The Braintechnology USB-LPS is a Cypress FX2 based 16-channel, 24MHz, USB-based logic analyzer and signal/pattern generator.

In sigrok, the open-source fx2lafw firmware and driver is used for this device.

See Braintechnology USB-LPS/Info for some more details (such as lsusb -v output) on the device.


  • Main chip: Cypress CY7C68013A-56PVXC (FX2LP)
  • I²C EEPROM: Atmel ATtiny13-20SU
  • 3.3V voltage regulator: LD33
  • Crystal: 24MHz



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

However, for those interested in this, see our old vendor protocol docs.
