STM32WL55JC RF Power Measurement
I'm currently testing a board that I designed incorporating an STM32WLJC55. The RF section is based on the 433 MHz MB1389E reference, with component changes due to availability issues and some PCB layout revisions. The design does successfully trans...
BLE_TransparentMode with STM32WBA52CG
Hello,after some issues I was able to communicate with EvalBoard MB1801D and MB1803B (STM32WBA55CG) and the STM32CubeMonitor-RF Tool Version (2.18.0) .In the first step, I wanted to use the RF board MB1863 (STM32WBA52CG) in conjunction with the MB180...
UFBGA Paste Stencil Recommendation
Hello, I'd like to use the STM32WLE5 in an upcoming design. Looking at the datasheet, I noticed the recommendation for the BGA package is to have the stencil opening larger than the pad diameter, instead matching the ball diameter . To me this seem...
