Hello,I am searching for the input/output impedances for my STM32L476RG microcontroller and I can't find any information in the microcontroller datasheet or else where on the web. Are those values given in any documentation? If not, can they be calcu...
STM32 Discovery boards NRNDed
ST marked several Disco boards as NRND (i.e. discontinues them).Some of them are easily replaceable - e.g. the 'F0308 by the 'F0, the 'L100 by the 'L152, the 'F7308 (which btw. is only a few months old) by the probably completely identical (except fo...
