Hi, im in the process of designing a stm32H7 board, i chose the only h7 that was available from jlcpcb at the time (STM32H743VIT6) , was a couple of weaks ago, might have changed now…
The problem is that the STM32H743VIT6 in lqfp100 package is a bit to big for the standard micromod outline, so i decided to make it a bit larger, i will mostly use this with my own carrier board. but could there be any problems with this “enlargement” ?
Don’t see any reasons off the bat that would cause any issues, you just need to make sure there are no tall components on the carrier board that would get in the way.
For example, the [MicroMod Machine Learning Carrier Board has a SD socket to the left of the processor module socket and I believe it’s short enough for a processor board to clear it but if the SD socket was taller, you’d definitely have issues.](SparkFun MicroMod Machine Learning Carrier Board - DEV-16400 - SparkFun Electronics)
thx!
Tbh i just wish some BGA wizards would step in and create a stm32h7 board without any size changes to the micromod, but well see… maybe i should try
