Esp32 wroom variants
Posted: Sun Mar 24, 2024 9:50 pm
I bought two esp32 from two different places. Top one from local seller the other from aliexpress. I have a weird issue It could be due defective product or me buying the wrong variation but I need to understand the difference so I can buy the correct one. Top one when connected to power bank it works EVEN when power bank is charging Also if I connect to power supply giving 4.2v it still works fine.
Lower one connected to power bank when it charging doesn’t work keeps restarting same with the 4.2v
Tested the lower one with power bank it was turning off when used with the top one. With the lower one it didn’t turn off.
Looking deep into the circuit I see some differences near the micro usb
Any idea what’s going on here?
