CP2104-F03-GMR device descriptor request failed
-
Hi guys,
I have made a custom PCB with CP2104 USB TO UART Bridge. You can find the schematics realted to the USB below. After getting the PCB fabricated, when I plug into my computer it is showing as Device not recognized - Device Descriptor request failed. I tried lot of methods but no luck. Uninstalled the drivers using the instructions suggested in this thread . But nothing worked and i am using a Windows 10 PC. Please help me out with a correct solution.
The board is powering up properly. please someone suggest me a work-around...!! Thanks

Hi @kowshik1729 , The connection between the CP2104 and ESP01 seems looks ok, can you share a more clear picture of the Automatic IO, EN toggling Circuit. Also double-check the trace continuity with a multimeter too.
-
@salmanfaris oh no....the UART Bridge is not for the ESP-01. There is an ESP32-Wroom SoC, and yeah I shall share more info.
-
@kowshik1729 Okey, I come with conclusion from the right bottom side esp01.
-
@kowshik1729 Did you solve the issue?
-
Not yet @salmanfaris .

In this second edition of MakerCuriosity Podcast Series by MakerGram, we are discussing programming Microcontrollers using Python.
The discussion includes how exactly an interpreted language works on a Microcontroller?! Besides that, we have covered the pros and cons and when it is preferred to use Python on Microcontrollers when 95% of existing embedded code is written using either C or C++. Listen now and let us know your feedback and opinion!
Stay tuned till we meet with another exciting topic on next week!

Hi all,
I recently came across this post where they have shown photos printed on PCB in high resolution. I would like to know how to add this kind of photos to the silkscreen layers of the PCB in Eagle/Altium.
Adding such kind of photos will be attractive for beginners and also can be used for educational purposes too.
Please let me know in case anybody knows. -

The license of the https://dl.espressif.com/dl/package_esp32_index.json might be expired(If this is the reason you can't do anything but just wait until they re-activate the license)

@abdultechguy999 usually https://dl.espressif.com/dl/package_esp32_index.json this works while installing through boards manager. But I faced the same issue some times. it might be due to a couple of reasons.
Bad Internet connectivity
The license of the https://dl.espressif.com/dl/package_esp32_index.json might be expired(If this is the reason you can't do anything but just wait until they re-activate the license)
I remember there is a way to install the board files offline by downloading from some github repos.
All the best.

Ok, then you need to check the LM2596 output current and voltage!
