    Description

    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.

    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:

    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

    if you want to connet it to micro directly without arduino,you will need a USB to serial line, and the protocol is 232.
