Ah, I thought they were 3.5mm. I looked at using 2.54mm but couldn't get even the smallest ferrule in the samples I got so moved up to 3.5mm. Even those are pretty tight with ferrules. I agree about pluggable...
Nice job! Based on the thread, I think you soldered the micromod connector by hand, right?
If you make any changes to the carrier board, a few suggestions.
- Support Trinamic based Step Sticks. add the two extra...
I see no evidence of stupid questions... In fact, your servo questions are insightful.
There may be a servo error input added to grblHAL in the future though there are plenty of ways to handle it now - 2 of which...
This sensor is very sensitive to the pull-up value. You should probably start there. I had one that never did work with a T4.0 but would with a T2.0. I later managed to kill the sensor and the replacement worked...
Well, for free is a bit of a come-on. There will be engineering fees, a lot of parts have a min order count and smaller SMD parts have "attrition" (think of it as the number of parts wasted loading the tape on their...
JLCPCB has ESP-07s and ESP-12S in their library and, surprise, in stock. They also have a bunch of Espressif modules (and in stock, too!). This looks to be a fairly recent addition. We'll see how well they maintain...
Not wanting to push the Chinese disti LCSC.com but they have ESP-01, ESP-07, ESP-07S, ESP-12E, ESP-12F for good prices and volume discounts. You can get them via DHL or UPS for quick delivery - typically 5ish days to...
grblHAL is an open source motion control system for CNC machines like mills, router, lathes, laser cutters and anything that uses stepper motors or servos. It is the 32-bit version of Grbl that originally ran on 8-bit...

They do 5 mil traces and .2/.45 vias. I've used them quite a bit for both 2L and 4L boards.
If you can use them, their 4L boards are much...
I am measuring the max rate that a stepper motor is driven at. Because steppers require acceleration and deceleration for best performance, the train of pulses does not have a fixed period. It was getting tedious to...
Well, all the controllers on that list are based on the old 8-bit Arduino design and only support 3 Axes. Also, a lot of them don't have any isolation or noise control so EMI can cause problems like controller reset...
As long as you are looking at headers, It would be great to find 2x3 2mm header+socket for the teensy 4.1 that works with the the 2.54mm pitch sockets. I've had real trouble finding ones that work together. The 2mm...
OK, that was good for a laugh. Over at EEVBlog there are several long threads about the Blue Pill Problem including some decapped STM32F103 showing that they weren't made by STMicro. I think they identified something...
FedEX says delivery on Tuesday 11/24. However, I have another package (unrelated) that arrived at Memphis within 20 minutes (probably on the same plane) of the Boards and they are saying that will be delivered on...
Amen to that. That's one of the reasons I based my CNC board on the T41. Another is that, unlike the BluePills and such out there, it is a totally consistent package. If you buy a BluePill today, you probably won't...
Welcome! It's good to have another WA company building on Teensys.
Looked at your store and see at least one Unicorn - reasonably priced 1x24 pin sockets! I usually just cut down 1x40s and hide the ugly end.
I am out of stock right now but have a batch arriving in the next couple of days. And another batch is coming after that. Demand has been increasing and the Hackaday article was a bit of a tidal wave but I am committed...
