The '''MCU123 Saleae Logic clone''' is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate.

It is a clone of the [[Saleae Logic]]. It's also ''very'' similar to the [[MCU123 USBee AX Pro clone]] minus the different USB vendor/device IDs.

In sigrok, we use the open-source [[fx2lafw]] firmware for this logic analyzer.

See [[MCU123 Saleae Logic clone/Info]] for more detailed information on the device.
