anyone need POGO cable for HP 20b/30b, HP 15C LE?

[hojeongko]

I found a way to get a POGO cable that works for the HP 20b/30b, HP 12c+ (2008-2005), HP-12c 30th, and HP 15c LE.

Here
6pin pogo connector
erase and reset button
Anyone can perform flashing using .

Necessary items
1. POGO cable(the calculator store), POST 2015 HP 12c, HP 15c CE
2. USB A extend cord.
3. PL2303HX USB to TTL RS232.
4. Soldering tools.

When you remove the case of the PL2303HX, you will find the board inside.
Use a soldering iron to separate the cable.

Cut the USB A extend cord.
Only use the USB A (female) part.
Peel off the wire and reattach it to the board prepared above.
When connecting lines, you must be aware of TX and RX.

When first disconnecting a wire from the board, check the color of the connecting wire carefully.
Afterwards, solder the prepared USB A cable again, but this time, solder it in a different color from the existing one. That is, connect the Tx of the board and the Rx of USB, and connect the Rx of the board to the Tx of USB A. Vcc is not used. GND connects to GND in the same way.

If you've done this, your work is done.
If you connect the newly made product with the pogo cable shown in item 1, it becomes a flashing cable for voyager using ARM versions prior to 2015.

When the gender is separated, it becomes a flashing cable for arm-using voyagers from 2015 or later to suit existing uses.
