I don't know how to get a picture in here. But as I wrote before, the usual suspects are not used
IO12 = unused
IO2 = unused
EN with 10k and 1uF,
RXD = IO3, TXD = IO1

What could trigger such a behavior of the ESP? So minimal power consumption and no output of anything on serial port?

I'm pretty clueless :( What can lead to the ESP consuming so little power and not showing any signs of life? I always believe in my stupidity, but since I've used the part many times in different circuits, I'm at a loss. Conspiracy theories - is the chip empty or fake? :shock: IC-label: ESP32-PICO-V...

I often use the ESP32-pico-V3-02 in various circuits and have not had any problems communicating with the device. Now I have a circuit board with this IC, where no communication is possible at all, I tried it on 3 identical circuit boards to rule out any hardware or soldering errors. Apart from the ...

I don't have a solution yet. When the BT is active, no more data can be received... maybe there is a collision in the interrupt setting. If anyone has an idea for a solution, that would be great.

Hello, I have a problem - Chip is ESP32-PICO-V3 (revision 3): When I use UART2 it only works when Bluetooth is not active. When BT is activated, no more data comes via UART2. Communication runs normally via UART0. I used Serial. and Serial2. I need to realize the following: - Communication "CONSOLE"...

Hello guys, I am interested in "IrDA for Datatransfer in both directions" Which register settings do I have to make there? Sending OR receiving is not a problem... only sending works with this: WRITE_PERI_REG( 0x3FF6E020 , READ_PERI_REG(0x3FF6E020) | (1<<16 ) | (1<<10 ) ); //UART_IRDA_EN + UART_IRDA...

The standard SPI connection on the ESP32 is:

HSPI VSPI
CS0* 15 5
SCLK 14 18
MISO 12 19
MOSI 13 23

Pins 18 and 23 are not connected on the pico-V3. Which pins are used for this?
18 -> ?
23 -> ?

Thanks.

Thanks.
That's exactly how I thought it, just wanted to be assured by a professional that it really is.
The answer was that simple and quick. Thanks again.

Since it is not possible to get such a simple answer in advance, I have to test it myself
It is comparable to the first step of mankind on the moon, nobody has programmed this chip with Arduino before.
