Get Diymore to make STM32 based boards

Post by aroldorosenberg » Sat Oct 27, 2018 5:46 pm

I think plenty of people here have found/bought/experimented with Diymore's "strong" boards (it's what is written on the silkscreen in every one of them). So far they come in ESP8266, Arduino Uno (atmega328 + 16u4), Leonardo (atmega 32u4) and Mega flavors.

Wouldn't it be great if they also made STM32-based board using the same format? They probably browse this board or someone in here knows someone over there, and since they have access to the machinery they could easily have something made and sold over aliexpress in a very small time frame

For those who are not familiar with the boards, they look like this

They already sell a Blue Pill, so a change in form factor is unlikely, IMO.

And why would that stop them from putting the same chip in a more convenient form factor? They also have arduino uno-shaped boards for the Atmega328, I really don't see how selling a bluepill would stop them from selling a different product

Seriously?

If you look closely at the image I embeded, you will note that the board is likely sourced directly from the same Chinese manufacturer that sells to other Chinese distributors. It fills a niche in their products portfolio. Selling another STMF1XX would involve sourcing an already manufactured board or contracting to have one built. Or, maybe they have their own pick-n-place like Adafruit has.

Considering the last maybe, operating a pick-n-place machine for a new product requires some serious work; designing a board, producing the board, manually assembling and testing the board, rework, ordering the boards for a production run, sourcing and ordering the bulk parts, scheduling the production run, testing, loading the optional bootloader, warehousing the hardware , advertising, and selling, shipping.

All the same time, a percent of the new product sales impacts sales of the original product... worst case is that the new product sells well but the old product (with better acquisition to sale profits) ceases to sale. The run-up investment for the newly produced board may not be recovered if sales are not brisk. Results? Lost profits.

Anyone wanting a few boards in the form factor you suggested, could have a few boards produced and using hot-air can transplant the uC from a cheap blue board to the new board.

But to be rudely honest, there is no way in hell that I would produce a new F1xx board: maybe an F4 or 32L series. The F1xx is simply too old of an architecture.

They likely outsource the production to some other huge chinese company like JLPCB and since they're in Shenzhen, it's not that difficult for them. There's a 3d printer motherboard that took less than 4 months to be available for sale completely assembled since the first screenshots of the board were circulating on Facebook, with a lot of components still outside of the PCB and none of the traces actually routed. A simple board like a "bluepill" would take 1 month tops to be designed and manufactured for a pilot run, and it would definitely sell. If people kept putting barriers like that we'd likely never even have the bluepills to experiment with in first place.

Go read this thread: viewtopic.php?f=3&t=4058

The take away for me was.

o People have become addicted to $2 arm boards
o Getting a manufacturer to do anything would take at least 1000 potential buys.

Maybe you should start by polling users to see if this is something that people even want and are willing to buy. If it is only you and a handful of people, you should design the board, build it and split the cost between the people who think it is a good idea.

There was also an effort to get an stm32duino community developed board manufactured. It also went no where:
