S2LP SMPS1 VOLTAGE PROBLEM
Hello;My Name is FATIHI am using Wireless MBUS water meter scanning using S2LP and STM32L073. While making the PCB design, we applied the reference design value in the x-nucleo-s2868a2_schematic.pdf file exactly. However, although we see VDD voltage ...
STKNX circuit, high power loss at single fault condition: CFH (capacitor) shorted.
We based our circuit on the "STKNX Reference Design" (V1.0, 14. Nov. 2019)).In the case of the single fault condition of a shorted CFH capacitor during operation almost the whole KNX bus voltage (21-30V) is permanently over the 68R resistor (RTX) and...

BlueNRG M2SA - same pins, different functions
Hello,Looking at the documentation of the M2SA module, I noticed that the function of the same pins (21, 22, and 23) differs between the datasheet and the application note. Does anyone know the exact function of these pins? M2SA - application noteM2S...
LIS2DU12 reset / drdy interrupt
Hi,I am working on the LIS2DU12, but unfortunately it does not yet work as I expected. I do a reset and wait with the status bit of reset until it is done. The system is therefore in power-down. I then set the drdy. This immediately triggers the int...
