I connected my MKR1000'S power using a USB cable only. After a while, the charge light started blinking, any issues with this type of setup? It has been working for two days already but previously, I have the same setup, it failed a month later.
Thank you.

connect a battery and it will stop
Your topic has been moved to the dedicated MKR1000 section of the forum.
Hello killzone_kid,
Thank you for your reply. I am sorry. This is not what I am asking - I just want to connect its power through the USB port ONLY. I don't mind it is blinking but I do mind that it stops working when it sends my data to the ThingSpeak server.
Thank you.

I'm not familiar with your board. How does it fail?
Why do you think this is connected to LED blinking? What actual evidence you have that LED blinking causes failure in a month? Let’s hear it, please!
Sorry, I should give more detailed info. My first MKR1000 - run from 8/13/2022 to 9/16/2022. I know it failed because it stop sending data (temp/humidity) to the Thingspeak server. This device was connected using USB power. Since this device is still under warranty, I received a new replacement. With this new replacement, I updated its firmware from v19.4.4 to v19.6.1 yesterday (9/22/2022). Here is the link - https://thingspeak.com/channels/1832269. It is working well so far. I just want to make sure it will continue to work going forward; that is why I want to know whether this type of power connection will cause any issues in the future.
Thank you.
Additional information on the fields in my Thingspeak server.
Field 4 Chart - counter. Its initial value is -525960 (a negative number here) which is the number of minutes in a year. Since I update my data every minute, I use the above number to count backward (counter = -525960; ++counter); by end of one year, the value should 0L. If my MKR 1000 device stops its updates, this counter will stop as well; this is a quick way to check whether my device is working or NOT :).
I hope this helps.
It doesnt, but good luck with your project and see you in a year
Killzone_kid - many thanks. I will let you know in a year :).
I have been experiencing a similarly maddening problem with a MKR WiFi 1010. This is an autonomous project, solar powered. The board wakes up once every half hour (via external timer) and connects to WiFi for a minute every day to send out telemetry. It has been randomly failing about once a month. When I open it up the board is frozen and the yellow CHRG LED is slowly blinking. There is no LiPo battery connected to the board, the system runs off a big 9V battery pack and the Arduino board is powered from a dedicated 5V regulator feeding the Vin pin. It is crazy because 999 times out of 1000 everything works OK, but it's the 1 in 1000 power-up cycles that fails.
