Guide: With the popularity of smartphones, the previous function machine basically does not see the trace, even if the business hall "charge the phone" is sent to the intelligent machine. Many years ago, the home installed telecom broadband sent a Huawei C2601 function machine, supporting Telecom's CDMA format, free, dismantling the dying design.
The outer casing is more old, see the following picture, but as a call is really good, the gray often recalls the long standby of the function machine era, I used to use the 30-day lattice cottage, and now I don't see the trace. The topic is far away.
The quality of this mobile phone is a lever, and there is a fight with Nokia's bricks. It is not going to talk. The screw on the phone is still a high-end 6-angle screw, and the careful friends may find that this mobile phone has not been removed before, and the fragmented post will remain, this is the first dismantling.
The 4 screws that are unscrew the back can be very convenient to open the C2601, you can see the head in front of the front panel, the back cover motherboard is a liquid crystal display screen and the film button, now in some miss the button, complete Can send text messages blind.
Removing the motherboard can find the fixed CMDA antenna on the back cover and the vibration motor, the motherboard is also very simple, and a large shield is completely covered with the main chip of the phone. Like this simple function machine, digital signal integrity can handle very well, the trace is really not a problem.
Looking down the shield surprised to find a high-pass program, Oh mygod, Huawei's high-pass program will now make a concept, and it is conceivable that this mobile phone has been so early, and the Huayi, who has already begun, has not begun.
Quite streamlined programs, high-pass QSC6010 + Intel 38F1030W0ZTQ0 memory, QSC6010 chip is a low-cost scheme chip for CDMA2000 mobile phones, based on ARM9 embedded micro-processing system, including: channel codon system based on ARM9 embedded microprocessing system , Control processor subsystem, DSP subsystem, RF subsystem, and power supply. Look at the board layout can also instance of high integration of QSC6010 chips.
The dismantling of C2601 is pure interested. It is not broken by the comrades of the belly black. See the picture below, there is a truth
Because there is no card, it is displayed, but can call 112. When you look at the current displayed on the digital power supply, the power consumption called the phone is very low, this is the mobile phone of the CDMA system, it is not a GSM mobile phone, so In the past, many pregnant mothers were exchanged from the GSM mobile phone to the CDMA mobile phone, why no it, low radiation.
The advantages of the CDMA mobile phone are still very much, such as the maximum transmit power is only 0.2W, and the maximum transmit power of the GSM mobile phone reaches 2W, which is 10 times that of the CDMA system, the radiation is natural, the CDMA mobile phone will automatically calibrate time, no need Manual setting, high confidentiality.
Simple disassembly is here, I hope everyone likes it. There is new gadget in the future, you don't want to store, the bad thing will come over to share it, please remember the ID, learn Lei Feng, thank you.
