 VolcanoBox...Ahead of All

While everyone else was busy trying to keep up with FuriousGold, a new product is created to make FuriousGold more powerful, easier to use and more indispensable than ever, which is Volcano Box.
Digital resistanceIt achieves to pull up/down any resistor, this performs important role when detecting USB definition. It can analyze the accurate resistance value of USB D+pinout this to define USB definition precisely. At the same time, the functions of connector GND and VCC are accurate too. The box can detect phone connector GND and VCC accurately even without power supply from clippers, which means to realize detection and phone read/write possible when phone connector has VCC and GND definition at the same time without clippers. This is exclusively on Volcano. It's impossible to collect and analyze analog data when there is no digital resistance.
Completely GND and VCC control functionsAfter years of practice, we found out that box would have problems of no GND and VCC hardware design. Because many phones can't work normally without GND and VCC, especially for MStar CPU phones. If you cannot find phone's charger-pin accurately and set VCC definition to it, phone will not respond to read/write operation at all. When setting higher level to general SCM can only provide the current of 20mA. Firstly, there is no way to find out phone charger-pin; Secondly even when you know charger-pin and set it to higher level, phone will directly reduce it because of heavy current, as a result, it fails to play the role of higher level as well as abnormal of phone detection/read/write operaitons. ALl these experience has been proved and tested over years. Volcano's upper panel controls phone connector GND and VCC, which ensures phone to work normally and coordinate with box software analysis to detect charger-pin accuately. This function can be used to produce phone charger cable too. Other box can't provide standing current over 30mA for they only have one PCB panel. MStar CPU phones are difficult to achieve read and write on other boxes.
Set pull up/down to any pinoutYou can set any pinout up/down with a variable resistance value. Lots of dead phones TX connector is OC portal, which means higher level is open-collector, it will output lower level if you don't set pull-up resistor to TX. Volcano Boxcontrols flexible pull-up resistor value by changing the resistance. For example, some OM CPU phones can't read/write normally if you do not set 5-10K pull-up resistor. Many other phones can't detect or read/write without this functions. This is exclusively on Volcano and no other box has this function.
Selects resistor value from 390 ohm -800KShort two pins with resistor function can realize phone enter downloading mode, or other special purposes. This is exclusively on Volcano and no other box has this function.
Eagle EyeEagleeye is used for measurements of current. Its built-in analog metter and digital. It can show you how much milliampere mobile using. This is exclusively on Volcano and no other box has this function.
Internal powerful CPLDIts internal powerful CPLD provides filtered signal output. All the high frequency interference pulse has no access to phone nor to computer, thus it ensures no wrong interference between phone and computer, to make it work more stable. Meanwhile, CPLD also offers more powerful driving abiliry as well as a wider tange of voltage, making read/write to a higher rate of success. It will e very worse if box has no CPLD like read/write stability, immunity and driving ability etc.
Better software and hardware protected designThis ensures heavy output current from hardware design, but also guarantees it will not burn-out box or phone. That is because instant software current real-time monitoring as a watchdog protection, long time protection of thermal relay and over current resistance protection ensure the output current can be staibilzed 500mA but never over 700mA. Each pin has been designed for overvoltage protection and negative pressure protection. This is exclusively on Volcano and no other box has this function.
With a more reasonable USB pathway designVolcano core IC on-resistance value is only 3 ohm while other box uses more than dozens of ohm. Excessive access of resistance will inevitable cause phone USB work unstably or even not work completely. Other box uses excessive resistance will not support some phones read/write and this is confirmed by the practice already.
Test batteryThis function is used to have schematics for making your own cables for customers. For exmaple, make chargers, earphone cables etc. THis is exclusively on Volcano and no other box has this function
