With crowpanel 2.8inch ,
I'm trying to connect the product to the ublox m8n module and the DF player mini module. There are three ports: UART1, I2C, and GPIO_D. Where should I connect each of them?
each module have RX, TX, VCC, GND (UART)
If I connect the gps module to uart1, and DF player module to GPIO.,
I need to use software serial, but I heard that software serial cannot be used on esp32.
You can wire it this way and ESP32 supports soft serial port, but the effect of soft serial port is not as good as hard serial port and there may be data loss.
Optionally, you can use crowpanel 2.8inch in this way: u-blox M8N GPS module: Use UART1; DFPlayer Mini: Use GPIO_D, configured as UART2; Use the UART0 on the Type-C interface for serial debugging and powering, thus avoid the need for SoftwareSerial.
CrowView Note's keyboard and touchpad are sometimes unresponsive
The customer investigated whether it was a problem with the usb port and the bridge kit by switching to a usb cable to connect the croview note to the Raspberry Pi, and switching to a different usb port on the Raspberry Pi.
Insufficient power to the screen blinks, asking if it is possible to connect one of the two touch/power ports to the power supply and one to the touch input.
Yes, it is possible.
Need some technical assistance on ThinkNode G1 LoRaWAN gateway.Is there any firmware of upadation for changing LoRa frequency band to IN865 frequency. If present can you kindly share us the firmware with detailed steps on how to add LoRa frequency IN865 to the gateway?
Only European and American bands are supported
CIR12704M : SIM7670 4G Module - Not recogonized with stock Raspberry Pi OS?
1.As the 4G module needs to do power-on timing processing, this aspect is made into a script and this script is required to autostart , so in the image we provide there is this boot up script, but because the new image does not have this script, so the 4G module can not work.
2.The link below contains the startup script for the 4G module. It only needs to be powered up and given a high-level signal to the 4G module. You can install it on a fresh OS.
with a OV264 camera and now I look for a Arduino surveillance video Sketch
Is there a project page there I can find it or any other example sketch with the OV264 camera
Please see the attached about example sketch with the OV264 camera.

I have been trying to compile and upload code to a 5" HMI display. This code is a vary simple program using the lovyanGFX library. I can upload and rum code using the Arduino IDE. However I normally code using VSCode and PlatformIO, but when I compile and upload using platformIO the ESP32 output memory errors to the serial monitor. I have tried various combinations of parameters in the platformIO.ini file but can not make this work. Is there a sample platformIO.ini file that will owrk available anywhere?
Please refer to this tutorial page: https://www.elecrow.com/wiki/5-inch-esp32-dispaly-platformio-tutorial.html
You can download the platformio project file at the bottom of the page: https://www.elecrow.com/wiki/5-inch-esp32-dispaly-platformio-tutorial.html#resources
Please note that for the v1 board, your need to press the BOOT button then press Reset to let the ESP32 chip to go into downloading mode.
today i got my GrowCube, but it seems it dies Not work correctly.
In my App on my Handy does it look like that
Iphone 14 Pro Max and iOS 18.1.
growcube is updating the app for iOS18 and is expected to be online by the end of May.
Is it possible to integrate it directly into my home assistant and use it to display temperatures and show buttons on the screen.
What I'm trying to say is, can I integrate it in as is or is it necessary to buy other hardware and use it as a monitor only?
The ESP32 Display works with the home assistant. If you want to use it to display information such as temperature and humidity, you need to connect additional sensors to detect the data.
I saw and checked Elecrow's official Wiki.
https://www.elecrow.com/wiki/lora-basic-gateway-module.html
But, I encountered problems when I upload the programs to module.
I attached error messages in mu error message from Arduino IDE.
This error may be due to a missing system header file for ESP32. Make sure his download settings are set up for esp32. esp32 motherboard version needs to be 2.0.14/15.
