But still... is the 4 MB of PSRAM maximum which can be addressed by ESP32? Or is the article outdated and is it possible to use all of 8 MB?

I just found this article: https://thingpulse.com/esp32-how-to-use-psram/

Dear community, I allways used ESP32-WROOM module. But some my projects uses video buffers with size in hundreds of kB of SRAM. The SRAM limit of this module is 512 kB which is crazy low. But I came across the ESP32-WROVER module which has the same size of SRAM (512 kB) but it also has PSRAM in mega...

Dear community, I have working Bluetooth LE code for communication between ESP32 and Android / Windows 10 App. I am using these Arduino libraries: #include <BLEDevice.h> #include <BLEServer.h> #include <BLEUtils.h> #include <BLE2902.h> The only problem is that connection least only 10 seconds. After...

Do not worry! You helped me very much. I will find a different LDO by myself - At least I will learn it by myself.

Hello,
almoset every regulators have multiple packages. I can customize the PCB. Components may not be available in my country other than in yours.

What about: AP2114-3.3 (SOT-223) ... looks same like LD1117 for me

Thank you.

Dear mikeymoy,

I preferm linear stabilizators because of minimal external components. Which parameter should I look at if I want use it for ESP32?
I need 3.3V with minimal 500mA because I use only Bluetooth LE (no Wifi).

Thank you.

Thanks mikemoy, I did not notice that LD1117 is slow. Which cheap 3.3V regulator would you recommend?

Thank you pataga.
Large capacitor and slow discharging sounds logically. I do not want to add another component to my circuit. I have added big capacitor because of wifi voltage interference but now I am using only bluetooth so I will remove it. For bluetooth it is useless.
Thanks.

Dear community, my ESP32 board reports a brownout detection ONLY while connecting and disconnection it from the power source. I belive my power source has all neccessary components but maybe I miss something? - Power source is standard adapter with output 5V/1A - ESP32 is powered via LD1117 LDO regu...
