And of course the main ports: two USB-C (father and mother). Packaging and appearance
There are six virtual desktops available for the end user: The presence of a fully functioning automatic trigger (scanner) of charging protocols expands the available options. It is made both to save energy consumption and for quiet operation (for example, so that it does not distract with light at night).
Well, in the end, let’s take a closer look at the capabilities of the tester itself. It has all the https://tonaton.ng/s_254-makeup-trolley features of the more expensive RD TC66 counterpart.

Fifth table with tester settings. Interface: USB-C in, USB-C out, MicroUSB HID < br />Trigger: Yes, Qualcomm QC2.0/QC3.0/Huawei FCP/SCP/Samsung AFC/PD3.0/2.0 Auto-trigger charging protocols, color screen, memory of the last selected screen, the ability to update software – all these are undoubtedly the advantages of this model. — Looks visually the same as many modern testers, ie. in the usual way.
RD TC66 vs FNC88 – external batteries With all this, of course, there are disadvantages: first of all, this is very raw software for updates, as well as the increased dimensions of the tester itself relative to its competitors. It automatically recognizes that the FNC88 tester is connected with the current firmware (in my case it is V1.00). Built-in thermal sensor. There is no case as such, everything is assembled like a sandwich.
There are only four of them: three are the main navigation and one for switching the PD mode (on / off).

USB-C PD tester Fnirsi FNC88: full protocol trigger and software upgrade

Model: FNC88 Set forcibly any supported (for example, 9V or 12V).
The last, sixth table — tester operation mode with screen backlight turned off. Capacity: up to 99999.9 mAh or 9999.99 Wh, 5 cell memory You can select the screen brightness mode, language, rotate 180 degrees, change Celsius to Fahrenheit, perform a master reset, etc. – mains chargers etc. And for testing devices with USB-C ports, the thing will be indispensable. The process takes less than one minute.
The main part is the central one, it is a board with
screen, all ports and microcontrollers. Measured voltage: 0-> 24V
Conclusion
Internal structure Select the desired firmware file (V1.02) and press START. I hope this bug will be fixed soon. The tester arrived in an https://jiji.ng/12-engines/lexus-ls-460 antistatic bag, inside a plastic box.

Through the USB HID (microUSB) port, we connect the tester to our computer. – car chargers Based on (STM32) F150GB controller, 0.010 Ohm shunt, 32Kb non-volatile EEPROM P24C256, in addition there are two voltage stabilizers 6203A< /b> and a dedicated ADC for precise measurements – INA226. The scope of the USB-C tester is primarily a field test of various mobile gadgets with the appropriate port:
The second table is very similar to the first, but some non-basic items are replaced here by showing the voltages of the data lines and the current protocol (pictured below is Apple2.4A). Unfortunately, it was not possible to recognize the marking of the PD chip. After this time, we have an updated version of the software in our tester. Software update To find the necessary programs and firmware, go to the product page and find a direct link to the file storage there.

The product was provided for writing a review by the store. The first table displays the time (it can be left or forced to start), current direction, temperature, voltage, current, power, resistance, memory cell (there are 5 in total), mAh and Wh counter .
Fourth table – manual check of the charging protocol.
Specifications: It has the same features, including auto-trigger charging protocols and the ability to update software. At the same time, the cost is noticeably lower.
