It is an 8 Channel Isolated 5V 10A Relay Module, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other types of equipment with large current. Relay output maximum contact is AC250V 10A and DC 5V 10A. One can connect a microcontroller with standard interface directly to it. Red working status indicator lights are conducive to the safe use. It has a wide range of applications such as all MCU control, industrial sector, PLC control, smart home control.

So, ready to get switching on your Raspberry Pi?! This neat relay module features 8 x 5V relays rated at 10A/250V each. t is designed to switch up to 4 high current (10A) or high voltage (250V) loads with the help of microcontroller!

Each relay can individually switch to on/off state. It only requires a voltage of approx 1.0V to switch the inputs on but can handle input voltages up to 5V. This makes it ideal for 3.3V & 5V devices.

Specifications and Features:-


  • One normally closed contact and one normally open contact
  • Triode drive, increasing relay coil
  • High impedance controller pin
  • Pull-down circuit for avoidance of malfunction
  • Power supply indicator and Control indicator lamp

PhaseThree Phase
Dimensions Mm20 x 17 x 3 mm (L x W x H)
Humidity90% RH
Weight2 gm
Voltage3.3-5 V

2 Channel Logic Level Converter Module is a Bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices.

What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side. The level converter is very easy to use.
The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.

Rs 190  / PieceGet Best Price
Operating Voltage3.3V
Weight2 gm
Shipment Weight0.105 kg
Shipment Dimensions10 x 8 x 5 cm
Number of Bit16 Bit
Model NumberADS1115
PCB Size28 x 16 mm
This is ADS1115 16-Bit ADC – 4 Channel with Programmable Gain Amplifier. For micro-controllers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-end input channels or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and it’s super easy to use. It is a great general purpose 16-bit converter.
The chip’s fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115’s connect on a single 2-wire I2C bus for 16 single end inputs.
To get you start, we have example code for both the Raspberry Pi (in our Adafruit Pi Python library) and Arduino (in our ADS1X15 Arduino library repository) Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller’s I2C port and run the example code to start reading data.
Features of ADS1115 16-Bit I2C ADC 4-Channel Programmable Gain Amplifier Module:-
  • WIDE SUPPLY RANGE: 2.0V to 5.5V
  • It has an Internal low-drift voltage reference
  • Internal Oscillator.
  • Internal PGA.
  • I2C INTERFACE : Pin-Selectable Addresses.
  • Four single ends Or Two differential inputs.
  • Programmable Comparator.
  • This board/chip uses I2C 7-bit addresses between 0x48-0x4B, selectable with jumpers
  • LOW CURRENT CONSUMPTION: Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut-Down
