Can you tell me about the cheapest rasberry pi alternative and arduino alternative, i want something strong with cheap price
The best Arduino UNO alternative is the ESP32. The ESP32 module comes with built-in Bluetooth and wifi. There are many alternatives for the raspberry pi, the best alternatives are Orange Pi & Banana Pi. But the price of these boards depends on where do you live. If it’s available in your country then, it may be cheap for you else you have to import by paying an extra shipping charge.
I also think the best alternative to Arduino is the ESP32, because the ESP32 can also be programmed by using the Arduino IDE. But I don’t know much about Raspberry Pi, and I saw many people say ASUS Tinker Board S is a good choice.
Sir how to buy a bananapi in online I am from India…?
