Good products

For Arduino Compatible Nano Size Board

Shipping to United States took a little while but everything arrived in good shape so good experience and all. No communication was necessary and it seemed everything was shipped on time. I don't think the products necessarily need specific documentation since what I bought was some standard stuff, the 24mhz logic analyzer and two nano arduino boards. Thanks goes to the seller.

The best little digital oscilloscope available.

For Original JYE Tech DSO-SHELL DSO150 15001K DIY

This is my second JYE-DSO the first has been faultless for a couple of years now. I use them more often than my standard mains oscilloscopes because they are just easier to fire it up off a 9v battery and take up far less work space than my bench units. There are limits (200KHz, 5mV-20volts/div, 500Seconds-10uSecs timebase) but for maker projects they are well suited. A steady hand when putting the kit together and average+ soldering skills helps but no surface mount components in the 15001K kit.

The display of frequency, voltage (P-P and RMS) and duty cycle is great for Arduino or ESP8266 debugging (particularly PWM outputs) and the triggering is stable. A 10Xprobe extends them for mains-level or Vacuum tube applications, so get one of those to complete your kit.

This last unit arrived two weeks earlier than expected - a definite plus - I was keen to get it up and running.

Nice little board

For USB Development Board

This board has everything that a CY7C68013A developer board needs:
* A reset switch
* A jumper to disconnect the EEPROM, in case you screw up programming it
* Every single available pin except WAKEUP, not just GPIOs, is broken out to the headers, even SDA/SCL, making it trivial to e.g. add a larger EEPROM
* A power switch is a nice touch given the 3V3 power available on the headers
* Four mounting holes are nice too

Regarding the following:
> With the board firmware can be achieved through the core function of the logic analyzer.
This means that the board is programmed to appear as a device 0925:3881 Lakeview Research Saleae Logic using the on-board EEPROM. There is no actual firmware inside, it uses a "C0 load". It will work as a logic analyzer with any supporting software (e.g. PulseView), however it is not ethical to ship a device using Saleae USB VID/PID. Instead, Sigrok's USB VID/PID, 1D50:608D, should be used, which will also enable using all 16 possible channels in the logic analyzer, not just 8 with the default VID/PID pair. See https://www.sigrok.org/blog/sigrok-firmware-fx2lafw-013-released and https://sigrok.org/wiki/Fx2lafw for details.

The only other downside is the lack of schematic.

Very stable operation.

For DIY LED Music Spectrum Display Kit 16x32

Would be better if frequencies above 1Mhz where more fine tunable.Great kit , very stable output.I would buy it again.

Very noise free Voltage Regulator

For Original Hiland 0-30V 2mA - 3A Adjustable DC

I'm very impressed at just how noise free the output is.Yes I would buy this product again.It was easy to build and a great addition to any workshop.

Very nice programer.

For USB Universal Programmer

Received it today. Tested and works 100% with all my EEPROMS (27C512) which is my main usage. Little old software, but works well with Windows 10.

Great customer service

For 5Pc ATmega328P Microcontroller

My initial batch came a bit bent, but the seller quickly responded to my message regarding the condition of the package and shipped out replacement parts quickly. Great service!

A Decent Product

For TEA5767 FM Radio DIY Kit 87MHz-108MHz

The Keypad works as expected. However no documentation is provided to specify the Rows and Cols number of the circuitry so it took me a while to figure it out. The Rows and Cols numbers do not follow the Arduino Example out there and make sure you switch the Col0 with Col2 and switch characters '*' and '#' in your array to make the keypad work properly. The quality of the keypad is decent and even though some of the keys feel like they are already worn out, they still work. I may purchase this product again.
