Review: Get this one - Worked great, just follow the Esoterical can bus guide to flash it and get a proper crimper. The RP2040 version is much easier to crimp.
Review: Works great till you let the smoke out. That was on me!!!! - I put this on my Voron 350mm I love the idea of looking at it at a glance to get the quick info. As far as its full functionality its more of a cute "option" for me. Look my tool head has a face. Looks cool in a dark room "My printer is watching you" Build is good just don't let the magic smoke out.

## Features

- High-Performance U2C: support CAN bus connection, long data transmission time, strong anti-noise ability, strong real-time performance and high reliability
- Specially Treated PCB Surface: Immersion gold process is adopted, with better color and luster. The crystal structure formed by immersion gold is easier to weld than other surface treatments, and can have better performance and ensure quality. The stress is easier to control, and the experience is better when using
- High Reliability: TYPE-C port ESD protection to prevent static electricity from damaging hardware, and supports firmware update for the motherboard through SWD or hardware DFU
- Adapter Board: There are many different forms of CAN interfaces on the board, which help to connect different boards. The CAN bus has a long transmission distance, and a large number of nodes can be mounted on it. one connection multiple
- Note: 12/24V and GND should not be reversed. When using CAN communication, you need to see which CAN node is used as a terminal. If it is a terminal, you must plug the jumper cap at the 120R position

## Questions & Answers

**Q: is this marketed towards women/girls?**
A: It;s marketed toward anyone who finds it appealing. She's got a hell of a rack so I think it's targeting men, too. I bought 2. Ill take a hot large chested chick holding a soldering iron over a duck any day.

I suggest being more secure in your masculinity, if you're a guy. If you're literally asking cause you want to gift it to a girl then yes, you can. You can gift it to a boy too. 

its 2022 FFS. Stop being so gender normative. Colors aren't what make a man or a woman.

**Q: So it does not have a power jack?**
A: Nope. It is powered by the very short (~4") USB cable. (or any other USB -> micro-USB cable). It does not appear to have a Vin pin, nor a 5V regulator, so it is not suitable for any power source higher than 5 volts.

### ⭐⭐⭐⭐⭐ Reduces Wires but Adds Complexity
*by D***5 on April 7, 2024*

Though it sounds great to be able to swap out hotend types, sensor types without dismantling the bunch of cable tracks, it does take a great deal of configuring, and can be confusing if you don't understand how it all talks. Bigtreetech has a great manual which you should read first before tearing into this to know it will be an undertaking. Once you follow their great instructions it will be rewarding as it will be easy to manage upgrades in the future. It is a great kit, well documented, frustrating and fun
