Ifixit has disassembled the three little guys one by one. Let's take a look at the keyboard first.
The three dimensions of magic keyboard are 10.89 Ã four point five two Ã 0.43 in. (276.6 in.) Ã one hundred and fourteen point eight Ã 10.9 mm), supporting Bluetooth wireless connection, built-in lithium-ion rechargeable battery, lightning interface for charging and pairing.
New model a1644.
Compared with the third generation wireless keyboard, the new keyboard has been redesigned inside and outside. The key layout is from the 2015 MacBook notebook, including full-size left and right arrow keys and function keys, and the key range is shorter.
The design of the built-in battery no longer needs the battery compartment which used to occupy a lot of space. The overall height is greatly reduced and the operation is more comfortable.
It goes well with the new touch pad.
Is there a screw under the rubber pad? NOã The keyboard shell is buckled together without using screws, which is naturally a cleaner appearance.
Ifixit's housekeeping kit.
There is a gap between the plastic bottom shell and the aluminum frame, but it is very narrow, so we have to use a variety of tools.
Obviously, I feel that the internal glue is bonded very firmly. I can only pry it off while heating.
The bottom panel finally came down.
You can already see the battery and circuit board.
Disconnect the battery connector.
The battery itself is not fixed with glue. I'm relieved.
The battery specification is 793mah and 3.0whr. It can be used for several months for a single charge.
Disconnect the lightning cable.
The circuit board is fixed with a small screw. It is a standard T3, not dedicated to apple.
All right, come down.
Red: Broadcom bcm20733 Bluetooth 3.0 single chip solution
Orange: stm32f103vb 72mhz 32-bit RISC Cortex-M3 microcontroller of Italian French semiconductor
Yellow: NXP 1608a1 charging controller
Green: Texas Instruments bq24250c single input I2C / independent switching mode lithium ion charger
The back of the motherboard is empty.
Layer after layer.
There are also two small screws for lightning interface.
The lightning interface has finally come down.
Key cap, new shear fork structure.
Take a group photo as a souvenir. The disassembly and maintenance index is 3. It's difficult to serve.
