Right, but what about CC drop-down in this case? Should it be enabled or disabled?
Youngcrazy: Pete7874:Sounds very confusing. So what if you want to trigger a specific protocol and apply load using that specific protocol, for example PD 20 volt?
at first,we should make sure that charger support that protocol, then you set the protocol you need,when finished setting,connect it to your load

Function01: independently charged
“we can see there is a Micro-USB port on TC66©, it is used for independently charged so that TC66© will not consume system power,and we can have more accurate measurement calue. On the other side, when TC66© is independently charged,we can measure voltage from 0.005V.”

they update everyday,and you guys can click “follow” at eshop of RD to get coupons(this is an advertisement )

When are they going to start shipping these devices?
For now, they still seem to be testing them. Aliexpress will cancel the order if it’s not shipped out within X number of days.
The TC66C i ordered a few days ago says still processing (processing time 13days). I hope they will shipp it until then. The option to use it bidirectional is really helpfull. It makes checking the charge current (position of the device on the charger ) of my wireless charger much more easy.

I asked them and they told me that thay started shipping but they need time to Pack so many orders :cry:

we can only wait, and they won’t like disputes so they will send your package in time, :face_with_monocle:
"-6digit voltage and current, resolution is 0.0001V(0.1mV)/ 0.00001A(0.01mA)"
What is the accuracy in % for voltage and current readings?
“–6digit voltage and current, resolution is 0.0001V(0.1mV)/ 0.00001A(0.01mA)”
What is the accuracy in % for voltage and current readings?
Voltage measurement accuracy:±(0.05%+10digits at 23℃)
Current measurement accuracy: ±(0.1%+20 digits, at 23℃)

My order is shipped. No the long wait beginns.

That means for example, that for 1.000A current your meter has accuracy of 1.000A+-1mA, so what the point of displaying 6-digit value, if you don't actually know last two digits at all?

Pete7874:Where is the PC software?
The instructions refer you to this location:
My FilesBut when you go to this location, there is only an .apk file there which is not a Windows executable.
they said they will upload PC software in two days,
Sounds like they are still writing the software, while the devices are on their way to the customers.
Lucky for them, they still have about a month or so to finish coding it.
so what the point of displaying 6-digit value, if you don’t actually know last two digits at all?
Thats a very good point! Why adding digits if the accuracy is not there?
I still ordered one because of the bidirectional USB C connectivity.
And the accuracy is good enough for me (for the things i plan to use it for).

It looks like a nice device, but this 6-digit "feature" is nothing but marketing BS with goal to increase sale, because, you know, other similar devices have only 4-digit "accuracy".

It depends on users. Usually 4-digit “accuracy” is enough, but it can not meet everyone’s needs, so we just choose the device what we need
The point is your TC66(C) device has useless extra two digits for voltage, current, and power, so why display it if those last two digits are basically noise and contain absolutely no useful information?

you can read their introduction or watch vedio, when you want to use 6-digit accuracy, it is charged by independent power supply and you can see they are not useless, 6-digit accuracy
means the fifth digit is credible,4-digit accuracy means the third digit is credible, that makes the difference.
if you want to know more,please contact RD offcial ,I’m not the designer :nerd_face:
Thank you for your article, it helps a lot. If other friends have interest in TC66C, you can contact me and I am willing to communicate with you
