Waveshare ST-LINK/V2 (EN), STM Programmers & DebuggersDescription 1. The ST LINK V2 is an in circuit debugger and programmer for the STM8 and STM32 microcontroller families. The single wire interface module (SWIM) and JTAG serial wire debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board. 2. STM8 applications use the USB full speed interface to communicate with STMicroelectronics ST Visual Develop (STVD) or ST Visual Program (STVP)
Description1. The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families. The single wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board.
2. STM8 applications use the USB full speed interface to communicate with STMicroelectronics ST Visual Develop (STVD) or ST Visual Program (STVP) software.
3. STM32 applications use the USB full speed interface to communicate with Atollic, IAR, Keil or TASKING integrated development environments.
Key Features
1. 5V power supplied by a USB connector
2. USB 2.0 full speed compatible interface
3. USB standard A to mini B cable
4. SWIM specific features
5. 1.65 V to 5.5 V application voltage supported on SWIM interface
6. SWIM low-speed and high-speed modes supported
7. SWIM programming speed rate: 9.7 Kbytes/s in low speed and 12.8 Kbytes/s in high speed
8. SWIM cable for connection to the application via an ERNI standard vertical (ref: 284697 or 214017) or horizontal (ref: 214012) connector
9. SWIM cable for connection to the application via a pin header or a 2.54 mm pitch connector
10. JTAG specific features
11. 1.65 V to 3.6 V application voltage supported on the JTAG interface and 5 V tolerant inputs
12. JTAG cable for connection to a standard JTAG 20-pin pitch 2.54 mm connector
13. Direct firmware update feature supported (DFU)
14. Status LED which blinks during communication with the PC
15. Operating temperature 0 to 50 °C
Application Example
Connecting the PC and STM8/STM32 application board through ST-LINK/V2 to establish hardware connection
Connection with STM8 applications
The ST-LINK/V2 should be connected to the STM8 application via the SWIM cable. Two SWIM cables are delivered with the product:
- SWIM flat ribbon with a standard ERNI connector at one end and a 4-pin connector at the other end
- SWIM flat ribbon ended with a 4-pin, 2.54 mm, low-cost connector on two sides
Connection with STM32 applications
For STM32 developments the ST-LINK/V2 must be connected to the application using the standard 20-pin female-female JTAG flat ribbon provided.
ST-LINK/V2 Status
The LED labeled COM on top of the ST-LINK/V2 shows the ST-LINK/V2 status (whatever the connection type). When the:
1. LED is blinking RED: the first USB enumeration with the PC is taking place. If it keeps blinking RED, maybe the USB driver is NOT found.
2. LED is RED: communication between ST-LINK/V2 and the PC is established (end of enumeration).
3. LED is blinking GREEN/RED: data are being exchanged between the target and the PC.
4. LED is GREEN: the last communication has been successful.
5. LED is ORANGE: ST-LINK/V2 communication with the target has failed.

Great design!
Color: Higher Level-Navy A
This Joansan Dog Puzzle Toy is exactly what I was looking for. My little MinPin is a worker and he likes having a job to do. I purchased this to entertain him when rolling his treat ball all over the place isn't practical. This disc has a non slip bottom and it's actually fairly heavy. It doesn't slide easily. So my little worker usually ends up picking it up and transporting it to different locations throughout the house. Obviously, individual results will vary, depending on size, personality, and breed of the dog using it, but it's been great for my lil guy. He gets a little physical and mental exercise. It's sturdy enough to withstand his scratching and chewing. My big dog likes it too. The size is perfect for food oriented cats too. My cat is too lazy to work for his food though. So he wasn't interested in it.

This feeder will surely make your dogs work for their food.
Color: Higher Level-Navy A
I recently tried this slow feeder (I purchased 2 feeders) for my two Corgis (25 & 30 lbs.). Overall, it’s a well-constructed product and definitely slows down eating as intended. The design encourages dogs to work for their food, which helps with digestion and keeps them engaged.
That said, there are a couple of challenges I noticed. The kibble sometimes gets jammed in the sliding doors, which can make it harder for my pups to access the food. Also, the feeder doesn’t hold a large amount of kibble—I found myself needing to refill it 2–3 times per meal to accommodate both of my dogs. Finally, my pups had a tougher time reaching the kibble in the middle ring, which caused a bit of frustration.
Despite these issues, it’s sturdy, safe, and does the job of slowing down fast eaters. I think it could work especially well for smaller dogs or those who eat less at mealtime.

He loves it, what else is there to say!
Color: Green
My dog loves this ball. Originally we used it as it is designed and put treats inside it to knock out and keep him busy, now he just loves to throw it around and fling it by the pieces of fabric that come out. He is generally a toy destroyer so the fact that it is still arounds shows that it is strong and was for sure worth the buy. Would 100% recommend for any dog that likes to keep busy!

Pupper shakes with excitement when I take this out
Color: Green
This is a very good toy for a super busy pup but take it away after they find the treats or it's getting destroyed (the fleece) totally worth the money and the five minute prep time for a play session

Good for gentle dogs, not so much for chewers
Color: Green
My pup loves this and it definitely keeps him entertained, but the fleece ties are not the strongest so if you have a strong chewer be ware that it will not last too long (he's been playing with it for a day and we've lost 3 so far)
