Custom ESP8266 Board unable to connect

goes dark for another 2s. And yes, I know the design isn't really good, since it is my first ever ESP32 custom PCB _:) I am just trying to get this to work, so I can install WLED to it, then I can improve my design and do a 2. Rev

I am redesigning the PCB to use a already built microcontroller board, I am thinking of the XIAO ESP32, since building you own ESP seems to be rather unnecessary complicated. Thank you very much for every help provided to this point.

Need help: Using an ESP32-C6 to control 5V LED strip via Zigbee

think. Therefore any advice is very much appreciated :-) I would like to use a DF Robot Beetle ESP32-C6 Mini (https://www.dfrobot.com/product-2778.html) to control a white 5V LED stripe (like this one: https://amzn.eu/d/fjpVlmg) via Zigbee, so that I can integrate it into my Home Assistant (Zigbee2MQTT

ESP32-C6 Mini does not seem to have a 5V power out. So do you have an idea how I could practically fork the 5V power from the Beetle ESP32-C6 Mini's USB-C socket to the LED strip? I will only use some small

Need help with ESP32C3

Hello, when I try to connect to the WiFi with my esp32c3 I get this error and a boot loop...WHat can I do? [code] rst:0x3 (RTC_SW_SYS_RST),boot:0x8 (SPI_FAST_FLASH_BOOT) Saved PC:0x403cf94c SPIWP:0xee mode:DIO, clock div:1 load:0x3fcd5810,len:0x438

Pin, connect to this pins a capacitor to have a energy buffer. You can try 100µF. I added to my ESP32-C3 SuperMini a 1000µF capacitor and did get now a connection to my router. For this process it needs a lot of current.

ESP32 wireless data transfer of medium speed

Dear Readers, In my current project, I get data at 100Hz, meaning 10ms period. I want to send this preferably over bluetooth to an app, which I will code in React Native. Data: 2x float, 2x int The question now is if bluetooth is fast enough to send data in real-time, or should I use another method? There is a bluetooth BLE library for React Native which is quite good but i am unsure if BLE is the right choice for this, as i have heard that is quite slow in data exchange. I do not want to use Wifi because of some reasons. Thanks for your help

Two ESP32 together for programming

everyone, I'm quite new to microcontroller and prgramming. I already flashed some firmwares (with ESP32 development board) and programmed something for myself. For my current project (a LED lamp) I need a smaller controller, because of the limited size. So I decided to go with an ESP32 chip without the

I've changed the schema of this link: https://www.14core.com/wiring-and-flashing-programming-esp-32-esp32s-with-usb-ttl-uart/ a little bit to my needs and I_m not quite sure if this correct. Thank you in advance, Danny

How to adjust WiFi-channel for ESP-NOW

to adjust the Wifi-channel with ESP-NOW. Does anybody know how this is done for ESP8266-modules. ESP32 uses a different library so you can't jsut look up ESp32 and copy it for ESP826. Hallo, ich probiere gerade zwischen zwei ESP8266 Modulen (Wemos D1-mini) parallel ESP-NOW und Verbindung

Ich habe aber nichts darüber gefunden wie man bei ESP-NOW fr ESP8266 den Kanal einstellt. Bei ESP32 wird eine andere Library benutzt. Deswegen kann man die Erkenntnisse von ESP32 nicht auf ESP8266 übertragen. Jedenfalls nicht alle. Weiß jemand wie man bei ESP8266 den ESP-NOW-Kanal einstellen kann

MCU with WiFi and GREAT ADCs

have been looking all over the Internet and the MCU that best matches what I'm looking for is the ESP32. However, those ADCs specs are not enough for my project: I'm in need of a Microcontroller that has WiFi (integrated 2.4GHz antenna) and at least 12 input ADC pins (>=12 bit precision) with high

somethign available but most likely not available on a breakout board for <15€. I would use an esp32/8266 with an external ADC (breakout board if you want to), also because the Wlan could disturb the ADC measurements and add noise.
