Doubt to pass code Lilypad.

I can use the TTL PL2303HX for pass the code for Lilypad?

Thankyou.

you should be able to, keep in mind that many of the cheap clones may have driver issues, and observe the pin configuration.

yes, i know, but the doubt is if the TTL PL2303HX can pass the code or only the FTDI232?

You mean you've tried but you haven't managed ?

SandroMesquita's module:

If you already own that module, it will work fine. However, I strongly recommend against buying this particular module because it's very inferior to other modules that are similarly priced. The biggest problem with this module is that it does not have the DTR pin broken out. The DTR pin is used to automatically reset Arduino boards at just the right time during the upload. When you don't have a DTR pin, you will need to manually reset the board at the correct time. To know the correct time, watch the black console window at the bottom of the Arduino IDE window until you see something like this appear:

Sketch uses 4246 bytes (13%) of program storage space. Maximum is 30720 bytes.
Global variables use 204 bytes (9%) of dynamic memory, leaving 1844 bytes for local variables. Maximum is 2048 bytes.

As soon as you see that, press and release the reset button.

I recommend only buying USB to TTL serial modules that use the standard "FTDI header" pinout:

  • DTR or RTS
  • RX
  • TX
  • VCC
  • CTS
  • GND

That will allow you to plug the adapter right in to an Arduino Pro Mini, or many other boards that use this standard pinout. If you get an adapter with a non-standard pinout, you would need to use a mess of jumper wires to adapt it to the standard pinout. They don't need to have an FTDI chip, CH340, PL2303, CP2102, etc. will work too.

This is the module I use:

The Chinese sell them on eBay for $0.74 USD w/ free shipping. The FT232 chips on them are counterfeit, but they work just fine.

As long as the DTR or RTS pin is available, any ttl serial adapter for which you have working drivers installed will work. I use ch340g's because they are stupid cheap.

As soon as you see that, press and release the reset button.

I actually hold the button down until i see that. I have several of those modules, All 'fake' prolific, which means i have to use an older driver (since the newer one tests for a genuine Prolific chip) like this which works on windows 8.1 but on windows 10 this driver will get automatically updated to the newer one. The truth is that it is a trip and that i now upload to my pro-mini's and ESP-01's using an Uno i have, which actually works a lot easier.

No. no. I am wondering if it's possible. Because in my City only have that.

Very good your comments. Thankyou.

I think that question has been answered (providing it is a genuine prolific or you can install another driver that works)

Thank you for the tip.

I 'm using the Arduino one.
