For beginners as well as intermediate makers i prefer Arduino Micro or Leonardo. It is very easy to use like an Arduino UNO or Nano and has the same features of ATmega328P as well as a must-have feature support built-in USB and can use it as a USB host Device or HID device. I also prefer Arduino Nano boards rather than using Arduino UNO boards because of its size only.

For simple and minimal projects i love to use ATtiny 16/84/85 microcontrollers(My own boards) or digispark boards. It is cheaper smaller in size and works with ultra-low power mode.

In the IoT perspective, I prefer ESP8266/ESP32 boards if you want to add wifi/BLE features into your project. The cheapest and the best solution for IoT projects so far. Have large community support and supported by different programming platforms like Arduino IDE, MicroPython, ESP IDF, etc.... Esp32 is a powerful 32-bit microcontroller capable of wrapup any heavy project we think!

@salmanfaris Actually I'm not sure what was that Core 0 register dump:
But I parsed the JSON. Refer Here for cJSON example. But while working this one, faced another problem. HTTP response includes the whole headers, status code, and body. JSON parser only work if the whole response in the form of JSON. So, Initially stored all responses into a char buffer and cleaned all headers. By using if(response[i] == '{' ) and some flags.

Hi @Anish_Pillai , Are you using the TP4056 standalone module or specific breakout/ready-made boards with NodeMCU?

You can refer to the circuit below if you use generic readymade modules.

@saheen_palayi Photon2 is now available at $ 17.95 on their official store page, soon it will be available on the Indian website. I was able to grab it once and will ping you once I received it.

@sarathslab why your are choosing this perticular LoRa module, can you please elaborate your use case. Personally I don't have experience with this module. When i go through the details of this hardware find like this is a UART device and so you can communicate by using the AT comments. And this will be available on the datasheet I guess. Also if you don't want to use this perticular module I suggest sx1276 or LoRa E5 from Seeedstudio. And by using this you can able to connect with helium network or things network. If you want to know more about this I think Salman can help.

@binishmatheww All the best. Let us know if you need any help.
