The LoRa project is excellent and just what I need on my 10 acres (4 hectares) of homestead. I have designed a universal ESP32 circuit board and it was made by a China supplier and I have ten units. On that board I used the pinout of your SD card module therefore I need to obtain a supply of modules with that pinout which is less common than some other pinouts. I used your link to Banggood and they are ‘out of stock’. I would like to get 5-10 of these with that pin out. Can you recommend another source with that pinout?
The ESP32 course is excellent and I admire your designs and ability to teach. I am retired from a career as an embedded controls engineer, mostly in vehicle power-train controllers and some medical applications. I worked as a one man corporation (DSB Engineering, Inc.) so I have the background to appreciate your work.

Hi Douglas, thanks for your continuous interest in my work! I’m glad you enjoyed the new project!
Thanks for letting me know, this MicroSD Card module should also work just fine. It’s slightly different, but it should work exactly the same (it has the same pinout GND, VCC, MISO, MOSI, SCK, CS).
Yes, there are many with vcc and gnd next to each other, but your early projects had boards with pin order of 3v3,cs,mosi,clk,miso,gnd and I am finding that impossible to find. If you do not have a source of these, I will have to adapt my board with external wires to swap pins. Thanks, Doug
You can find those modules on Ebay here with the exact same pinout as mine!
I hope that helps,
