RHD2216 Arduino Shield
The RHD2216 Arduino shield (Part #C3601) monitors low-frequency biopotential signals
(typically EMG or ECG) from two low-noise amplifier channels using the
RHD2216 digital electrophysiology chip
from Intan Technologies. An Arduino Uno microcontroller (not included) is connected to the
shield and communicates to a computer over a USB interface. Free open-source Arduino C++ software from Intan
allows users to monitor two biopotential signals and use activity on these channels to trigger sound cues and
The RHD2216 Arduino Shield has the following features:
- Included software implements a 1 kHz per channel sampling rate on two amplifier channels, suitable for
EMG and ECG signals.
- Easy access to two amplifier channels through 3.5-mm phone jacks. Electrode leads with snap connectors
- CMOS-level SPI bus communication with Intan RHD2216 amplifier chip.
- Solder holes offer access to an additional 14 amplifier channels and other auxiliary I/O.
- On-board two-channel digital-to-analog converter (DAC) can reconstruct analog waveforms from two
amplifier channels in real time with sub-millisecond latency.
- On-board configuration switches select 50/60 Hz notch filter operation, audio output, and total gain.
- Activity detection digital output pins indicate when the input signal level is above a user-selectable
