Since Apple released the iPad Pro, the discussion about the new generation of super large iPad Pro has never stopped Apple Pencil It was pushed to the top of the wave for a while, and many people think that iPad Pro& Apple Pencil It is a bold innovation, and some people think that the combination of oversize+hand-painted pen completely betrays Jobs' teachings. Yesterday, we brought you the hands-on evaluation of iPad Pro Today, let's take a look at the best partner of iPad Pro—— Apple Pencil What is the magic of this high-tech "hand-painted pen".
Let's take a look at the parameters of Apple Pencil
Bluetooth 4.1
When using Apple Pencil, the screen scanning speed is twice as fast as using fingers
Up to 12 hours of usage
175 mm (L) x 8.9mm (D)
Lightning charging interface
Although the controversy over iPad Pro and Apple Pencil has never stopped, it has to be said that when they are combined, it is very convenient to write, draw, and mark. The large display area is very obvious for the improvement of visual experience.
At present, there are many stylus for iPad or Surface on the market. Let's compare them. The first one is the Microsoft Surface Pen, from the Surface Pro 4.
The second is one of the best hand drawn pens on the iPad at present, the iPad Pencil of FiftyThree.
Similar to Apple Pencil, the FiftyThree iPad Pencil has a built-in circuit structure that can support the Paper application launched by FiftyThree itself.
Apple provides installation tips for accessories in the packaging box, including a Lightning to Lightning adapter, which can be charged with an ordinary Apple charger without plugging it into the iPad.
The protective cover of Lightning interface is fixed with a magnet. Although the suction is good, it may still be lost.
The Lightning interface shows the Apple Pencil model: A1603。
The pen head of Apple Pencil can be disassembled. Let's take it down first.
There is a small metal device hidden in the pen tip. This small thing may be a small transmitter, which is used to identify the angle of the pen tip and the direction of pen moving.
After studying the structure of Apple Pencil, we decided to disassemble the Lightning interface and heat it first to soften the glue.
Next, we will slowly pull out the Lightning connector. The joint is bonded by a large amount of glue, which is very difficult to disassemble.
Finally, we removed the connector at the cost of damaging the flexible cable
After carefully observing the structure of the pen body, no more simple disassembly method was found, so the pen body had to be divided by violence.
The "pen core" can be taken out after the whole shell is cut.
We can take a close look at the refill, which is actually a metal shell.
There is a triangular screw on the pen core. We use a special screwdriver to unscrew it.
After some cutting, we finally pried the refill open.
It is composed of circuit board, battery and antenna, which is different from the common pressure sensitive pen with graphite pen core.
This pen uses a 3.82V 86mAh battery with very small capacity.
We separate the antenna, circuit and battery one by one. This little black and yellow thing is an antenna. The small integrated circuit connected to the battery is the connecting cable between the Lightning connector, the battery and the circuit board, which plays the role of charging and data transmission at the same time.
This circuit board is the brain of Apple Pencil, and all functions are realized by this circuit. This circuit board is very unique in design. It is folded and connected by two flat wires.
After unfolding this circuit board, we can finally have a look at it. Although this circuit board is really a sparrow, we can see the chips on the front:
There is also a chip on the reverse side:
After analyzing the circuit, let's take a look at Apple Pencil's unique nib. In order to remove the nib, we have completely disassembled the refill violently.
After completely peeling off the pen core shell, we finally separated the pen tip. This circuit board is one of the smallest we have ever seen.
The structure of the pen tip is complex, which is composed of the pen tip, pressure sensor and circuit board. The pressure sensor is connected to the circuit board through three contacts. We speculate that the pen tip is connected to the pressure sensor, and there is a certain expansion range between the two, so the pressure sensor can recognize the force of writing. After removing the circuit board, we can see that the chip model in the red box is 8529043 343S00008-A1.
Well, we have finished the disassembly today. The old rule is to give a family photo at the end. Like other Apple devices, iFixit only gives Apple Pencil 1 point for maintenance (10 points is the easiest to maintain). The structure of Apple Pencil is complicated after it contains the battery, circuit board, pen tip and other devices in the small pen body, and it is obviously difficult to repair when damaged. Fortunately, the pen tip has a replaceable design, which can be replaced when worn.
