Comparison: Tile Mate, Galaxy SmartTag, Apple AirTag and American quarter. AirTag is 1.5 times thicker than Tile, SmartTag is 2 times thicker than Tile.
Let’s look inside the AirTag with X-ray vision, and then, using a vice and a screwdriver, we will disassemble the case and admire the electronics.

Replaceable battery, which is rare for Apple products:
AirTags and SmartTags use 3 volt CR2032, 0.66 Wh (20mm). Tile is a smaller CR1632 with a capacity of 0.39 Wh (16 mm).
Tile and SmartTag can be opened with a screwdriver and a heat gun, AirTags required a vise.
AirTags housing is a speaker.
No hole to hang on your keychain? Do it yourself:
After the operation, the sound volume was not affected.
Wedeo to help you find a safe place to drill:
On the first side of the AirTag motherboard is the Bosch Sensortec BMA28x 3-axis accelerometer, which can also be seen in other Apple products, the battery contacts and the voice coil solder points, which work with a magnet.
On the other side:
Apple U1 Ultra Wideband Transceiver
Nordic Semiconductor nRF52832 Bluetooth Low Energy SoC with NFC Controller
GigaDevice GD25LE32D 32MB Serial NOR flash
Maxim Integrated MAX98357B Class AB Digital Audio Amplifier
Texas Instruments TLV9001 1 MHz Rail-to-Rail I / O Operational Amplifier
ON Semiconductor FPF2487 overvoltage protection load switch
DC / DC Step Down Converter, 300 mA Texas Instruments TPS62746
Most likely ON Semiconductor DC-DC converter
Probably Texas Instruments DC-DC converter
AirTag does not look like a “first version”, the device was worked on for a long time
Apple deviated from its principles and made a replaceable battery
There is no convenient keyhole, but it can be drilled at your own risk
The privacy question is open: “Can I turn off the speaker and use AirTag for tracking?”
