Moding Card Reader for 5V Power

[TallKey]

Tony, you raise good questions. See this thread. Same link as post #1.

CR runs 4.4V to 5.5V, per CR service manual, p4-4 and can pull voltage down to 3.4V (as I read the SM).

Net is this:
Power 41 with external power.
Repair a broken CR.
While repairing broken CR perform what is suggested in the above post.

Below is the meat and potato part of the above link:
As long as you have a USB port handy (any stable power source for that matter)

Standard USB cable
- Cut the cable to an appropriate length.
- Identify the +ve and -ve wires.
- Solder the Positive wire to BAT
- Solder the Negative wire to GND

Disinterested in sacrificing a 41 module or squander a 41 port. That is ought to be clear from post #1.
