I want to do the most simple node using a RAK811.
Seing the chematics i see it´s necessary the following circuit to ( for 50ohm) connect the lora Antenna.
To simplify things, you’ll be good if you minimize the length of trace from the RF out of RAK811 to your antenna connector. Just maintain the PI network (in case your’ll need it) and just put 0ohm. 0402 should be a good choice to minimize the size and still solderable by hand.
