Well that's certainly true! It's not the answer i was looking for, but i think that deserves something - call it the "smartypants" prizecanadianavenger wrote:There's a watchdog in the AVR... so it's invisible

Never even considered it, as it's a bit... limited.
Its timeout granularity is too coarse, the timeouts are heavily dependent on the input voltage (it's just an RC circuit, basically), and most importantly, enabling and disabling it can be done in software only, which kinda beats the purpose (having it enabled all the time is inconvenient, so you need to enable it only when you really do need it... and what if the software crashes before you can enable it?).

Close but no cigar - that's the 3.3V regulator for SD card ( 3x3mm DFN-6)

Otherwise, no clue, LOL
