Dear Alex, The voltage range of 2,3V to 3,6V listed in the datasheet is for each individual power supply pin. However, in actual application,we mostly use single power supply(VDD) and flash is connected to VDD_SDIO for low power consideration. Operating voltage of the flash that integrated in ESP32-...

Hi PaulShaw,

What about the driving level of the 32.768kHz crystal that you use?

The rtc_clk.c can be used to adjust the drive strength, but this file will only be included in our next version of IDF.

Currently, you can apply rtc_clk.c by sending e-mail to our FAE.

Thanks.

Hi, Please help confirm if GPIO0 is connected to output of the oscillator or clkout of the phy? You can try to connect GPIO0 to clk output of the oscillator and make enable pin of the oscillator can be controlled by ESP32. When ESP32 is powered on or reset, EN_OSC should be low at first and once app...

Hi,

You can add an external pull-up resistor of GPIO0 to make sure that it won't be pulled down by EXT_OSC_CLK.

If problem still exists, please let us know.

Thanks.

Hi,

Below are three kinds of ESD protection diode that can be as a replacement.

Hi, We recommend you to use SPI interface of ESP32 to connect external chip with CAN controller and CAN driver integrated. Because current beta version ESP31 has no CAN controller internally and only ESP32 does have CAN controller. BTW, besides SPI interface of ESP31/ESP32 can be used to connect spi...

Dear Rudi, C11 and C12 can be used as the sample capacitors for internal switching amplifier. Application scenario 1: with C11 and C12 You can get a high-precision amplifier which can sense the tiny voltage between SENSOR_VP and SENSOR_VN. Application scenario 2:without C11 and C12 You can get 4 cha...

Dear Rudi, There is something wrong with silkscreen of the first version of ESP_Module. P.S. The second version of ESP_Module has already fixed this error. The actual pin order of ESP_Module is just as shown in the ESP_Module_Testboard which is GPIO5, GPIO17, GPIO16. Please neglect the silkscreen of...
