Add a second LED for 1.8V out
- I am concerned that the smallest voltage dropout voltage of our LED test (and the normal LED testing I searched online too) is 2V, which is bigger than the 1.8V so it would not be efficient through my research. Do you want me to still add it?
Change the colour of this title to match the colour of “GND”, “3V3”, etc.
Add test points for 1.8V and 3.3V and a GND test point as well. ✅
Look at the 48-17V buck schematic and see which TPs were used for the power and GND and use the exact same ones here ✅
Annotate schematic → label components ✅
- Click annotate schematics quietly and that’ll do it

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?

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 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.
