00:00

you use two terminals for a single motor

## Seve — 2026-08-19T19:20:50.225000+00:00

yea your silkscreen is really bad

## Seve — 2026-08-19T19:21:06.658000+00:00

there is no "motor a" and "motor b", there's ONE motor with A+/A- and B+/B-

## Seve — 2026-08-19T19:21:42.617000+00:00

i think it's not clear- usually that would be a single wire terminal, but even then the silkscreen is super confusing A+/A- is COIL A and B+/B- is COIL B of a single motor

## Seve — 2026-08-19T19:22:22.498000+00:00

you also called it a DUAL MOTOR

## Seve — 2026-08-19T19:22:38.451000+00:00

it is not a dual motor driver, it is a single STEPPER motor driver

## Seve — 2026-08-19T19:22:45.475000+00:00

or am i wrong

## Seve — 2026-08-19T19:22:57.806000+00:00

is this a brushed motor driver? I don't think so

## Seve — 2026-08-19T19:23:07.821000+00:00

i'm pretty sure there's a lot of confusion

## Seve — 2026-08-19T19:23:14.204000+00:00

this is a single stepper motor driver

## Seve — 2026-08-19T19:23:19.022000+00:00

and there's a ton of stuff mislabeled

## Seve — 2026-08-19T19:23:26.444000+00:00

it's not a dual motor driver

## Seve — 2026-08-19T19:23:40.137000+00:00

the fact that codex didn't tell you this indicates it's cooked

## Seve — 2026-08-19T19:23:53.022000+00:00

also i would shrink the board a lot tbh

## Rishabh — 2026-08-21T14:43:01.746000+00:00

https://imrishabh18--rp2040-motor-controller-v1-0-10.tscircuit.app/#file=index.circuit.tsx

Have shrunk the size, and the terminal is combined to one 4pin terminal to for nema 17

## Seve — 2026-08-22T00:32:03.304000+00:00

still very wide tbh

## Seve — 2026-08-22T00:32:05.661000+00:00

but looking good

## Seve — 2026-08-22T00:32:15.974000+00:00

one sec will review

## Seve — 2026-08-22T00:40:36.749000+00:00

## Seve — 2026-08-22T00:40:42.292000+00:00

will take a second to upload

## Rishabh — 2026-08-25T13:05:47.126000+00:00

reduced the board size and no more via's on the crystal trace

Looks good!!!
