production ready STM32 boards

Hi,Does anyone know if there are any companies out there that sell production ready stm32 hardware boards. I appreciated there would be a lot of variations regarding io etc.. but i just wondered if it was a "thing" or if the only board are typically ...

I am working on STM32H743 micro operating as a slave I2C device. I am able to write to the slave device by a master I2C device but I can't seem to read.

I have done some investigation and arrived that the problem is with the "DIR" bit in the Interrupt Status register not firing to indicate whether to do a Read.uint32_t isr_trace[64]; int isr_count = 0;   void I2C2_EV_IRQHandler(void) { isr_trace[...

[How to] From Mechanical to Capacitive controls Guide (Buttons with sharp edges and 2mm clearance, 2 layer pcb with cover glass (50x70mm))

Even though most of you may be relatively familiar with the various types of mechanical controls, the same does not necessarily apply for capacitive ones. So, let’s start off by defining the most basic elements of capacitive sensing.Capacitive button...
