- Cons
- Expensive and Wasteful
- Basically scrapping the rest of the Arduino
- Expensive and Wasteful
- Pros
- Add ISP pins to VEGA for uploading the Bootloader / Sketches
- Pros
- Adds configurability for later on
- Cons
- Relatively large to have 6 pins added (relative to the board size)
- Additional routing complexity
- Not ideal pins required
- Not ideal pins required
- Pros
- Make a jig to burn the bootloader onto blank uCs.
- Pros
- Not too difficult
- Reusable
- More generic
- Cons
- Requires another board
- Should be soldered protoboard, not custom PCB
- Additional solder cycle for uC
- Jig could fail over time
- Solder pads
- May not be too big of an issue considering the low count being made
- Requires another board
- Pros
