Re: Brownout reset general cause?

I removed the 7805 and that results in 4.98V when the board is completely empty.

I took a closer look at the drivers

• 5V - GND driver 1 alone = 13.7 ohm
• 5V - GND driver 2 alone = 9.7 k ohm
• 5V - GND driver 3 alone = 0.47 k ohm
• 5V - GND driver 4 alone = 1.5 k ohm

I have no reference knowledge but that seems high

Also when I measure the 5V - GND empty board get 24.2 k ohm,
and contrary to my expectation that high resistance driver would increase overall resistance on the board I got these results.

• 5V - GND board with driver 3 = 40 ohm
• 5V - GND board with driver 1 = 10 ohm

Just interpreting the difference in Voltage when the empty board gives 4.98V and the lowest resistance driver (#3) on the board gives mit 4.85V, and the highest (#1) 4.3V, does that mean the drivers are the bad guys here?
