I have a black pill, but board is green in color, chip says stm32f401ccu6, 44pin.where can i get a pinout diagram for this board, ?only blackpill boards pinouts that I can see are the newer 40 pin boards
Hi,I have been trying to design a double stage single phase grid connected PV Microinverter system.I came across an Application Note AN4070, in which you have designed a 250W grid connected Microinverter. I tried to follow the procedure and design an...
Hello,I'm working on a project that requires the implementation of NB-IoT and to do this I started by testing the Discovery Kit B-L462CELL1, which is very poorly documented. I also noticed that the LBADXX1SC modem used by the kit is now obsolete.Can ...
Hi,I am doing the evaluation of ST33KTPM2X-i2c on my Linux v6.1.70 embedded system.According to the 'Enabling TPM support in the Linux kernel from the version 6.1' from an5714-integrating-the-stsafetpm-trusted-platform-modules-with-linux-stmicroelect...
Hello.I want to use STUW81300 to create 9 GHz with great phase noise.Reference: 50 MHzPDF:50MHzSingle-EndedSTWPLSim v5.3 was used for the loop filter design.However, the actual measurements were 3~7dB worse than the simulated values.All settings see...
Both STuW81300 and STW81200 have the option of using an external VCO but the inputs characteristics aren't specified anywhere. What is the input frequency range, input power/sensitivity in dBm or 50ohm match for single-ended input? There is one appli...
Hello,According to data sheet on STuW81300 the ST1.PLL_SEL must be 1 and Nint, Frac must be calculated based on formula on page 25, when VCO frequency if higher than 6GHz. In this case the sub-harmonic at half frequency appears. How could be this sub...
Hello,When the ST1.PLL_SEL is set to 1 for VCO Frequency > 6 GHz, the sub-harmonic at half frequency appears. How could it be eliminated? Thanks,Alex
Dear forumI need to update a board that uses BMO055 9 axis IMU and I need to know what is the preferred ST solution that best fit this obsoleted part.I need the 3 axis gyro + 3axis accelerometer + 3 axis magnetometerIf there is a single chip solution...
