Neuro PlayGround Lite (NPG Lite) is a multichannel Adafruit feather form-factor wireless bio-physiological signal acquisition board.
It can be used for Electrocardiography (ECG), Electromyography (EMG), Electrooculography (EOG), or Electroencephalography (EEG). Its compact footprint and hassle-free setup ensure portability, quick deployment and a clutter-free experience, making it ideal for research, education and wearable applications.

With the addition of Playmate boards (Proto Playmate, VibZ Playmate and VibZ+ Playmate) and 3rd party FeatherWing boards, users can easily enhance the device’s capabilities, enabling them to create awesome Human-Computer Interface (HCI) and Brain-Computer Interface (BCI) applications. Its extensive compatibility lets you equip your device with features like a vibration motor for haptic feedback, a buzzer for audio feedback, and I2C connectivity, making it highly versatile for a wide range of applications.

It leverages our powerful open source, cross-platform Chords software suite (Chords-Web, Chords-Python, Chords LSL Connector and NPG Lite Flasher), letting users visualize captured bio-physiological signals in real-time, apply filtering, perform FFT analysis, and much, much, more. Because of its expandability, wide array of applications, and robust networking capabilities (using Bluetooth, Zigbee, Wi-Fi, or Thread for mesh networking), NPG Lite lets you capture bio-physiological signals how you want and where you want it.

Board Layout & Pinout Diagram

Playmates

Playmates are modular expansion boards designed to enhance the functionality of Neuro PlayGround (NPG) Lite. These add-ons seamlessly integrate with the core system, allowing users to extend their capabilities to create awesome Human-Computer Interface (HCI) & Brain-Computer Interface (BCI).

NPG Lite Playmates are add-on boards that expand the functionality of the NPG Lite system.

• The Proto Playmate includes a prototyping area, electrode connector interface, ON/OFF slide switch, and a QWIIC port.
• The VibZ Playmate adds haptic and auditory feedback via a vibration motor and buzzer, along with an electrode connector interface, ON/OFF slide switch, and QWIIC port.
• The VibZ+ Playmate builds on the VibZ by adding an additional 3-channel BioAmp, enabling a total of 6 channels. It is designed for applications that require higher-resolution biosignal input or more spatial coverage.
