The VKTEK is a fairly standard Cypress FX2 based 8 channel 24 MHz logic analyzer, it is most similar to the ARMFLY_Mini-Logic device, though using SMD LEDs and a transceiver IC instead of discrete SMD diodes for ESD protection.

Mine was purchased from AliExpress, and arrived in 6 days. https://aliexpress.com/item/24MHz-8-Channel-Logic-Analyzer/32814170174.html

The VKTECH clone is a USB-based, 8-channel logic analyzer (and signal generator) with up to 24MHz sampling rate.

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
