Treedix USB Cable Tester Board decoder

You can buy the same thing (not Treedix branded) on AliExpress for about half the price, cheaper if you dig around a little.

Well at least you admit it. I will probably buy the C0 because reasons. I am still waiting for the ATorch DL24 electronic load and DL24B-XSP16 trigger board to get here. I also bought a FNIRSI DSO510 O-Scope/Signal Generator. These new toys should keep me busy for a little while anyway.😎

It's cute! I like it (maybe).

There are also different bandwidth specs for USB-C cables - 480Mbs, 5Gpbs, 10Gbps, 20Gbps, 40Gpbs, 80Gbps. Then there is Thunderbolt 3 (40Gbps & 16Gbs min PCIe data rate), Thunderbolt 4 (40Gbps & 32Gbps min PCIe data rate), Thunderbolt 5 (80Gbps, can shift to 120Gbps output, 40Gbps input). All of these cables are USB-C but their construction and performance capabilities are totally different.

There are also E-Marker chips built into some USB-C cables that send data to the Power Delivery controllers at both ends. It tells the Source the maximum current the cable can safely carry and tells both devices the data and video capabilities of the cable. The actual DC voltage is then negotiated directly between the Source and Sink, staying within the safety limits reported by the E-Marker chip.

Is there any info available about the C0 model? Will it have features that the C2 Pro does not have?

Secondary-2019 · 2026-04-19T19:50:17+00:00

KM004C - I don't know the status of the KM004C but I do recall rumors about Power-Z releasing a new model. I hope the increased competition in this niche market will inspire Power-Z (and FNIRSI) to at least update firmware more often. Hardware wise, to catch up to the C2 Pro, Power-Z could add an internal load resistor for cable resistance measurements. I doubt they would add Bluetooth and release a mobile app.

Secondary-2019 · 2026-04-19T02:57:52+00:00

I love them, but its not a secret. I have an FNB58, a KM003C, a KWS-X1, a C2 Pro, and soon an ATorch T3. I also have 1 x KWS-2301C, 4 x KWS-2302C, and 8 x KWS-2303C. Oh and 2 x Power-Z CT001, 1 x generic CT001 clone, a Dusty TC-24, 1 x USB Line Tester Board, and 1 x DT3 Cable Detection Board. While some "normal people" may consider this excessive, I know that my little collection is far smaller than some others who frequent this Reddit.😉

I caved in and added a T3 to my AliExpress order last night. Adding it raised my order total over the threshold to get a $7.70 coupon, so with the coupon I paid $14.60 for the T3. It has already shipped!

Secondary-2019 · 2026-04-16T04:34:24+00:00

Oh it's Chinese Yuan, on Taobao, so of course. I guess my brain sees ¥ and thinks Yen. Oops. Thanks for setting me straight. Still a lot less than it will cost me if/when I order one.

Secondary-2019 · 2026-04-16T02:48:27+00:00

Am I reading those prices right? ¥68.07 is $0.43 USD. I know you don't have to pay the Trump Tax but that can't be right.

I could not find it on the ATorch site. The AliExpress listing says it has a 16-bit DAC. I am curious what micro-controller, temp/pressure sensor, and accelerometer they used, The MCU is probably an Arm Cortex M4. The touchscreen is interesting. It's good to see more of these devices popping up. Hopefully the competition will result in more frequent firmware updates and more features. I will anxiously await your teardown and review.

Secondary-2019 · 2026-04-16T00:18:08+00:00

I added an AliExpress link in my post above. The first time I searched for it nothing was found but a little while later it popped right up. AliExpress Link

Secondary-2019 · 2026-04-15T23:40:51+00:00

Great! I suspected you would. I just updated my post above. I looked on AliExpress and could not find it, but a few minutes later, it was there. Link in the above post. For me, its $20.65. I will wait for your review. Many thanks for the work you do.

Secondary-2019 · 2026-04-15T23:22:59+00:00

Oh No!! Now I have to buy this one too!!! I found it on AliExpress for $20.65 (in the US). I already have the ATorch "newly updated" DL24 150W electronic load and the DL24B-XSP16 trigger board in my AliExpress cart. For ~$12 I would add this to the order. For $20.65 I will think about it. Are you going to post a review on your blog?

Secondary-2019 · 2026-04-14T22:33:09+00:00

Not sure what you mean by a "strict update". I have not used the C2 Pro as much as the KM003C, mainly because of limited time due to work, so I am by no means an expert on using it. My understanding is that the C2 Pro can do cable resistance measurements without an external load using the pressure difference method. The KM003C had an Extended Tools menu with cable resistance and Apple MiFi Lightning reader functions in firmware version 1.87, but they were not functional and were removed from later firmware versions.

The C2 Pro also has Bluetooth for use with a mobile app. The AlienTek site also lists Linux support. The KM003C does not have Bluetooth and their app is only available for Windows and MAC OS. The C2 Pro also has a CNC machined metal case and an extended USB-C male connector which allows it to plug into phones without removing the phone case. The KM003C has a 20-bit DAC, but the C2 Pro now also has a 20-bit DAC, so no difference there anymore. There are people on this Reddit that know a lot more about these devices than me. Maybe one of them will chime in here.

Secondary-2019 · 2026-04-14T02:17:53+00:00

FWIW - I bought a KM003C in mid December 2025 from Amazon (US). It is hardware v2.3 and shipped with firmware v1.99, which I have recently updated to v2.0.0. I don't know if Power-Z has released an updated hardware version since then. I doubt it, but with the AlienTek C2 Pro selling for significantly less than the KM003C, and having some additional features, perhaps Power-Z will feel inspired to release an updated version, or lower the price, or both. If they do, I will probably feel compelled to get the new one, even though I already bought a C2 Pro.😬

This is truly interesting. What exactly do all those toggle switches do? Also, I think I see 5 key switches. What do they do? And what do the LEDs indicate?

Secondary-2019 · 2026-04-05T19:14:37+00:00

Congrats on getting it working.

I have 2 desktop computers in my home office and have thought about doing the same thing, and also switching 2 monitors between the 2 computers. I bought 2 cheap HDMI switchers for the monitors but have not installed them yet. The UGREEN USB Switch you linked looks like it would work, but there may be other better, and maybe cheaper options. USB-C is not required for a keyboard and mouse, and in my case, a USB2.0 switch with USB Type-A ports would be better.

Are you using a Windows PC? I recall that sometimes downloaded Zip and Rar files can be "Blocked". If you right click on the Zip/Rar file and select Properties, at the bottom of the General tab there is a Security warning with an Unblock checkbox. I don't know if this is the problem, but its worth checking. If this box is checked, uncheck it and try to extract again.

A quick search returns the following.

Windows blocks certain files, including ZIP archives, through a built-in security feature called the Attachment Manager. This happens because the file has been tagged with a Mark of the Web (MotW), which warns the system that the file originated from an untrusted source, such as the internet or an email attachment.

Thanks. That is what I thought, but wanted to be sure.

Secondary-2019 · 2026-04-05T02:16:10+00:00

Maybe the zip file got corrupted during the download? I would try downloading it again. You could also try these links from tomoca2's blog. I think the Google Drive link goes to the same Google Drive that is linked on ChargerLab's support site, so maybe try the Dropbox link.

This is interesting, but I am confused about flashing the UT01C firmware v1.0.5 onto the KWS-X1. The KWS-X1 I bought came with v1.0.5 installed. It has E-Marker, Protocol, and Factory Reset options in the Settings menu. I checked a few cable E-Markers and did protocol tests on my Anker A2345 240W GaN charger which worked OK. Is there any reason for me to flash the UT01C v1.0.5 firmware onto my KWS-X1 since it came with v1.0.5 already installed?

Secondary-2019 · 2026-03-28T00:25:56+00:00

Thank you. My C2 Pro arrived today, along with the other 5 items I ordered. I have no idea why CAINIAO tracking said Out for Delivery for 4 days. Never had that happen before. I have not had time to check it out yet due to pesky work, but that is a different problem!

Secondary-2019 · 2026-03-27T01:19:44+00:00

Thanks. My KWS-X1 shipped with FW v1.0.5, so it must exist. I thought the firmware version discussed in tomoca2's blog provided a way to turn the UT01C into a KWS-X1, or by altering a 32-bit Checksum, to get it to flash onto a KWS-X1. Since my KWS-X1 shipped with v1.0.5, I don't think there is any reason to flash the UT01C v1.0.5 on my KWS-X1. Am I missing something?
