QuestionFor the battery pin, what is the lowest and highest allowed voltages ?Thanks

is there any way to prevent the green battery led from blinking?
(besides physically removing it from the board 🙂)

My intention was to use this board to publish sensor readings with MQTT. I'm using the Arduino framework together with the Arduino IDE. But this board type or the ESP-C6 seems to have major issues with network based communication.

I tried several libraries (PubSubClient, espMqttClient, paho.Mqtt) and all of them causing network errors.
The WiFi connection is fast and reliable. But the WiFiClient and WiFiClientSecure are causing almost everytime a connection failure. After a fraction of a second the client reports (-5 - Connection failed). Only one out of 20 connections works. Same for HTTP based connection. They work a bit better, but most of the time they also fail.

I tried with mqtt:// and mqtts://, local network as well as remote with absolutely the same behavior.

Is this behavior caused by a bad batch of boards, bad board design or is rhe ESP32-C6 not capable at all to work with WiFi relieably?

I have two of these boards (naked nothing connected). But using the same sample codes with a Firebeetle ESP-E, evetything works reliably all the time.

I intended to use this board to connect it with a dfrobot SHT40 breakout board. Both are very tiny and would match perfectly for a smart ESPHome sensor.

Unfortunately, the pinouts of the two are absolutely not identical, which means I cannot just solder the header pins and connect them. 3v3 and GND are in the wrong order, and with this also the SDA/SCL.

Any ideas how I can mount the sensor easily and compact on the back of the ESP32-C6 Mini, to have a minimal footprint?

Thank you for the fast response. I don’t see a link to any sample code. Did I miss something?

HI, is there is any way to know whats is wrong with my board because the green onboard led (c) is blinking so many times and I have upload code, ans is not working even if the code was successfully uploaded. This is code. Even I cant see any pint ...
int led = 15;

void setup() {
pinMode(led, OUTPUT);
Serial.begin(9600); // Initialize serial communication at 9600 baud rate
}

void loop() {
digitalWrite(led, HIGH);
Serial.println("LED is ON"); // Print message
delay(8000);
digitalWrite(led, LOW);
Serial.println("LED is OFF"); // Print message
delay(8000);
}
.

I connected my battery to BAT and GND pins. do I short to VIN from BAT to get it to power from the battery? Does it cutoff the voltage automatically if it gets too low?

Looks like in the Wiki there are 6 PWM pins but I cant tell which. Im wanting 3 to 6 PWM, Wifi/BT, and 1 analog in. Any assistance would be great! Also how should a battery be connected such that it charges when a usb is plugged in and also can power the board when usb power is removed?

I think this one is a pressure resistor. Which means you may have to design your own circuit.

Hello,
May I ask what is the output form of your force sensor? If it is I2C, we have sensors with I2C output.
If it is analog voltage output, this ESP32 has 0~3.3V ADC to connect the sensor.

And for battery, this ESP32 supports 3.7V Lipo (charge cutoff voltage is 4.2V). And with our ESP32 controller's on-board charging circuit, you can simply charge your battery via USB.

What is the pin spacing both vertical and horizontal - in other words, will it fit on a standard 0.1 inch spacing breadboard?

Hello, According to the product description, there are three UARTs available,
one of which is designated for low power use. The pins allocated for the
regular UART are mentioned as GPIO16 and GPIO17, while GPIO4 and GPIO5
are allocated for the low power UART. My question is which pins allocated for the remaining UART? Additionally, I'm seeking
guidance on how to utilize the low power UART and another UART(without GPIO 16, 17) within the Arduino IDE environment.Thanks!

Which pin can wake up when deep sleep mode?

Hi, this says it supports i2s, but on the pinout there are no i2s pins. I want to connect an i2s mems mic like inmp441.

I see no mention of ESP-NOW. Does this chip support it?
