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.

Protocol

Since we use the open-source fx2lafw firmware for this device, we don't need to know the protocol.
