extremely cheap ESP32-WROVER module

Electrodragon is selling ESP32-Wrover V4 Module at a price of 4 US$ (3.6 US$ if you register) + < 3 US$ shipping. I makes it cheaper than most of the ESP32-WROOM modules. Combined with a <2 US$ ESP32-WROVER Breakout Board , <1 US$ power supply ( linear or Switching ) and some ~1 US$ USBtoSerial , it...

Cannot wakeup from deepsleep

I have a strange issue with one of my ESP32 modules ( AnalogLamb's ALB32-WROVER ): the module cannot exit deepsleep once it enters it. Tested with deepsleep example from esp-idf ( esp-idf/examples/system/deep_sleep ). The example runs as expected on every other board/module I have, all wakeup source...

You can add the default settings to sdkconfig.defaults file in your project directory.

Thanks. For testing you can use esp-idf/examples/system/deep_sleep
If you are using AnalogLamb breakout board, don't forget to attach pullup resistors to EN & IO0 pins, they are missing on the board...

Re: No heap anymore after adding bluetooth in menuconfig

Ah thats why, I have the ALB32-WROVER. Guess I can use my current breakouts then. Thanks! Sorry for the post not related to this thread, but as you mentioned that you have ALB32-WROVER, I have an issue with the same module. I canno't exit the deep sleep. Tested with deepsleep example from esp-idf, ...

Wrower and Wroon has different footprint. There is also ALB32-WROVER which has the same footprint as ESP32-WROOM, but with 4MB psRAM included.

Re: No heap anymore after adding bluetooth in menuconfig

While I am also not aware of any breakout boards support WROVER... AnalogLam now has breakout board for ESP32-WROVER. It looks like it is sold without any component soldered. It would be good if AnalogLamb could release this board with all components (including ESP32-WROVER module) soldered, for th...

Re: No heap anymore after adding bluetooth in menuconfig

If your application needs a lot of heap, I would recommend using ESP32 with spiram . In small quantities you can get two modules from AnalogLamb , ALB32-WROVER and ESP32-WROVER. SPIRAM support is now included in latest esp-idf and xtensa toolchain, so there should be no problem using it. You will ha...
