Just worried about noise pick up.
The the components are maily resistors are mainly resistors that carry a PWM signal (low freq) for driving a MOSFET, some decoupling caps in the VBAT, 3V3, 1V8 and VDAC pins and two resistors connected in series with the UART0 pins.
No space issue here since all packages are SMD0805 and SMD1206.
I see in the balenaFin there are decoupling caps underneath the CM3 module.
Thanks for your input!
