[College Project] Portable telemetry tracker board

[normal bear]

Hi everyone, im making a portable ESP32 based GPS (SAM-M10Q)/magnetometer(LIS2MDL) tracker with a microSD and an optional external display. The board is powered by a 3.7v LiPo using the MP2667 charging IC and charged with USB-C. This whole design was done pretty quickly as im on a time crunch for the term. Im primarily worried about the battery circuit in the top left of the board and the GPS module in the bottom left. I tried following the layout guidelines as closely as I could. If you would like higher resolution photos or something zoomed in please let me know. Any help is highly appreciated!

Nothing obvious to be but really need to sleep and check it again. Umm, good note for the uart rt-> rx and vis versa

For the pull up resistors connected to J4, it is easier to read vertical text.

SD card might be a little hard to access given how far into the board it is.

If you are unsure about JST polarity, I would have a way on the board to swap them, and some kind of reverse polarity protection

That’s a good idea, I’ll look into it. Thanks!

I’ve messed it up so many times at this point haha
