[OT] Similar to OpenLog but faster?

Hello!
do you know any product similar to OpenLog but faster?

i.e. a UART to microSD FAT32 recorder, OpenLog would work but is limited to
115200 bps, I need at least 230400 bps for a projet and 921600 bps for another.

Even better, are there easy to use FAT32 libs for PIC32?

With kind regards,
Mario

Hi Mario according to the OpenLog hook-up guide:

baud - This command will open up a system menu allowing the user to enter a baud rate. Any baud rate between 300bps and 1Mbps is supported. The baud rate selection is immediate, and the OpenLog requires a power cycle for the settings to take effect. The baud rate is stored to EEPROM and is loaded every time OpenLog powers up. The default is 9600 8N1.

If you are connecting through a FTDI => USB then it is possible to use faster baud rates than the usual by spoofing the actual rate in the driver - FTDI have (had?) documentation on doing that. I have run FTDI devices up to 3 Mbps by re-assigning the 300 baud setting (who uses 300 baud?) It is a while since I did this so details are hazy but you need to modify the INF file.
