These things are great. I have undertaken the task of writing a driver for them myself. I intend on integrating the actual chips and required circuitry into my own pcb designs which is why I got these to practice on.
It is sensitive to electronic noise between it and an Arduino, I had to wrap the MOSI and MISO wires the ground wire for it to work. I have heard using short wires will also cut down the electronic noise.
100 feet away from my receiving unit. 3 walls total. I'm using the lowest power setting (setPALevel(0)). You have to have a very good power supply for the units to get the most of them.
Promptly shipped, well packaged, and 100 percent functional meeting all requirements. Nice job! I will be back for more.
Great product, just as described.
Thanks. Is very good.
Item works as described
Product was fine but vendor sends endless nagging emails about rating and new offerings with no way to unsubscribe.
Solid and handy. Love the antenae
Happy customer !
