From the project
An all-in-one kit to deploy and test ECG algorithms with ease. Based on the AD8233 and S1 Module, this open source board is a great for new products, as well as research and teaching.
- Single chip frontend based on the AD8233 - S1 Module with Bluetooth 5.2 and FPGA - Integrated lithium battery - Ultra low power auto-sleep down to 175uA - Open source design
- Learning and teaching around heart health - Research of ML based ECG algorithms - Wireless ECG data logging - New product development
A powerful analog frontend combined with the S1 Module makes this an all-in-one kit to deploy and test algorithms with ease. Be that for learning, research, or as the starting point for your next product.
