Hi, I would like to use the PCA10000 dongle hardware and antenna design for my PCB, i got some questions: 1)I have just UART pin outs extra, I would like to reduce the cost and the complexity i want to go with 2 Layer PCB, What will be the drawback or advantage for 2 layer vs 4 layer PCB.
2)My PCB is larger than the PCA10000 Dongle so that ground area is bigger, does have a negative affect on the antenna or the matching circuit.
Thanks
