This Matrix Keypad 4 X 4 has 16 buttons, arranged in a telephone-line 3x4 grid with a column of 4 characters (A, B, C, and D). The keys are connected into a matrix, hence only 8 microcontroller pins (4-columns and 4-rows) are required to scan the pad.

It's made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are connected into a matrix, so you only need 8 microcontroller pins (4-columns and 4-rows) to scan through the pad.

Details:

  • Pad Size: 76 x 76 x 0.8mm
  • Cable length: 85mm (include connector)
  • Connector: dupont 7 pins, 0.1 inch (2.54mm) Pitch
  • Mount style: Self-Adherence
  • Max. circuit rating: 35VDC, 100mA
  • Insulation spec.: 100M Ohm, 100V
  • Dielectric withstand: 250Vrms (60Hz, 1min)
  • Contact bounce: ≤5ms
  • Life expectancy: 1 million closures
  • Weight: 7.5g

How many pins are required to scan the 4 by 4 matrix keypad and how is it wired?
The keypad uses a 4 by 4 matrix and requires 8 microcontroller pins (4 rows and 4 columns) to scan it.
Can the keypad be mounted on different surfaces and how is it attached?
It has an adhesive backing and can be attached to nearly any surface by removing the paper backing.
What are the electrical limits and durability characteristics of the keypad?
Maximum circuit rating is 35VDC and 100 mA. Insulation is 100 MOhm at 100V with a dielectric withstand of 250 Vrms at 60 Hz for 1 minute. Contact bounce is less than or equal to 5 ms and life expectancy is 1 million closures.
What are the physical dimensions and cable details of the keypad?
Pad size is 76 x 76 x 0.8 mm. Cable length is 85 mm including the connector.
What resources are available to help with integration and usage?
Documentation and samples are provided including a datasheet, library, and tutorial.
