My new PYB Nano board is coming

[OutoftheBOTS_]

I am on Sunshine Coast just north of Brisbane.

The Ardunio community is also building a small form factor STM32F405 board in same form factor as the famous blue Pill (stm32f103c8t6) here is a pic of it https://ibb.co/m512be. They have https://robotdyn.com/ to manufacture it for them but they r wanting a very noise free ADC so r still in the testing stage of the ADC and I am not sure when/if it will ever be available. They are aiming for $10US plus postage price range.

A STM32F405 offers a lot more then the STM32f103 but all the cheap STM32F405 boards don't have the same form factor. I have a STM32F407VET that I prototype on but it is a very big for a robot control board.

I am keen to get one of the nano's on this thread if the postage isn't a killer on the price.

I have also made a STM32F405 board, it is bigger then pyb nano.

And I plan to design a new board, with very small size and lower cost, no onboard SD socket, no accelerometer.

I am really interested in the super small form factor STM32F405RG. On Aliexpress you can buy a much larger very fully featured STMF407VET for under $10US see https://www.aliexpress.com/wholesale?ca ... 32f407vet6

Maybe you should check out the design the Ardunio guys have been working on as they have designed a STM3232F405RG board same size and pin compatible as a blue-pill with a SD card slot on the bottom of the board and then 4 solder pads for the remaining pins that didn't fit on the bread board breakout being pin compatible with blue pill. see the super long thread http://www.stm32duino.com/viewtopic.php?f=19&t=2633

I would like to buy a few of these, but taobao is a show-stopper for me.

Why not put it on tindie, or ebay or some place that is more accessible to those of us not located in China.

It is not easy for me to ship outside China, is somebody can help?
