Overclock Pogoplug V4 and Mobile

I get it - a Pogo E02 is the power source for the three wires that go to the serial pins on a v4/SATA/USB3 model, which v4 Mobile lacks. Ahhh.

syong excuse me, I'm newb in these areas and probably not all there anyway LOL And born the Chinese year of the Snake so I'm probably best to let others monkey around (oh! bah doom shhh).

Great stuff though, thanks for inspiring us all!

@Joey, Those wires go to the serial port of my pogo v4. I use three pins to connect serial ports: ground pin, input pin and output pin. Just make sure input pin of one serial port connects to the output pin of the other serial port.

@bodhi, You are right. Since the pin is the input, connecting it to 3.3v will not fry it. Actually the unused pin out of a 4-pin serial port is 3.3v. You can use a jumper connecting it to the input pin if you have the access, so no need for USB2TTL adaptor. Connecting input pin to 3.3v will not affect the serial console once you disconnect it after booting and possibly a resetting.

I think it will be OK to leave the jumper in while connecting serial console. But serial console input might not work.

In that case, the jumper should be a pull-up resistor. This is because if you connect serial ports with a jumper inside, the 3.3v will short to the output pin of the other serial port.

Thanks for that reminder syong. Still sounds doable even for soldering-challenge people like me!

But l think I will leave the jumper in. And take it out when serial console is needed.

The jumper is supposed to be temporary. Please be careful -- mishandling could be a fire hazard.

Got it. Permanent mod will be the resistor soldered to the pins.

Correction! Just found the pin to be pulled up is the TX instead of RX. My excuse is my USB2UART is mislabeled.

So shorting to 3.3v is not recommended although it might work. This is real life, not ideal as what I thought.

Hope you did not fry anything. I didn't. :)

Ah, that would happen when using both CP2xxx (not crossed) vs PL3xxx (TX/RX crossed) ! No I did not fry anything ... yet :)
