MicroSD card breakout not working when connected to power bo

by arminaa on Sat Jun 13, 2020 6:41 pm

Hi,

I have an Arduino Nano 33 IOT connects to a MicroSD card breakout board, a PCF8523 Real Time Clock and a AS7265X (spectral sensor). Interestingly, I have uploaded the code using Arduino IDE and it works perfectly and open a .text file on MicroSD card when it is connected to pc using usb cable. But, when I connect it to a PowerBoost 1000 Charger with a Lithium Ion Battery - 3.7v 1200mAh, the sd card does not work and there is no .text file save on the sd card. Then I connect it back again to pc and compile the code and it works perfectly!!! I wonder what is wrong as I have check all wires and soldering but everything seems right to me.
Please find the attached image shows all sensors and how they are connected..

I appreciate If anyone could assist me.

Thanks,
Armin
