Subject: Another PL2303
Date: Sun, 6 Mar 2022 17:52:58 +0100	[thread overview]
Message-ID: <165de6a0-43e9-092c-2916-66b115c7fbf4@gmail.com> (raw)

Hi,

I recently bought a serial console adapter with PL2303. After a quick 
search I discovered that there have been problems with different 
versions of this chip so I include some info about mine.

Thanks in advance

Matyáš
