The Braintechnology USB Interface V2.x is a Cypress FX2 eval board, which can be used as USB-based, 16-channel logic analyzer with up to 24MHz sampling rate.

There are various revisions of the hardware, e.g. V2.5, V2.6, and V2.7.

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

See Braintechnology USB Interface V2.x/Info for some more details (such as lsusb -vvv output) on the device.


  • Main chip: Cypress CY7C68013A-56PVXC (FX2LP)
  • 64kB I2C EEPROM: Microchip 24LC641
  • Low-dropout voltage regulator: ST LD33
  • Crystal: 24MHz
  • ?: PDEI



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