@ -69,7 +69,7 @@ Perhaps the two 'nc' pins go to a different chip.
When using a custom driver (and not ScanaStudio), my SQ50 seems to happily sample at 200 MHz when specified in the settings, even though it is not marketed to be able to do this.
However, unlike the SQ200, it has much less SRAM for storing samples. This can be fixed by populating the 3 empty pads intended for ISSI chips. Once you've finished the physical part of the upgrade, you can change the device type by running [this script](https://git.lain.faith/BLAHAJ/sq50-re/src/branch/main/change_device_type.py), this will also make the upgrade work in ScanaStudio! (**NOTE**: do take a backup of your FTDI config EEPROM first, though.)

(**NOTE**: do take a backup of your FTDI config EEPROM first, though.) I don't know if ScanaStudio sends statistics about device serial numbers (to detect possible counterfeiting), so I've made the script be able to change or randomize device serial when requested. I also run ScanaStudio in a [firejail](https://wiki.archlinux.org/title/Firejail) to disallow network access.
You can get these ISSI SRAM chips here:
