4 digit display module is usually a 12 pin module. In this Grove module, we utilize a TM1637 to scale down the controlling pins into 2 Grove pins. It only takes 2 digital pins of Arduino or Seeeduino to control the content, even the luminance of this display. For projects that require of the alpha-numeric display, this can be a nice choice.

Grove - 4-Digit Display
Grove - 4-Digit Display module is a 12-pin module. In this module, we utilise a TM1637 to scale down the number of controlling pins to 2. That is to say, it controls both the content and the luminance via only 2 digital pins of Arduino or Seeeduino.
I have the 4 digit Grove display and 2 of the zip files on the Wiki page have the same error. "the compressed (zipped) folder is invalid or corrupt. The folders are Grove 4-Digit Display V1.0 eagle files.zipQuestion by: admin on 2018-12-18 02:35:15

Hi, i want to show an analogical value from analogical pin, for exemple 924 on the 4 digit display. How can i do this ? How may I separate the units, the tens and hundreds ?

if you want to connet it to micro directly without arduino,you will need a USB to serial line, and the protocol is 232.Answer by: admin on 2018-12-18 02:35:15
I am interested in using this on a plain old, non arduino, micro. Is the interface documented somewhere ?
AndrewQuestion by: admin on 2018-12-18 02:35:15
i'm sorry,we don't have interface document which connecting to micro,but our product can connect to micro without through arduino.you can connect it to micro directly by Serial communication.Answer by: admin on 2018-12-18 02:35:15
Hi, i'm using your arduino library from Github, is there a way to show characters other than the 0-9 and A-E, for example, the displays are perfectly capable of displaying characters such as 'H','g','y' etc...Altering the .cpp to pass in a different heQuestion by: admin on 2018-12-18 02:35:14
Of course you can. You may need to modify the example .cpp for your own purposes.

Hi I'd like to mount this through an opening in a PCB from the back. I need the dimensions of the 7 segment part of the unit so I can create a cutout. What are the exact dimensions of the 7 segment display? (or a link to datasheet). Thank you!Question by: admin on 2018-12-18 02:35:14
Exactly 30mm x 14mm for the quad 7-segmentAnswer by: admin on 2018-12-18 02:35:14
As I need to display times in seconds and milliseconds, I needs a variant with decimal points instead of the double-dot.Question by: admin on 2018-12-18 02:35:14
Such as this Adafruit one, which has four decimal places and a colon after the 2nd segment:

I am using base shield v1.3 and would like to use Groove 4 digit display. D2 and D3 ports are used for some other purpose and only free available ports on my base shield V1.3 are D7 and D8. I have some questions in this regard
1) Can I use D7 (clQuestion by: admin on 2018-12-18 02:35:14
Does not require PWM, so you can use any available digital socket on the base shield.
Most Grove sensors only use 3 wires of the 4 in the socket, so you can use the adjacent socket.
This sensor uses all 4 wires, so you must keep the next digitalAnswer by: admin on 2018-12-18 02:35:14
