“Audiotop” is hidden and exquisite: Khadas Tea magnetic decoding otpsus disassembly report
Khadas TEA is a thin decoding amp, which has magnetic suction function, which can fit on the back of the phone to unlock the new experience. TEA has a built -in large -capacity battery. In addition to the power supply purposes in the Bluetooth mode, it can also be used for wired mode, which can break through the power limit of the iPhone data port. In the actual test, TEA’s audio indicators have good results, and the audio quality is also high during high -definition Bluetooth encoding transmission, and it is comparable to the wired mode.
The appearance of TEA is simple, with large -scale glass on both sides.

Khadas logo battery, 1160mAh
Circuit board A side, less components
Two BTB connectors, one of which is not running to the battery, and the other should be to the keys.
Separate BTB plug
Remove the circuit board fixed screw
The circuit board is taken out of the cavity. PCB is cut into a rounded corner, with polishing and polishing on the side
Bluetooth RF line
At a glimpse of the circuit board B, the RF line was stored on the PCB.
Take off the metal buckle and pull out the RF plug
Completely separated the circuit board. Most components are distributed on the B side.

USB audio channel part
Core: ES9281ac Pro
This is the ALL In One DAC chip of ESS. It has complete functions and powerful indicators. It is widely used in portable decoders.
On the right is the otopal chip.
Bluetooth wireless audio channel part
Core: Qualcomm QCC5125 Bluetooth SOC, supports two high -definition codes: LDAC and APTX HD, low delayed audio.
This chip is more common in the high -end TWS headset.

ES9281ac Pro actually has a built -in amp module, but external otals can get higher power limit.
RT6863D is very common. Due to good performance, it is almost the standard earlier of small tail decoding.
There are 4 crystals in TEA, two of which are NDK
2 silicon wheat, distributed on both sides of the USB socket
Oval RF antenna
LED transparent window
Cup -shaped light parts
Two white glass fiber flame -retardant strips are fixed on the cavity

In order to make full use of the high direction of space to reduce the occupation of the battery thickness size, the sinking groove structure is designed in the inner side of the cavity to place flexible circuit boards and glue strips.

Due to the misleading appearance, it was thought that the internal structure should be more boring before disassembling. With the deepening of disassembly, the presence of various wonderful design is unexpected. The most frustrated part of the disassembly process is to remove the glass and last for about an hour. After removing the glass plate, the remaining gel back washed for half an hour. However, I will generally open a movie in this simple and boring link, so it is not a waste of time.
Under a simple appearance, Tea hides the exquisite hardware structure. In order to integrate the magnetic suction and battery into the thin body, the cavity and the cover plate have been carved and suppressed. The keys were originally insignificant, but there were still complex designs in Tea. Electrical parts, components are selected as superior, and welded welding.
TEA main circuit architecture: ES9281ac Pro/QCC5125/RT6863D.
TEA is made into a small fresh appearance for men and women, which is very different from Khadas’s consistent style. After removing the glass board, the geek wind was a bit back. In terms of personal taste, I think the naked magnetic structure is very mechanical, looks good, and even looks better.
Audiotop disassembling laboratory has previously analyzed more than ten portable decoding products. So far, Khadas TEA is the most special structure and the most detailed design. If you look at the complexity, it is one of the best levels of craftsmanship.
