Review on Black Socket Adapter Board for 8PIN NRF24L01 Wireless Module (5-Pack): Enhanced Connectivity Solution by Ashwin Chauhan

The positive side of this product is that once you plug it into Arduino 5 volts, connect cables and nRF24L01 module, easy nRF24 client/server Sketches for such drivers as RadioHead work immediately. After trying unsuccessfully to filter capacitors without an adapter, this adapter provided a solid platform for stable 3.3V voltage for RF applications. Just make sure the adapter is connected to 5V and not 3.3V if you are using a MB102 breadboard power supply or similar device. Note that the illustrations clearly show that the mounting holes, approximately 1mm in diameter, are covered with solderable metal material. The blocks I received appear to have this mounting option, but the holes are lined with what appears to be the same non-metallic (multimeter tested) PCB plating as the rest of the board. I would like to hear from the supplier how you should mount them as they cannot be soldered to a terminal block unless you want the coating to evaporate during soldering and expose the metal substrate. Please note that the holes are too small for standard screw-in tripods. picture included. Accordingly, until I figure out how to mount them, I get 4 stars.
