Aside from the totally made-up adhoc bs pin labeling (that tripped me up at 3 am in the morning) here are the real problems:
1- After install the Sparkfun board files in Arduino Board Manager - both v1.00 and v1.01, fails to retrieve the ESP32 toolchain. I was able to get things running in PlatformIO. Apparently it pulls a git tag that doesn't exist.
2 - I bought this for data logging. Currently implementations fail to provide sufficient speed with Atmel and most people have switched to STM32's. I have plenty of boards that have SPI bus to SD cards, but nothing that supports the SDIO high speed 4-lane SDMMC interface. Since this is ONLY a data logging board, I would expect it to support this, alas it does not as you have pulled DAT1 / DAT2. I could probably use the ATP carrier and wire up my own SD card, but why then have this product?<p>Very disappointed. I stopped buying from several companies due to this craziness, I guess that only leave that one Chinese company.</p></p>

The DAT1 and DAT2 lines were removed to have a pure SPI interface to the SD card (as opposed to the original SDIO).<blockquote>
<p>Also, what is COPI ?</p>
</blockquote><p>COPI = Controller out Peripheral In. It's part of the SPI bus (along with CIPO, SCK, and CS).</p><blockquote>
<p>Why do I need to come up with a new password and account? Maybe you offer technical assistance to people that don't buy your stuff?</p>

Also, what is COPI ? Also, I used to be able to log into your technical assistance. Did you change it yet again. Why do I need to come up with a new password and account? Maybe you offer technical assistance to people that don't buy your stuff? Kinda makes me feel unloved.</p>

Makes it impossible to design a decent enclosure for any product with this flaw.</p>

As there is no jumper pad to disable the voltage divider (yet), it'll be necessary to break out an X-acto knife to cut the trace or a hot air rework station to desolder the SMD resistor(s) to reduce the quiescent draw.</p></p>
