Digital Signals
The ADS1298R digital signals (including SPI interface signals, some GPIO signals, and some of the
control signals) are available at connector J3. These signals are used to interface to the MMB0 board
DSP. The pinout for this connector is given in

Analog Input Signals
The ADS1298R provides users the option to feed in standard ECG signals from a patient simulator to the
DB15 connector, or to feed inputs from any arbitrary signal source directly to the ADS1298R.
