That's why there are 2 capacitors not installed in C21, C12, and C10?
How do I reinstall the RF Shield?
Which IC is suitable to replace the Memory on this component which has the same leg size, planning to increase it to 64Mb?
ESP32 Wroom 32 / ESP32-D0WD
I count three capacitors in your list here. But C12 looks to be fitted.
As to the reason, then maybe you bought some knockoff rubbish from China?
I don't think there is anything that can increase the memory size of this processor. The Arduino Mega has a method of increasing the memory, but it is seldom used.
A quick search (i'm not an ESP32 expert by the way) found a question on the ESP32 forum from 2016 regarding SPI memory selection. Part of one answer says:
Size can be any of 1MB (8 megabits), 2MB, 4MB, 8MB, 16MB. Accessing more than 16 megabytes is not possible due to the 24 bit addressing limit of the standard SPI flash commands. Some larger chips may still work (as the they support 24 bit address commands also), but you'd only be able to operate on offsets above 16 megabytes via custom SPI commands (can't execute code from there, etc.)
How did you get it off?
just by heating the edges with a soldering station at 260 degrees plus flux. If you know that RF Shield is just soldered to stick it but because the tin is inside they solder using a heating board
Okay, I understand
Why do you need more memory?
You can add external memory on the I2C and/or SPI bus. No need to open the device.
if you know i'm making a small smartwatch project
