[Solicitation Order] t12 soldering iron

Introduction: T12 soldering iron

The t12 soldering station control board has just the effect of 60-450° adjustable, high-speed heating.
LHW-createskyblue has made an excellent upgrade to the user interface, which you can choose to install. It has the following features:

* Beautify the detail page and add a power bar
* The menu has icons
* Better scroll animation
* Get rid of the U8g graphics library and use the ArduBoy graphics library (Lite) to increase the frame rate and reduce memory usage to make graphics possible
* Add flip display settings to adapt to different people's habits
* Screen saver
* English, Chinese and Japanese language pack
* System password
* Better digital input experience
* Chip overheating and low voltage alarm

Polytechnic University_PCB Commemorative Card

Introduction: PCB card of Xi'an University of Science and Technology College of Science and Technology

The PCB commemorative card of Xi'an University of Technology College of Science and Technology
 
shows the college's motto and design plan on the front, and functional modules and three USB2.0 expansion interfaces on the back. One driver-free option is 150Mps speed WIFI or 10m/s speed 32G storage U disk. Due to the flatness of the card surface and process limitations, only double-layer boards can be drawn. The WIFI uses module 7601B module and vinyl USB flash drive. The next batch of four-layer boards will be produced in small batches, using VL812 to control USB3.0 high-speed HUB, and IS903 to control 64G high-speed USB3.0 U disk.
 
There are painted basketball, football, badminton, and tennis courts, which you can pick up on demand. The project needs to be opened in an editor to see it. When I look at the project here, it seems to be blank, but in fact it is all drawn. Only one welding option can be selected between the WIFI module and the USB flash drive. The selection pad is reserved and the default is the WIFI module. If you do not solder the U disk, do not short-circuit the pad. Signal reflection will seriously affect the stability and cause unrecognition. If both are soldered together, it will not be recognized. You can change this yourself and just pull the USB over.
