Emakefun BLE Nano with Wireless BLE and Micro-USB Interface,TICC2540 Chip,Compatible with Nano V3.0

This tiny Arduino-compatible microprocessor includes onboard WiFi and Bluetooth. That’s nice, but neither the WiFi or Bluetooth equipment uses Arduino drivers and Emakefun has not made it easy to get them installed. I gave up on that because I didn’t require those features. But I would have liked to get them implemented and it was taking a lot of time to figure it out.

Cute little board and inexpensive. However, while you can load and execute normal Arduino code to it, if you need the Bluetooth functionality it is not compatible with the Arduino BLE libraries. The Arduino Nano 33 or Nano 33 Sense are better solutions for those needing the Bluetooth functions, but cost more...

I bought this for doing a simple microprocessor task; I want to light up some drums when hit. I used the Nano protocol, with the ATMega 328 Old Bootloader, and it uploaded. Still have as yet to see if the whole circuit works, but so far, it seems pretty well made and it's blinking... will see if it works soon!

This product don't use ArduinoBLE Libraryonly is possible use the BLE passthrough to the USB cable via Serial using a AT CommandsRead the documentation before buy.

I have other Arduino modules working with separate bluetooth modules and they all work just fine even with lots of other libraries included in the software. However, this BLE Nano board appears to have a problem with a number of other libraries which cause it to not work reliably and in some cases not at all. While there is detailed schematic of how the mfr integrated the bluetooth to the Nano, it indicates there should not be any problem but there is. It could be any number of issues relating to settings with the BLE chip.If your software is very simple and does not include other hardware related libraries (like A/D, DA, Clock, etc) then this combined Nano and BLE module might work for you. In the project I tried using it, it does not and I will have to go to a separate BLE module which I know will work.

Pcostly for a clone, but only nano that i know of that will allow 5v input vs 3.3v.

This product is not compatible with the Arduino BLE library. I just returned it and bought an Arduino.

make sure you check over good for connections other then that good buy
