What is the spiker:bit?​

The spiker:bit allows you to develop DIY Brain Machine Interfaces (BMI) or sometimes called Brain Computer Interfaces (BCI). A BMI is a computers that interfaces directly with the electrical signals of your body. The spiker:bit has a port to connect to a micro:bit (computer), and a port to record from your body.

Technical Specifications​

Power source2x AA Battery
Recording ModesEMG, ECG
Outputs1x Servo, 1x Expansion Port
Inputs1x Orange Electrode Cable

Hardware Overview​

The Spiker:bit has a slot that accepts a V1 or V2 micro:bit. The electrode required for recording is our orange cable with 3 leads (2 recording electrodes and a ground). NeuroBit Top

You can select between EMG (Muscle) or EKG (Heart) or EEG (Brain) within software... no switches needed. A Servo controller is provided on PIN 8. There is also an expansion port on the bottom to get clean access to additional pins for your project, as well as a digital, serial, and analog Grove connectors for adding more human sensors!

What Will You Need?​

To get started, you will need:

  • 3x BYB Large Muscle Electrodes
  • 1x BYB Orange Electrode Cable
  • 1x Spiker:bit
  • 1x micro:bit

Connect the micro:bit to the front slot on the spiker:bit. Be sure that the LEDs are facing outwards. Connect the orange cable to the electrode on the spiker:bit side port.
NeuroBit Connecting

Connect the USB cable from your computer to the micro:bit.
