v2 onboard hardware components
some fun v2 onboard hardware components are shown in the image below.
my favorite thing to play with so far are the 3 watchdogs:
- 9331 watches the 2560 and can reboot the 2560
- 2560 watches the 9331 and can reboot the 9331
- an external mpu supervisory circuit sp703spn watches both the 9331 and 2560 and can power cycle the entire board through the mosfet switch
