How to connect a D1 Mini to a PCB?

I'm trying to integrate a D1 mini to a PCB I'm designing, and not sure what the best way to attach it is. I'm trying to keep the PCB as thin as possible so I'd rather not add headers.

Is there some clever way to attach this board to a PCB?

Thanks for any help or suggestions.

Re: ESP IDF installation error: Unexpected end of archive

I think there might be something wrong with the linked version? I tried several times with the current version but it failed every time. When I selected the previous version it worked right away.

Re: Possible to have esptool.py beep when ready to flash?

Thanks for that, very interesting.

I'm still hoping to be able to use a custom version of esptool.py (instead of the packaged exe)... Or I guess could package it with PyInstaller?

Or isn't there some way to edit the command that the Arduino IDE sends to esptool?

Possible to have esptool.py beep when ready to flash?

I'm using an ESP32 dev board that requires pressing the boot button to flash it. The compile time in the Arduino IDE takes almost a minute, so I have to sit and watch the progress so I can press the boot button at the appropriate time. It would be really nice if I could hear a beep when it's ready f...

Can't upload more than 1 MB to spiffs?

I'm using this Melife ESP32 dev board: https://www.amazon.com/gp/product/B07Q576VWZ In the Arduino IDE I have the partition scheme set to "default 4mb with SPIFFS (1.2 MB app/1.5 MB spiffs)". However, if my SPIFFS gets any larger than 1MB, I get: SPIFFS_write error(-10001): File system is full. Is i...

Recommendation for a small but capeable ESP32 Arduino module?

I'm building an IOT product that would use an ESP32 Arduino board. Currently I'm using this Melife dev board: https://www.amazon.com/gp/product/B07Q576VWZ It works well (beautifully actually!), but the headers make it a bit too large for my purposes, and I can't find it without the headers soldered ...

Re: Advice to improve the stability of my script?

I made a little Python script to load test my ESP32 script, reading from the wifi interface of my ESP32 every second. I get timeouts most of the time, even with only 1 thermometer connected... Here's my script fyi (apologies for the Python 2 print statements). It expects a response like this (this w...

Advice to improve the stability of my script?

I'm reading 5 DS18B20 temperature sensors from an MELIFE ESP32-ESP-32S dev board, and getting crashes about once a minute. Sometimes it'll trigger the watchdog and reboot, sometimes it'll just stop responding. I'm hitting it pretty hard, reading the temps of all 5 sensors every 2 seconds. And I'm po...
