This keypad has 12 buttons arranged in a telephone-line 3×4 grid. It’s made of plastic with sturdy buttons. The keys are connected to a matrix, so you only need 7 microcontroller pins (3 columns and 4 rows) to scan through the pad. It’s basically a sturdier version of our Membrane 3×4 Matrix Keypad and comes with 7 or 8 header pins pre-soldered on for easy plugging. Starting from the left, there are three column pins, and to the right are the four row pins. If yours has an 8th pin, it’s not used, and you can just leave it disconnected.
Features
- Standard Header Pin Connector
- Tactile type switches
- Over 1,000,000 operations per key
- Dimensions: 56mm Wide, 80mm High, 17mm Thickness

MT3608 DC-DC Step Up Power Booster Module
This MT3608 DC-DC Step Up Power Booster Module is a low-cost module that can step-up a 2 to 24V input voltage up to a 5 to 28V output at up to 2A. The MT3608 converter IC has over-current and thermal limiting features built-in to safely shut the device down if driven too hard. DC-DC boost converters step up the input voltage to a higher voltage while also stepping down the available current since the module can’t output more power than its inputs. This boost converter is adjustable and capable of outputting a voltage in the range of 5.0 to 28V at a continuous current of up to 1.5A depending on input/output voltage settings with 1A available with most settings.

1-Channel 5V Relay Module
1-Channel 5V Relay Module is a 5V 1-channel relay interface board with screw terminal, it can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on. The board has a high-quality relay, which can handle a maximum of 15A at 125V or 10AA at 250V AC. Relay has three connections – Common – C, Normally Open-NO, Normally Closed-NC brought out to 3 pin screw terminals which makes it easy to make and remove connections. The board has a power indication and a relay status LED to ease debugging. Power input and relay control signals are brought to header pins on the board. Hence, the board can be easily interfaced with our development boards using our jumper wires.
