🔑 Keywishbot BLE Nano V3.0 - Micro USB Board with Integrated CC2540 BLE Wireless Module and ATmega328P 5V Micro-Controller - Compatible with Nano V3.0 Review

I don't need it now because of the wrong description. I bought it to use with the MySensors network but there are compatibility issues that require reprogramming of all other sensors.

These modules are not worth the trouble. As stated, they are not 100% compatible. The two modules I received looked like they were poorly designed and made from defective or possibly counterfeit components. buy something else.

I want to use it to control a RC boat. But there were no devices because the advertised RF chip was different. It should contain the nrf24l01+ chip as shown in the picture and description, but instead the devices contain the nrf24l01 chip without the plus. Still thinking about bringing her back.

Pretty much what every other (negative) review states is true. Basic TX/RX connection cannot be established. Extremely shady custom USB driver that doesn't install well; also accesses multiple Arduino port interfaces and only mirrors devices on the same port. Doesn't work (as far as I understand) with known TMRh20 RF24 library; There are posts on the web that use the mirf library, but I couldn't either. I will refund the remainder of the order for a few units and return to known Arduino boards…

Hardware OK. Micro-USB is good (compared to mini-USB) and the basic Arduino Nano functions work. But the BT module interface is garbage. Documentation is garbage. shit firmware. You can connect it to BT module and send commands, but it is unreliable compared to other modules. Reloads constantly. Send wrong AT command? Be prepared to be answered with a "bad general". If they can't play the most common dialogues correctly without typos, you can be sure that the rest of the firmware is performing…

I ordered one of these, it wasn't working properly so thanks to Revain's return policy it was quickly replaced. Both arrived within a day or two. They show up as Arduino Uno in Device Manager and don't load under the CH340 driver. I had to set the Arduino IDE to use the old 328p bootloader or it wouldn't be able to communicate. Continued to get a connection timeout. I also tried using Visual Studio and encountered the same problem. Even after getting them to accept the download, they didn't…

I researched Adruino devices for a while and finally clicked on this one. I installed the Arduino IDE, set the board, processor and COM port options, and connected one of the RF nanos with the USB cable that came with it. Uploaded a simple sketch of LED Blink and here we go! Worked great as expected. Happy with that, I installed TMRh20's RF24 library. Using one of the examples provided, I had 2 nanos communicating flawlessly between rooms. As mentioned in another review, CE is on pin 10 and CSN
