If you select the pin on the right that will be 3.3V and the one on the left will be 5v. If we choose the middle port as pictured above that will give us 1.8v.

With the LDO in place, now all we need to do to change the voltage on the USB to Serial Adapter is remove the jumper and connect the cable to one of the 3 ports. These are quite common from electronics stores but the time I didn’t have one so i cut one of the cables connecting a USB port to the motherboard in an old PC I had lying around. On the top of the adapter you can see I have used a piece of wire with a connector on it. Multimeter (optional) to test the voltage has been dropped to 1.8v.In Australia you can get them from Ja圜ar, I use this one.

“Helping Hands” (optional) Particularly useful is the magnifier with a light.Superglue to glue the LDO chip onto the serial connector.Small guage wire to solder the connections from the LDO to the serial adapter, something like speaker wire or USB wire from an old computer.Solder, I used a solder wire that was 60/40 alloy, 0.71mm diameter, 2.2% flux, 15 gram weight.I am in Australia so I picked mine up from Ja圜ar, doesn’t need to be expensive a basic one will do. 1.8v LDO Regulator (Low Dropout Voltage Regulator).I know the PL2303 chip will also work as I have seen others use that one. USB to Serial TTY running an FTDI chip FT232RL.I found it difficult to find a 1.8v USB to Serial and the ones I did find were expensive so I made one myself for under $10.

If you can find a 1.8v version they tend to be pretty expensive. This presents a problem because almost all the serial connectors you’ll find for sale run at 3.3 volts or 5 volts (due to the popularity of Arduino projects at the moment). The serial port you connect must run at this voltage or you risk damaging your Kindle’s board and components. The most important point to consider before you connect a serial cable to your Kindle is the voltage level the Kindle runs at, which is 1.8 volts. Whether that is something as simple as needing a new battery or a more complicated problem like file system corruption or firmware issues.Įven if you don’t have an immediate problem to fix, perhaps you are just curios to see what your Kindle does when it boots up or run some diagnostics on it to discover what state it is in. Access to the command line will give you valuable insight as to what errors are being reported and guidance as to what your most likely path to fixing your Kindle will be.
