Just a bit of advice, I’m planning on making a little development board to plug a mini straight into, for ease of programming. A little like the Nano one which you can buy off ebay (see photo). Although, not as complex, as in not a reset button and possibly not extra power rails, we’ll see.
I’m planning on power it up with a plug in psu, so I’ll get a female jack (if thats the correct name?). Should any resistors be put into place or capacitors? For anything other than input voltage. Anything incase there’s a spike in voltage, for protection.
On a separate note, for testing I was going to use either 2 or 3 AA NiMh batteries and directly connect to the RAW pin. Should a use a voltage regulator to maintain over 3.3V or just let the brown out function do it’s thing. Or increase the BOD fuses so it cuts out at say, 2.8V.
I looked for a tutorial but couldnt find anything.
