What's your favorite embedded/prototyping development board?

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!
@binishmatheww All the best. Let us know if you need any help.
@salmanfaris thanks a lot.
@binishmatheww There will be a single device, but I can't find one for now that has both GPS, GSM, BLE and USB Support.
Also, can we have all these data transfer modes in a single module?
You can make the priority and depending on that it can switch different modes.
Transfer the data via Bluetooth if is connected.
This can be achieved with BLE transfer.
Transfer the data via a USB cable if it is plugged in.
It can be achieved via Serial communication or USB HID profile.
Transfer the data over the internet.
here, we can route the data to the cloud over the phone or directly to the cloud via a GSM module or WiFi. I think it will be overkill if we use an external modem, better to cache the data and push to the cloud via phone and BLE if the live data is not needed.
@salmanfaris thanks for the reply Salman .Transfer the data via Bluetooth if is connected. Transfer the data via a USB cable if it is plugged in. Transfer the data over the internet.
Is it difficult to transfer the data via a USB cable instead of Bluetooth?
Also, can we have all these data transfer modes in a single module ?
If we have all these modes in a single module, will it increase the processor load ?
Hi @binishmatheww , Welcome to Makergram.
After that, you need to choose a microcontroller, which can communicate with the GPS module read the GPS and translate the NMEA (data format for GPS packets) to a more usable format (you can do the post-processing in the phone too).
Then you can send the data to hone via BLE, for this you can use a BLE-supported microcontroller or use a standalone BLE co-processor. My suggestion is to go with esp32 as it has BLE support and other cores can be used for the GPS data acquisition. To do the post-processing and other things you can do with the mobile app.
You can split the project into different parts.GPS Data Acquisition. (You can use Arduino IDE + ESP32/Pico W + GPS module of your choice) GPS data translation (There will be Arduino lib which can make the translation easier) Send Data to the mobile app via BLE (Arduino IDE + ESP32/Pico W + BLE LIB + Mobile application).
Hope you get an idea, please check and let us know. Happy building.
