Customers' Reviews

I got the board. The quality of PCB surprised me. Everything works well for these production boards.

The quality is excellent and the price is affordable. Even if you don't make prototypes yourself, everything is fine with these production versions.

This is a test project broadcasting different frequencies. The quality is excellent, the price is affordable, and the finished product works well. PCB is worth recommending. I'm very satisfied.

Fast and quality PCB fabrication, delivery on time.

Very good service from cnsmt!. The order process went very smooth, clear communication about the status of the manufacturing process and on-time delivery! The PCB's are of an excellent quality and many satisfied customers of this product. I am ready now to order a second batch and to order PCB's for new projects!

Prototype boards were made with great quality! Extremely fast shipping! Even very helpful when I forgot to include a layer in the files!

PCBs were received less than a week after orderng. I am extremely satisfied with the quality of the boards, the processing time and the service.I already populated the boards and i am impressed by the quality.I will definitely order again. Thank you.

Hardware-On-Top addon for Raspberry Pi / ASUS ThinkerBoard with TAS5825M stereo amplifier, 30W RMS per channel.BassOwl-HAT is an expansion board for Raspberry Pi and ASUS ThinkerBoard, designed for Hi-Fi music playback.It is powered by the TAS5825M from Texas Instruments, a stereo Class-D Smart Audio amplifier able to deliver up to 30W RMS per channel. BassOwl-HAT does not require any external device or amplifier to play music, two loudspeakers can be connected directly to the screw-terminal connectors.BassOwl-HAT requires an external power supply with volgage between 12V and 24V to function properly. It is not necessary to connect additional power sources, because a dedicated 5V/3A DCDC converter will back-power the Raspberry Pi.Two optional MEMS Microphone modules can be connected to the BassOwl-HAT, for adding voice-control capabilities to the system.

The printed circuit board itself is absolutely wonderful and affordable. It is made to the highest quality standard I can expect!

Automatic Hand Washing board incorporates Atmega328PU and few external components. I received the boards (10 pieces) on 17th October 2020. I must confess that cnsmt has exhibited a high level of professionalism. In fact, the packaging was superb. I assembled one and it worked to perfection. I will surely work with them all the time.

Excellent PCB, works very good, very professional finish, looks pretty nice, I'm very satisfied with this PCB. Thank you !!

Professional PCB, price concessions, professional finished product work results are fast. So far, it's been pretty good.

Very satisfied with my fourth batch of PCBs; fast service, good price and excellent quality!

Arduino based telephone to radio system autopatch prototype to absorb the calling party's touchtones and re-generate at the right level for radio systems. This board is a great quality for prototyping and solder rework (pads don't lift). Since it is within the 100mm x 100mm square in the $5 promotion, you cannot beat the price including the fast shipping. Now that this part is complete, I just ordered another batch of boards with all the tweaks and changes for the production boards.

I designed this PCB for one of my products, it consists of a MIDI controller for pedals like the Digitech Whammy.As always happy with these products, continue to make my prototypes and final series. Thank you very much.
