Keep experimenting with this 3$ Adafruit chip-based display in the process of writing a stm32f10x library for its usage.

Forgot to update - the EEPROM worked as expected. Apparently i could use another technique of SMD soldering:
Damn, forgot to use flux! Would make the whole process much easier. Anyway this is my first soldering experience ever, so the result is good enough.
I wanted to get a EEPROM device and ordered one - it costed around $0,60 - so ideal and cheap. But after receiving it, i found out that the size is more than twice smaller than i expected, around 5mm. Today i learned it's a SMD chip in a SOIC8 package, not quite what i expected. Fortunately, it was easy for me to find a SOIC8-PDIP8 adapter and PLS pins in the local microelectronics store. Unfortunately though, i don't have a soldering station fith a fan, only a $0.5 soldering pencil.. Let's try to use it for this purpose.
This morning I have been trying to solder it perfectly by using a soldering paste with a soldering pencil. Not surprisingly, the pins were getting bridges in between, so i started from zero several times. After a lot of time and struggle, the process is finished XD. Tomorrow i'll check whether the EEPROM module works correctly.
