The board can be assembled with any of these chips. ADS1292, ADS1292R and ADS1192 demonstration kits are available. The MSP430 firmware and PC application are designed to automatically detect the installed part and configure to accommodate the part.
1. Four electrode ECG cable support
2. View six ECG Leads: Lead I, Lead II, Lead III, Lead aVR, Lead aVL, Lead aVF and respiration channel (ADS1292R only) .
3. Two modes of operation: Evaluation and Live ECG / Respiration
4. Acquire data at up to 8 kHz in Evaluation mode
5. Current based Lead off detection
6. USB based power and PC application connectivity
7. Access to all ADS1x9x registers via an easy to use GUI.
8. Built-in time domain, histogram, FFT and ECG / Resp related analysis on the PC application
9. Live ECG with heart rate calculation.
10. Live Respiration wave with respiration rate calculation
11. USB based firmware upgrade option
12. MSP430 Firmware debugging using ez430 USB emu
