The KingST KQS3506-LA16100 is a USB-based, 16-channel logic analyzer with 100/50/25/12.5MHz sampling rate (at 2/4/8/16 enabled channels).
This is a clone of the Saleae Logic16.
See KingST KQS3506-LA16100/Info for more details (such as lsusb -vvv output) about the device.

Pinouts and connections:
I2C EEPROM:
The Microchip 24LC02B is connected to the Cypress FX2. The WP pin of the EEPROM can be jumpered to low or high, in order to write-protect it (or not). The address pins (A0-A2) are all connected to GND, which makes the I2C slave address of the EEPROM 0x50.
| A0 (GND) | 1- | O | -8 | VCC (3.3V) |
| A1 (GND) | 2- | -7 | WP (jumper W2) | |
| A2 (GND) | 3- | -6 | SCL (FX2 SCL) | |
| GND | 4- | -5 | SDA (FX2 SDA) |
CLPD:
The Altera EPM3032A JTAG pins are available on the J3 pin header.

JTAG header (CPLD):
The J3 pin header is a JTAG connector wired to the CPLD (it is not additionally wired to the FPGA in a JTAG chain). The pins are (from left to right):
| 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|
| TMS | TDI | TCK | TDO | GND | 3.3V |
