SparkFun Serial Basic Breakout - CH340G (Micro USB)The SparkFun Serial Basic Breakout is an easy to use USB to Serial adapter based on the CH340G IC from WCH. It works with 5V and 3. 3V systems and should auto install on most operating systems without the need for additional drivers. The Serial Basic uses the CH340G IC to quickly and easily convert serial signals to USB. It's a great lower cost alternative to the extremely popular FTDI Basic. The pinout of the Serial Basic mimics the common DTR RX TX

The SparkFun Serial Basic Breakout is an easy-to-use USB-to-Serial adapter based on the CH340G IC from WCH. It works with 5V and 3.3V systems and should auto install on most operating systems without the need for additional drivers. The Serial Basic uses the CH340G IC to quickly and easily convert serial signals to USB. It's a great lower-cost alternative to the extremely popular FTDI Basic.

The pinout of the Serial Basic mimics the common DTR/RX/TX/VCC/CTS/GND pinout found on hundreds of FTDI-to-USB derivatives. It can also be used as a general serial device for debugging (such as with a GPS module). There is a jumper on the rear of the board that controls the output voltage on the VCC pin. By default, the board outputs 3.3V and has 3.3V signals. Changing this jumper to 5V will cause the board to output 5V on the VCC pin with 5V signals.

Make your Cappuccinos!
Color: White
I purchased this after a trip to France. I drank a lot of cafe cremes, pretty much like a cappuccino, and decided I need it in my like every day. Easy to use. Didn’t come with instructions but I was able to figure it out. Takes a little time but works well for what I want to achieve. Love the glass pitcher. Doesn’t spill when pouring. It’s very quiet while frothing super easy to clean. I love it!

Great frother
Color: Matte Black
It makes a great milk froth and heats well. One thing however, in spite of respecting the line limit it spills out and you have to clean the whole thing. So don’t fill it up to the line limit.

Thick foam for Cappuccinos
Color: White-Stainless, Color: White-Stainless
Comes with sevaral options including thin and thick foam, hot milk and cold foam. I used the thick foam for cappuccinos and I was impressed by the consistency. Not so much noise and easy to clean. The frother tools come off easily for cleaning the pitcher.

Very slow--5+ minutes to froth and warm milk
Color: White-Stainless
Pros-- Makes nice froth and warms the milk. Both froth settings produce the same kind of froth. it's relatively easy to clean-- usually just a strong rinse will do. It does fine in the dishwasher too. The noise level isn't bad. Cons--it takes between five and six minutes to froth milk. It is very slow. I can froth latte art milk on my espresso maker in less than a minute, by comparison. The forth it produces is too thick to make any kind of latte art.

Quality
Color: White-Stainless
What really impressed me is how fast it works—in just a couple of minutes, I have hot, creamy milk with thick, rich foam. The texture comes out smooth and fluffy, just like a coffee shop. It’s super easy to use, and cleaning it is quick too. I’ve used it for lattes, cappuccinos, and even hot chocolate, and it works perfectly every time. Definitely worth it if you want something quick, easy, and makes great foam in large amounts
