First thank you for the explosion
30 pieces or SF ship, although it is a special, but the experience is not bad.
Nothing to pack
Production is 2012, it seems to be stored in the clear.
The function seems to be based on mobile portable, but 1700mA battery is a bit. . . . .
The packaging is quite full.
Mainly the host, battery, network cable 1M, and miniusb2usb.
The battery is so big, but both sides are empty, the main unit is 104 × 81 × 23mm (long and thick). It is more difficult to stuff 10ah, but a 7000mAh polymer battery should be placed.
I watched the online disassembly before I bought it, but the price of 299 that year is really a hurry. Only one disassemble map online is also quite simple. Some chips are not very clear, but the chip is RT5350F. Single chip microcomputer, I saw DDR memory and a SOP8 package chip, I would buy it back to try it. Can you play.
This is the opposite side, the space is quite rich. Looking at the TTL port and a COM port on the PCB board, this COM port looks a bit like JTAG definition standard, I don’t know if it is. The above picture is flipped as shown below:
The front is the main control and memory chip, and the picture of the PCB is 2011. I miss the high school time at that time. . . .
The main control is RT5350F, data sheet
The main frequency can reach 360MHz, MIPS core. Although this kernel is not arm, it is authorized to freely modify the kernel and the same frequency power consumption is still better than ARM.
The film has a 2.4G RF antenna and supports most of the protocols, up to 150Mbps rate, a USB2.0, a 10 / 100M adaptive network port, also with SPI, I2C, I2S, PCM, UART, JTAG (see the previous COM port should be JTAG) these communication interfaces.
EM63A165TS-6G, not DDR memory is the memory of SD-DDR, guessing. . . . This memory is 32MB
The SOP8 packaged chip found on the online picture, guess it is the 8M Flash, 25 Series flash memory, Q64-104 Hip Cfeon
(The power part of the power is forgotten)
There are many developing boards and materials on the main control of RT5350F, and many portable routes have also been used in 2012.
The configuration is also the standard 32M RAM + 8M ROM of the development board, which has increased its firmware to the official website or to modify firmware.
The system requirements of OpenWRT to RT5350F are 32M RAM + 8M ROM, just reach standard. It seems that it is not bored during the Spring Festival.
This battery is a bit too much, just put a packing battery into a plastic box. You then wrap it with a rubber.
These two buttons look like a recovery initialization, one is WPS function. But, why is it a button on the housing.
Finally, the picture will look at the antenna (upper right corner), there is obvious welding trace, and the previous picture has nothing to say that there is a significant trace of the PCB board to wash the scrubbing water, but this welding trace instructions this board After washing, it was repaired. Welding should be the above R1 resistance. Is there any amplifier on my antenna behind the R1 resistance? ? ? ? I don’t know if it is originally not yet. . . . . .
After reading the picture of Section 2, you also saw a lot of components without welding. I think it is basically a filter capacitor, a voltage regulator diode, and some of the 12 Euro resistors (these things are used according to packaging, logo, The surrounding chip and the connection of the wire effect speculated) These can have no components. But this cost is costly. . . . . . Sorry at the price of 299.
30 dollars bought something, and I’m going to be basically the same. From the cost, it is also very good to use the circuit board to remove the component in the future. The PCB plate version is in 2011, the starting time is 2012, and there is a trace of re-welding, it may be a return letter or official turning. Even so, but for me, it is worth it.
6, thank you
Thank you for reading, my own level is limited, and the spit is also said to say, welcome friends from all netizens to correct light.
