Product Description
PSLab is a small USB powered hardware extension for your Android phone or PC that lets you
measure all kinds of things. PSLab comes with a built-in Oscilloscope, Multimeter, Wave
Generator, Logic Analyzer, Power Source, and we are constantly adding more digital instruments.
PSLab is many devices in one. Simply connect two wires to the relevant pins and start measuring.
You can use our Open Source Android or desktop apps to view and collect the data. You can also
plug in hundreds of compatible I2C standard sensors to the PSLab pin slots. It works without the
need for programming. So, what experiments you do is just limited to your imagination! PSLab is
developed by FOSSASIA and OpnTec in collaboration with a global community of Open Source
developers.

Applications
PSLab is a scientific device for measurements. Application areas range from physics and
electronics experiments and measurements to biological and chemicals measurements. You are
student or scientist and want to conduct experiments, a hardware developer designing new
devices, or a technician fixing digital electronic devices? Use PSLab!
USB Powered / OTG Data Connection with Phone or PC
Pocket Science Lab is directly powered through the USB connection. It doesn’t need any other
external power source. All you need to do is to attach it to the phone via a USB OTG cable if you
are using the mobile app or directly to your laptop’s USB port if you are using the desktop app.
WiFi and Bluetooth
PSLab has slots for ESP and Bluetooth chips. The functionalities are already implemented in the
firmware. Solder the chips to the dedicated slots. For the WiFi functionality also don’t forget to
install the relevant packages on the ESP WiFi chip and you are ready to go. Devices can be
powered through an external battery when they are accessed through Bluetooth or WiFI.
