It does however work when the Micobit is connected via the battery pack. Any ideas as to why this is happening? I cannot find any information online.

]]> Twitching servo when used with Crowpanel 7.0 https://forum.elecrow.com/index.php?p=/discussion/837/twitching-servo-when-used-with-crowpanel-7-0 Thu, 29 Aug 2024 09:49:09 +0000 Elecrow HMI Display atrus2905 837@/index.php?p=/discussions Hello,
In my project I am using a Crowpanel 7.0 in conjunction with a Crowtail servo plugged in the GPIO_D port.
I am witnessing something weird, which is that, when I touch anywhere on the screen (not only on sections that would cause the servo to be operated), the servo begins to twitch (it does not change position, but there seems to be some kind of vibration/white noise occurring in it).
I tried to test the Lesson 09 tutorial code to see if I had the same behavior, but I did not manage to get it running (the screen is showing black when the code finished loading). I used a modified version of the ino file that I got from https://www.elecrow.com/wiki/ESP32_Display_7.0-inch_HMI_Arduino_Tutorial.html#design-ui-file-with-squareline-studio, and that I modified a little bit as well. You will find the ino file linked to this message. I changed the type to txt in order to be able to link it.
Have you witnessed this kind of behavior before? If so, can you give me some tips on how to solve it, please?
Have a great day!

This is a high-performance LTE Cat1 wireless module from the Crowtail series, featuring the SIM A7670E communication module from Simcom. It supports 4G data transmission and voice communication through a UART interface and is compatible with multiple LTE bands, including B1/B3/B5/B7/B8/B20, as well as WCDMA and GSM networks. The module also supports various protocols such as TCP/IP, FTP, HTTP, and multiple satellite navigation systems such as GPS, GLONASS, and BDS.

The module can be powered by a 3.7V lithium battery or a 5V type-C interface and has a charging interface. It also features a 3.5mm headphone jack, which can be used for making and receiving phone calls by connecting a headphone with a microphone. Its compact size makes it easy to integrate into IoT devices, and it is widely used in IoT, smart home, automotive, and industrial control fields due to its low power consumption and reliable performance.

When paired with the Crowtail base shield for Raspberry Pi or Arduino, it can quickly build 4G-related projects with these boards.
