I’m working with Seed Grove Lora E5 module, for now I’d like to create my own board inspired by Grove module. I’ve looked the schematic pdf but I have a question.
On the PDF on the RFIO pin before the antenna we have 2 condensators and 1 resistor. C7 and C8 doesn’t have value, and R8 vamue is 0R. Why? There is a way to calcultate this ?
