Re: USB Comms Adapter

the EOL'd HXA is the HX (rev A), the HXD on that page is "HX (rev D)" if you don't need the crystal to operate it, and PIN 25 => GND , then -hopefully- is the D variant : https://www.compatel.hu/images/Controller/PL-2303HX_Documents_Application%20Notes.pdf Prolific had issues with those co...

Re: USB Comms Adapter

Guys I am not exactly into the M$ driver certification, but the whole thing is a bit complex as it depends by the vendor (vendor ID) driver signing with the M$. in the case of Prolific (PL2303): they suggest the use of their PL-2303GC as you can see on their site https://www.prolific.com.tw/US/ShowP...

Re: Backlit Keyboard

yeap I know what you mean, what I wanted to say is you probably need to replace the "whole" keypad area, if you disassemble old mobiles that have keypads you will see the keycaps are being seated on a white (milky) "matrix" this helps the light to be spread around, the keycaps th...
