ProtoCentral tinyECG – MAX30001 ECG/Respiration module for QT Py / XIAO

ProtoCentral tinyECG is a single-lead ECG & respiration breakout built around the Analog Devices MAX30001 biopotential AFE, shaped to drop onto the back of an Adafruit QT Py or Seeed Studio XIAO microcontroller board. Combined with a QT Py or XIAO and a small LiPo, you have a complete pocket-sized wearable ECG node.

The MAX30001 handles single-lead ECG monitoring with on-chip R-R and pace detection, plus bio-impedance for respiration. tinyECG exposes the SPI lines of the MAX30001 on a QT Py / XIAO compatible footprint.

Note: this module does not include an ECG cable connector. If you need the snap cable and stereo-jack interface, use our full MAX30001 ECG/BioZ breakout instead.

Important notice

This device is not a medical diagnostic instrument. It is intended for evaluation, education, and research only.

Safety

When connecting electrodes to the body, ensure the host computer is running on battery power, not mains. This avoids any direct electrical path between mains earth and the user.
