Hello, Is it possible to run VDD3P3_CPU at 1.8 volt while all other supplies are at 2.7 Volt? If so, is it safe to assume that all IOs will operate at 1.8 volt? Thank you very much in advace for help. Kishan Hi, Is it possible to run VDD3P3_CPU at 1.8 volt while all other supplies are at 2.7 Volt? ...

What is the difference between ESP32-WROVER and ESP32-WROVER-B modules? Does ESP32-WROVER-B has more PSRAM than ESP32-WROVER? Hi, They both have 8 MB PSRAM. ESP32-WROVER has PSRAM that operates at 1.8 V and can support up to 144 MHz clock rate. ESP32-WROVER-B has PSRAM that operates at 3.3 V and ca...

There, Sorry everyone, I don't know Baidu‘s pictures can't be viewed. So I reposted a post. On page 50 of ESP32_TRM_rev3.8.pdf , the table 18: IO_MUX Pad Summary . It write MTCK/ GPIO13 is IE = 1(input enabled) on after reset . But On page 58 of ESP32_DS_rev2.5.pdf , the IO_MUX list . It write MTCK...

4. No, you don't need to add caps between SVP and SCP, SVN and SCN, unless you want to use the LNA ADC.

Which is not supported. Or, is it?

No, it's not supported. Thanks for the reminder

Hello, I'd like to use ESP32-PICO-D4 in my motorcycle data-logger module. First of all - do i need anything more that things in "peripheral schematics" in datasheet to run module? Secondly - 5 meters of wifi range is more than enough for me, then do i need to make matching circuit (L5, C27, C28) fo...

Hi all, the TRM is now V4.0. Major changes span four chapters. The link remains the same: https://www.espressif.com/sites/default ... ual_en.pdf

Setting SPI_CLKCNT_H too high in SPI_CLOCK_REG register makes in some cases (probably depending on SPI_CLKCNT_N) stop SPI working. This is not documented.

PI_CLKCNT_H=⌊SPI_CLKCNT_N+1/2 – 1⌋, SPI_CLKCNT_N=SPI_CLKCNT_L

[SPI] CS setup time does not work in full duplex I don't think you realise how huge problem this is. Full-duplex is the most common setup and most SPI peripherals require CS active several clocks before the data transfer. In full-duplex mode, setting SPI_CS_SETUP results in 1.5 SPI clock cycles bet...

Hi,

ESP-WROVER-KIT now supports ESP32-WROVER-B with 4 MB flash. Custom order for 8/16 MB flash may be possible. Please contact our salesperson for more information. Thanks.
