4 Channel Relay Module (5v)
NPR 500.00This is a 5V 4-channel relay or four channel relay module interface board, and each channel needs a 15-20mA driver current. It can be used to control various appliances and equipment with large current. It is equiped with high-current relays that work under AC250V 10A or DC30V 10A. It has a standard interface that can be controlled directly by microcontroller.
- Size: 75mm (Length) * 55mm (Width) * 19.3mm (Height)
- Weight: 61g
- PCB Color: Blue
- There are four fixed screw holes at each corner of the board, easy for install and fix. The diameter of the hole is 3.1mm
- High quality Songle relay is used with single pole double throw, a common terminal, a normally open terminal, and a normally closed terminal
- Optical coupling isolation, good anti-interference.
- Closed at low level with indicator on, released at high level with indicator off
- VCC is system power source, and JD_VCC is relay power source. Ship 5V relay by default. Plug jumper cap to use
- The maximum output of the relay: DC 30V/10A, AC 250V/10A

4- Channel Arduino Relay Shield
NPR 650.00This relay module allows you to combine the processing power of the Arduino to devices that use higher current and voltage. It does so by providing four relays that are rated for 10A at 125VAC.
There are four relays that each provide dry contact outputs. That is to say that each relay provides a common (COM) , normally open (NO) and a normally closed (NC) terminal.

40-Pin IC base
NPR 45.00This ia a 40-pin IC base with pins spaced at 0.1(2.54mm) . It is usable for plugging in and out the IC during prototyping and to protect the IC from damage due to heat while soldering by first soldering the base to the board and plugging the IC later.

4017 decade counter
NPR 50.00The CD4017 is a CMOS Decade counter IC. CD4017 is used for low range counting applications. It can count from 0 to 10 (the decade count). The circuit designed by using this ic will save board space and also time required to design the circuit. CD4017 is as ‘Johnson 10 stage decade counter’.

5V Relay
NPR 100.00One of the most useful things you can do with an Arduino is control higher voltage (120-240V) devices like fans, lights, heaters, and other household appliances. Since the Arduino operates at 5V it can’t control these higher voltage devices directly, but you can use a 5V relay to switch the 120-240V current and use the Arduino to control the relay.
