Re: Greetings from Cyprus/Sunderland

Steve, I think that this forum is not the proper place to do transactions between individual forum members. I gave you a description of the problem I have seen in past and missing solution for small STM32 boards. I have limited interest in creating a solution for this specific problem. My preference...

Re: Greetings from Cyprus/Sunderland

Steve,

Thanks for considering this idea. I have not done any SMD work and would prefer to purchase assembled boards.

Re: Greetings from Cyprus/Sunderland

Steve, In this picture https://github.com/OliviliK/STM32F103/blob/master/BLOB/Images/Blue%20Pill%20with%20terminations.png?raw=true you have the original Blue Pill above. Below that, you have the modified Blue Pill with female pins for the original signals in the blue rows. Next to that at 0.1"...

Re: STM32F746 Arduino Board

My observations and comments are that for the Arduino Uno environment, the users need to have higher performance and pin compatibility for existing shields and for Arduino Mega environment the existing shields are not a limiting factor. The existing shields do require +5V compatibility, which is an ...

Re: Advice sought regarding mesh networking devices

Steve, I do share very much the comments by Roger. I was following very closely the development of Honeywell One Wireless mesh and can confirm that it was a quite large undertaking over 10 years ago. Now we have new technology available and it can be done with a lower effort. I am planning to do it ...

Re: Greetings from Cyprus/Sunderland

Steve, Thanks for the additional info. In applications with large number of sensors and servos, a significant challenge is to arrange the common ground and supply voltage for those 3 wire connections. A normal breadboard is not very good on that due to extra cap between signal and common lines, extr...

Re: Greetings from Cyprus/Sunderland

Efftek, What kind of wiring technology you are using for the sensors connected to your ADC boards? For Arduino Mega, I have found a nice sensor shield at Aliexpress for 3 wire Dupont connections for AI, DI, and DO signals. I have been looking a similar solution for blue pill and similar smaller boar...

Re: Taobao stm32f103Rrft6 board.

Victor,

I am curious if you have been using multiple agents in dealing with Taobao. Do you have any recommendations for quality and cost of service among them?

Recommendations for distributed system

I have a collection of different ESP32 boards and an intention for a high speed wireless communication between them. I would like to hear recommendations from the forum readers for the "best practices". The use cases are: 1) Put ESP32 inside a game-pad to drive a robot controlled by ESP32 ...

Re: GreenPill board specification

We should follow the Teensy model, where the "low cost" 3.2 is compatible with the "high performance" 3.5/3.6 boards. In other words, do a very compact and low cost F103 color pill so that a pin compatible F4xx color pill can be designed for more pins, higher functionality and hi...
