Hi, I'm new to learning embedded and want to learn embedded/low level programming but currently don't have enough money for buying an stm32 nucleo board (which everyone suggests for seriously learning embedded programming) but my budget is currently limited to only 300-400Rs (3-4$), I found these two Arduinos but idk which one to choose cuz one is the genuine UNO R3 which is 2100rs (24$) and another is 334rs (3.7$) both have same specs when I saw: 2kb ram, 32kb storage etc..

Also, can anyone please tell me the Arduino on the left side (UNO R3 SMD) is genuine or a knockoff?

Also, if anyone is form india and bought the UNO R3 SMD please tell me the difference between this and the original UNO R3 🙏🏼.
