Raspberry Pi Foundation created a transformation on the market among individuals in the direction of the modern technology. There are a great deal of people who are making use of Raspberry Pi products in their tasks, gizmos, and also robotics to make it a lot more efficient. There are enthusiasts, tech-enthusiasts, students, etc that enjoy to work on Raspberry Pi to evolve the innovation for a better future. Some individuals desire to increase the features of their jobs along with Raspberry Pi further for which they utilize HAT or Hardware Attached on Top. SB Components has a Research and Development department that establishes sophisticated HAT for Raspberry Pi amongst which Power Monitor HAT is the newest arrival in the marketplace. In this blog, we’ll look right into the details of Power Monitor HAT to give all the essential info for individuals.

Power Monitor HAT

As the name recommends, Power Monitor HAT permits the user to keep track of existing, voltage, or power in each channel. One of things that Raspberry Pi customers want to have is a gadget where they can gather the value of existing or voltage. SB Components consider the void of that product on the market for the customers as well as created Power Monitor HAT. Power Monitor HAT is a 3 Channel Current/Voltage/Power Monitor HAT For Raspberry Pi. Power Monitor HAT is developed for light-weight interaction by means of the I2C or SMBus user interface which makes an increment in the high quality of the item. It does not just make the process very easy of keeping an eye on the existing, voltage, or power in each channel but likewise makes things interesting for the individuals. One can likewise keep an eye on the voltage between both sides of the sampling resistor that includes a crucial attribute to it.

Power Monitoring HAT for Raspberry Pi

Specifications Running voltage: 3.3 V/5V Control interface: I2C/SMBus

  • Experiencing resistor: 0.1 Ω 1%
  • Voltage variety: 0 ~ 26V DC
  • Existing variety: ± 3.2 A
  • Resolution: 0.8 mA ( ± 3.2 An array)
  • OR 0.1 mA (± 400mA array) Dimensions: 65mm × 30mm


  • It has the conventional Raspberry Pi 40PIN GPIO extension header from which it can be stacked on Raspberry Pi conveniently. It sustains all the variants of Raspberry Pi boards.
  • Power Monitoring HAT consists of an Embedded ADC of 12 little bits that convert the analog signal into an electronic signal. Power tracking HAT is created to sustain multiple successive transforming with the 0 ~ 26 DC voltage determining range.
  • There is a tasting resistor that is onboard, 0.1 Ω 1 % permits gauging bi-directional current up to 3.2 A in the channel.
  • It offers the tracking on 3 channels. It executes the job through the I2C/SMBus interface that makes the process take place on the low bandwidth.
  • It can directly determine electric amounts like power, voltage, as well as present. Power Monitoring HAT procedures result power value with an extra increase register that helps the user to get the appropriate readings.
  • Power Monitor HAT is composed of I2C control pins for getting in touch with various other host boards to do the job according to the need.

Steps to mount Power Monitor HAT

These are the following ways that one can comply with to install and run Power Monitor HAT

  1. Initially make it possible for I2C interface by running “sudo raspi-config” command then choose interfacing alternatives >> > > I2C > > click enter to enable it.
  2. You can likewise make use of GUI to make it possible for i2c, click Menu > > Preferences > Raspberry Pi Configuration > > interfaces, Then enable I2C
    Raspberry Pi Configuration
  3. Open Terminal and install reliance needed to run power surveillance HAT. sudo pip3 mount adafruit-circuitpython-ina219
  4. Currently Clone database and run instance code.

git clone

cd Power-Monitor-HAT

cd RaspberryPi
