Replacing new MCU to my controller

[khaledkhalid]

Do i need to program a new MCU before solder it to my controller?

 

[StuartsProjects]

Which controller and which MCU ?

 

[khaledkhalid]

Ananda controller with stm32f103rct6 MCU.

stm32f103

Well normally that MCU can be programmed in-circuit, with the appropriate programmer and assuming the board has the appropriate connectors.

However, I dont know the internal wiring of the Ananda controller, so cannot know if it has the appropriate programming connections.

Its certainly possible, with the appropriate ZIF adapter to program the MCU before assembly.

So why do you need to replace the MCU ?

Do you have good experience of surface mount soldering ?
