4 digit display module is usually a 12 pin module. In this Grove gadget, 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 alpha-numeric display, this can be a nice choice.

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 he
Of course you can. You may need to modify the example .cpp for your own purposes.
Here's one I was working on for the GrovePi: https://github.c
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!
Exactly 30mm x 14mm for the quad 7-segment
As I need to display times in seconds and milliseconds, I needs a variant with decimal points instead of the double-dot.
Such as this Adafruit one, which has four decimal places and a colon after the 2nd segment:
someone could make it work with a beaglebone black?
How do I order a stencil with my order for a two layer pcb?, the web site does not seem to have an option for this request?, also do you have a price calculator or is the stencil included in the price of the PCB?
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 (cl
Digital port 2 on Base shield means digital 2 and digital 3 on Arduino board. You can use digital 7 and digital 8 for this device, just modify the code:"#define CLK 7""#define DIO 8". And plug it onto the D7 port of Base shield(digital 7 and digital 8
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 digital
different colour options please [blue, yellow, white and green]
What is the protocol for the serial comms ?
if you want to connet it to micro directly without arduino,you will need a USB to serial line, and the protocol is 232.
I am interested in using this on a plain old, non arduino, micro. Is the interface documented somewhere ?
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.
