Receive quickly and in good condition, packaging OK. For assembly, you must also provide a multimeter for the resistors. Indeed, the marking (4 bands of color +1 for tol) is not always clearly visible. For the pitches, the marking on the board is sometimes not very clear. Refer to the photos on the site (ok I re-wrote on see image 2). The resistors are in the tolerance range of 5% error (while the brown band = 1%). The measurement of a 1000 ohm can be 970 ohms or 1001 ohms. A measurement repeating with a precision multimeter should confirm. All electrolytic capacitors are 100uF by 16Vdc, so no need to sort them. The pads for the connection of the elements are not simple to handel for soldering. Care must be taken that the pad does not "go" to the other side while soldering. It's quite a hassle to solder. Be careful not to overheat though. NOTE: JP1 bridge must be closed (open only if there is the option for the charger)! R29 is not installed, it is normal, at least for this version. Ok, the module is working correctly: Note: point V4 is at 5V and not at 1.5V ! Warning: if a key is stuck at startup (boot), the screen remains frozen when the version is displayed. Same with COM. If the COM port is open, this blocks the start of the unit. Otherwise, the COM works fine. Note that for the coils, the value of Z is at x.xx while it is displayed at x.xxxx. Further tests need to be done. For the case: It's really tricky to install. Be careful not to over-tighten the screws or risk cracking - breaking the case (upper or/and lower plate). Be careful not to jam a key. In overall, the product is fine and good. I think the battery connector has to use (take it in account with the to case) this will make the unit autonomous.

Q: Will the display work with Ubuntu Linux?

Bricola Hello, I've put some info on the question : Is there a place to find more themes than the already installed? By the way, there is a possibility to use (run) the software on other OS, like Linux, MAcOS or other operating systems that support Python 3.x . It existing a "Turing Smart Screen Python” project hosted on Github. Take a look at cnx-software com

Bricola Shell only (without LCR module) is about 10$US, the LCR module itself (without the shell) is about 56$US. You can clearly see the difference while select.

Q: what is the current output of this device? thank you.

尋ねた BG514437481 に 2022-08-09 04:21:39

Bricola Hello, I've just ordering one of this and waiting for it to arrive. Anyways, if you want to know the max current the output relay can support , regarding the specifications given : 20A by 12Vdc or 10A by 220VAC. No other output, no active output. Only a relay. It's a simple thermostat device.

Q: Is this a regulated output since there is a potentiometer

尋ねた BG401755184 に 2021-12-07 02:26:00

Bricola AS jltt19 wrote on the 16.07.2020 , the output voltage is not fixed to 5V but can be between 2,7V to 10V depending of the pot setting from the factory. It is necessary to check and make the adjustment with the potentiometer for 5V. So, prior to supply the device that need the 5V, check the output of this module with a multimeter (voltage selected of course) and adjust the potentiometer. Then connect your device and check the 5V again, that might have drop a bit regarding the load, and if needed adjust carefully to 5V.

Q: There are 2 usb-c port in the back.. where to connect?

尋ねた jvp4ant に 2022-05-26 03:17:33

Bricola Hello, I know, I've got the same question for myself, the installation paper was only half and cut ... After looking on the Internet, I found a video and some other infos. In fact, you have to connect the USB-C cable to the USB-C socket on the edge of the board, not the one in the middle (even thought there is not enough place for the connector). Install the software, connect the unit, install the driver (if needed), select a Theme and RUN. That's it.

Q: Is there a place to find more themes than the already installed?

尋ねた Skaravaios に 2022-04-27 05:26:44

Bricola I do not know, but you can create your own theme. There is a video you can watch on YTB : "_kRdJ65wO0o" that have a part which gives you tips how to do your own theme. Note that the size of images has to be 320x480 for portrait and 480x320 for landscape, has to be png. With the Theme Editor, you can load an existing theme (config directory) and change how you like. UI-Image is the back. By the way, there is a possibility to use (run) the software on other OS, like Linux, MAcOS or other operating systems that support Python 3.x .

Bricola wujiahui : No, this LED module does have polarity ! You may look for datasheets like, for exemple RWL-R1025BB or YSLB-10251B5-10. The positive is on the side where the type is written on.

Q: what are the values of SMD resistors

Bricola The little SMD resistor is 3Kohms. You will get 2 of them, so one to solder and one as a spare part if you lost or damage it.

Bricola Hello,this module is equal to the W3230. I found a Chineese - English manual : that tells P6 = Hight-temperature Alarm (-55°C to 120°C Factory is 120°C) , P7= Data Lock (On-Off Factory is OFF) , P8 = Factory Reset (On-Off Factory is OFF). Hope this help.
