Hi @morphee909,
What are you using for the SD_VDD?
Thanks
Alan

Re: ESP32 Vs Micro SD issue
Hi,
Sadly not, I still have the issue. When I solder wires onto an SD to Micro SD card reader and put in a Micro SD card, I can read and write to it fine. I just can't to anythign else.
Regards
Alan

Minimum ESP32 circuit required for runtime
Hi all, I normally use an 'ESP32 Dev Kit C' for my projects. This time I want to create a PCB and solder an ESP32-Wroom-32D chip direct to it. This will make my project much smaller. So, I have bought 5 of the below: ESP32.jpg Then, I made the below circuit as I think it is the most basic that I nee...

Re: Help to build a minimal EPS32 PCB
Hi ESP_Sprite, Again, thank you for your help. I really like the idea of off-site buttons, I never even through of that. I think it will be best to keep the Reboot button on the board as I can see times it won't be as simple to power cycle the device, but having the Flash/Program button off-site on ...

Re: Help to build a minimal EPS32 PCB
Hi ESP_Sprite,
Do you think my two schematics are ok?
I know it is the Chinese New Year, but desperate to get a test mock-up PCB designed so I can test out my designs.
Many thanks
Alan

Re: Help to build a minimal EPS32 PCB
C7 and C3 are in parallel with eachother, so you can remove one of them. Suggest to make whichever one remains 1uF instead as is advised in the datasheet. Also, in my experience, if you don't use the exact transistor as on the devkit and you have issues with the auto-reset circuit, it can help to m...

Help to build a minimal EPS32 PCB
Hi all, I have bought a load of the 'ESP32 Dev KitC-V4-32D' and I love them. I am mainly using them to create dataloggers. I want now though to make my own PCBs and put the ESP direct onto it rather than have to solder on the Dev Kit (which costs more money and is a lot larger). I have taken a look ...

Re: ESP32 Vs Micro SD issue
Thank you @chegewara for your comment.
I am though using a Micro SD card in a plastic adapter (which works) and then direct to Micro SD card and it does not work. That is what I don't understand. Do you see an error in my wiring?

ESP32 Vs Micro SD issue
Hi all I have been looking at some projects that need me to read/write to Micro SD Cards. I followed the 'standard' SD Library @ https://github.com/espressif/arduino-esp32/tree/486a4c66c42a09c73586ffb50b67bfbe9cb1e502/libraries/SD . I took my soldering iron out and was able to recreate the below, it...
