The Robomotic MiniLogic is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate.
It is a clone of the Saleae Logic.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See Robomotic MiniLogic/Info for more details (such as lsusb -vvv output) about the device.
Hardware
- Main chip: Cypress CY7C68013A-56PVXC (FX2LP) (datasheet)
- Octal 3-state non-inverting buffer/line-driver/line-receiver: 74HC244A (TODO: vendor?)
- 1A low-dropout voltage regulator (3.3V): Advanced Monolithic Systems AMS1117-3.3 (datasheet)
- 2K I2C serial EEPROM: 2x Microchip 24LC02BI (datasheet)
- 64K I2C serial EEPROM: Microchip 24LC64I (datasheet)

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