The Saleae Logic clone is USB-based logic analyzer with 8-channel and up to 24MHz sample-rate.
Looks like a clone of the Saleae Logic. It's USB-device ID is: 0925:3881
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
Hardware
- Main chip: Cypress CY7C68013A-56LTXC (FX2)

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