The first two are the ones you need

• CH341SER.EXE – self installing archive with USB to serial driver. Direct Link : ch341.exe
• CH341PAR.EXE – self installing archive with multiprotocol interface driver (this one is for the programmer mode) : Direct Link : ch341.exe
• CH341SER.ZIP – archive containing driver files and serial API and library (you don’t need specific API for standard serial port, but it contains some special functions to get IC version etc.)
• CH341PAR.ZIP – archive containing driver files for interface mode and API (header and library to access the device and use any protocol you want).
• CH341PAR_LINUX.ZIP – archive containing Linux driver source code and Linux API
• CH341SER_LINUX.ZIP – Linux driver source code for serial port (don’t need this one, it’s already included in kernels)
• CH341EVT.ZIP – some source code and tools written to be used with an evaluation board (may be useful for programming software that can access this device)
• CH341DS1.PDF – datasheet, in Chinese
• CH341DS2.PDF – some additional info and API documentation, in Chinese
• CH341DP.ZIP – contains an ISP programming tool?
• CH341DPS.ZIP – probably similar to the above, but requires login to download
