good price, cables were not completely separated
Cables are probably made by peeling individual wires of a ribbon cable.
Red and black cables came completely separated.
Yellow, green and blue wires were bounded together to 3 wire cables.
There were 20 red, 20 yellow and 20 three-color cables, totally 100 wires.

This is NOT Stlink V2. It is STC Auto Programmer USB-TTL
5 personnes sur 5 ont jugé cet avis utile. Actually the product description was misleading. They call the product ST-Link V2 programming unit, and have pictures of 2 different products, One with 6 ST-Link V2 and another one with single STC Auto programmer.
I ordered 2 pieces and I got the STC Auto programmer.
I tried one of the pieces and while connecting it to USB cable it's metal cover has slided off. So you have to push on the plastic 2x5 connector, not the cover.
It is a serial converter with 3.3V data lines. It can program some microcontrollers, but It doesn't function as ST-LinkV2 and cannot do SWD programming.
It seems that it is ch341 serial converter and has different USB PID, VID than an stlink i already had before.
Identification of this product in linux:
$dmesg | tail

works, has a display with colors, female pin header has small height
I fitted this board on Raspberry 3 model b+ just to test it.
But the height of female pin header is small and didn't fully slide into rpi3 male pin header and wiggles around when buttons are pressed, but it wasn't designed for this board anyway.
This board has M3 holes and came with brass spacers, that were smaller than M3 and probably would wiggle.
To get the display working with RPI3 i ran
sudo raspi-config
and enabled SPI interface.
downloaded repo driver-ST7735S from user michal037 from github
changed a line that initializes display to:
myDisplay = lcdst_init(40000000, 10, 6, 2); // worked on rpi 3 model b+
10 6 2 are pins numbered by standard wiringpi numbering
then ran command:
make compile
./lcdtest
A colored line drawing appeared on screen.
To test buttons and joystick i enabled pullups from command line:
gpio mode 21 up # joystick left, defaultly wasn't needed
gpio mode 22 up # joystick up, defaultly wasn't needed
gpio mode 23 up # press joystick
gpio mode 24 up # joystick down
gpio mode 25 up # joystick right
gpio mode 27 up # upper left button
gpio mode 28 up # middle left button
gpio mode 29 up # lower left button
(again pin numbers in commands were standard wiringpi numbers)
then i ran a command that shows input pin values and pressed some buttons:
watch -n 0.3 gpio readall
buttons are active low and need pullups.
