The VKTEK is a fairly standard Cypress FX2 based 8 channel 24 MHz logic analyzer, it is most similar to the ARMFLY_Mini-Logic and MCU123_USBee_AX_Pro_clone devices, though has differences from both of them (SMD LEDs, QFN package unlike MCU123, transceiver IC unlike ARMFLY).
sigrok uses the open-source fx2lafw firmware for this logic analyzer.
The device uses USB\VID_0925&PID_3881 so is indistinguishable from a Saleae_Logic device
Mine was purchased from AliExpress and arrived in 6 days.
