Does anybody know how to help with this question?
Surely there is a specification from Espressif whether to wash boards after reflow, or to use no-clean solder paste...
Thank you,
Connor

Post Reflow Cleaning Recommendation for ESP-WROOM-32?
Hello,
After re-flow soldering, what does ESP recommend as the cleaning/washing process?
Is it OK to wash this part, or do we need to use no-clean solder paste?
Thanks,
Connor

Re: ESP-WROOM-32 Bootstrapping
1. It's only used in SDIO boot mode, which is a mode where the ESP32 does not boot from external flash but from its SDIO interface; a host machine should send it data. Because there's no firmware running at that moment, the configuration has to be done using bootstrap pins. 2. If the flash voltage ...

ESP-WROOM-32 Bootstrapping
Hello, I've got a few questions relating to the bootstrapping pins on the ESP module. Specifically: 1) What is the purpose of the "timing of SDIO slave" strapping pins? I am guessing that the state of these doesn't really matter as it can also be configured in FW. But how can the flash memory proper...
