I've worked on OEM ECUs with 400+ pin BGAs, they were underfilled to help prevent vibration issues. You do need to be very careful with the PCB design because any imbalance in the copper that causes the PCB to warp a little will cause big problems. The 33810s are usually very reliable so they must be doing something wrong.

Hi tooly
Can you say if speeduino firmware september 2019 can work with your modification integrate ADS7953 analge inputs via spi ?

hi nicoefi,
i dont think so at the moment. the nanolambda code ist also not integrated/testet with the stm32f407. i also have to check the pwm channels suported in speeduino.

The MCU hast been changed from Teensy 3.5 to STM32F407VGT6.
The whole KiCad project has been uploaded to this repository:
