In the custom mechanical keyboard, the biggest problem and choice is actually PCB. Among them, Korean PCB is the most popular, with its special thinking and firmware functions. Of course, due to purchase and cost reasons, the price of playing is relatively expensive, among which FaceU is the most popular. According to the open-source estimate, the replica FaceU came into being.

The original FaceU is made in South Korea and has two versions, V0.1 and V0.2. Due to the thickness, V0.1 is the most popular. As explained here, FaceU is divided into 1.2mm and 1.6mm in thickness according to different versions. Among them, 1.2mm is the most popular because of its wonderful rebound.

Due to the time, the welding is directly completed and presented to everyone. It should be noted that the 1.2mm thick version of FaceU should be used, and it is better to match with the axle body with no or weak sections such as black tea, and no steel plate should be used. At present, due to the supply of axle body, the price of pentapod axle body used when steel plate is not used is slightly higher.

The color of the original FaceU PCB is green, and the color of the duplicate can be adjusted according to the needs, which is also a highlight of domestic products. Invite friends in the circle to help with the processing. The solder joints are perfect.

The biggest feature of the 1.2mm thick FaceU is of course the bending of the PCB. Don't underestimate this bending, which brings about wonderful hand feel.

If it is used together, the FMJ I have is more suitable. For the 1.2mm FaceU, to experience the subtle springback of PCB, the requirement for the shell is that there is no corresponding stiffener to give the PCB a certain springback space.

In actual effect, FaceU is designed for the lower light point and supports five LED modes, which are 1: switch LED 2: breath lamp 3: normally on 4: no typing no lighting up The faster you type, the brighter you will be 5: light up when you don't type, and fade down slowly when you type. The third effect is opposite to the third effect. Other details include various firmware rewriting support and key position support.

Of course, the mechanical keyboard still needs a good hand feel. After the foreshadowing above, it is obvious that what I want to say is that FaceU has a good hand feel. Since the FMJ has no stiffener against the PCB, and the thickness of the PCB is 1.2mm, it has a special flavor when paired with the red axis. The wonderful rebound feeling given by the PCB is quite surprising. Unlike Cherry, FaceU is more flexible, so it will not be tiring to use it for a long time.

Of course, the more important problem is the cost. Although the cost of copying has been reduced to about 160 yuan compared with the original factory FaceU, which cost about 450 yuan, the cost of pure materials has been more than 600 yuan with the shaft body. Even the charm of a custom keyboard is a little daunting. But there is really nothing to replace the wonderful feel of FaceU.
