Hey guys,
I am looking into using the teensy (specifically the 4.1) ecosystem on a wearable application to achieve low latency high frequency data logging of various sensors (motion, environmental...). I was wondering if there is any open source design of "the smallest" form factor Teensy 4.1 with ideally an SD card slot (connected over SDIO). I found the micromod from sparkfun open source which can be a good starting point for a customized board...
The reason I am asking is that I have done custom ESP32 boards in the past but never a complex MCU with BGA pads even more so. Therefore, I am not particularly aware of the critical considerations for designing a board and routing signals for such a dense mcu.
Any tips or recommendations are welcome.
Thanks in advance !
