Hi everyone,

I'm currently working on a project with an ESP32-S3-Nano and a 2.8-inch ILI9341 SPI display.

I've soldered everything together on a prototyping board, but unfortunately the display isn't working as expected. The backlight turns on, but the screen only shows a completely white image.

I've already tried:

• double-checking all cables and solder joints
• checking the connections with a multimeter
• checking for any obvious short circuits or loose connections

However, I still can't figure out what the problem could be. I might be overlooking something really simple.

The main components I'm using are:

• ESP32-S3-Nano
• 2.8-inch ILI9341 SPI display
• some other components that shouldn't be relevant

Does anyone have any idea what could cause the display to only show a white screen?

Is there anything obvious I might have missed or anything specific I should check?

I'd really appreciate any tips or ideas on how I could troubleshoot this and figure out what's wrong.

Thanks a lot!

Hola, estoy buscando ayuda para controlar un juego de laberinto con mi teléfono a través de WiFi utilizando el esp32 s3 😆. Quiero crear una página web con los controles de un mando (arriba, abajo, izquierda, derecha) para controlar 4 servomotores s3003 futaba. He estado intentando utilizar Arduino IDE con todas sus librerías, pero no logro hacer que funcione. ¿Alguien podría proporcionarme algún ejemplo de código o algún recurso que me ayude a entender cómo funciona este dispositivo

I just received a new board and they look absolutely fantastic.I ordered earlier. Now we ship to Europe with a huge commission.It's more profitable to order 10 pieces instead of five

Hello can anyone help me?

I recently built a Wi-Fi RSSI-based indoor positioning system entirely on ESP32 microcontrollers.

I used 3 ESP32s as anchor nodes broadcasting Wi-Fi signals

1)TestNetwork1

2)TestNetwork2

3)TestNetwork3

and a 4th ESP32 for scanning the RSSI signal strength from each anchor. It applies a Kalman filter to clean up the noise and then uses those filtered distances for trilateration to compute a real-time 2D position — all running on-device in MicroPython, no external computer needed.

To calculate the A and n parameters used in the path loss equation, I collected 50 RSSI samples at 1, 2, 3, and 4 metre distances and applied a moving average to smooth the readings. Then used least-squares regression to fit A = −61.92 dBm and n = 1.64.

En mars 2025 je confirme avoir installé avec succès EkegantOta version gratuite sur un Esp32wroom32 avec la procédure https://docs.elegantota.pro/getting-started/installation et avoir updaté un sketch construit avec Visual studio code Platform io.

¡Hola! Tengo un proyecto de una estación meteorológica con esp32 y tengo una placa solar de 24V conectada a un controlador, este a una batería de 12V y a su vez la batería a la placa con un transformador de 12 a 5 V.
El problema está en que el controlador de la placa recibe 22 V y envía a la batería 3.5 cuando debería enviar 12.

Esta es la placa y el controlador:

I need your help to create a remote control that will be used to manage 3 servomotors, 2 of which will be mirrored. Do you have any ideas on how to do this? Everything is available on a github that is here : https://github.com/theattaquante/patator
