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

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 with the NRF radio as an attached item. I would suggest that the seller post a working TX/RX code to dispute or confirm what all other reviews (negative or positive) are saying about the device.
