Highly recommended – JY-MCU 16X Digital Tube Red LED Module Reviews

posted by buskas on 08/28/2012 Certified Owner

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
- Cheap - Comes fully assembled - Cables included - Adjustable brightness via library - Good quality
Cons:
- Only 7 segments, suitable for numbers only - No documentation - No spacers/screws included for mounting (but suitable holes in the PCB are provided)
Other:
To use this with an Arduino, you just need to get the TM1640.h library here: http://code.google.com/p/tm1638-library/ I have provided an example sketch here: http://pastebin.ca/2198761
Bottomline:
Highly recommended! Everything about this display seems to be as it should. I got two, and after getting them to work immediately ordered two more, and some 1638s as well.
