• Put GND pins at the bottom like you did with the filtering caps ✅

• Is this going to be a firmware feature? As in will firmware be needed to “detect_antena”?

  • This is what I am understand from the datasheet, please correct me if I am wrong. Since we use the external antenna, we need to use the detect antenna to check if the antenna will be working or not in the long distance. And yes, this is a firmware feature.

• We can place TPs afterwards for this as we continue to work through it as we learn more about RF and antenas as required.

  • Still may potentially add external antenna

    • I think we have to add it and would you suggest where I should add the test point?

• Annotate schematic → label components

  • Click annotate schematics quietly and that’ll do it

• Can you explain and justify this 1kohm resistor here? After briefly checking datasheet, I am seeing mixed opinions on it depending on if there is a “rechargable battery” being used which I don’t think is applicable to us.

  • Ok , this one I am not sure too. Need to ask Billy about if we use “rechargable battery”I just ask Billy about it. First of all, the rechargeable battery is separated VCC to the voltage input (look at my new schematic). He just said that it is dependent on us whether we want to buy a rechargeable or not.
