SIDK S1SBP6A Bio-processor dev kit

S1SBP6A supports various health signals such as ECG, PPG and BIA with a single chipset

Available on Q1, 2021


Overview

S1SBP6A supports various health signals such as ECG (Electrocardiography), PPG (Photoplethysmography) and BIA (Bioelectrical Impedance Analysis) with single chipset.
All the health signals can be achieved simultaneously and it can process the various signals within S1SBP6A sensor hub by using powerful Cortex-M4F processor (102.4MHz).
his sensor hub has 2MB of flash memory and 256KB of SRAM for fast algorithm calculations.

The Samsung Bio-processor platform SIDK has been designed for users to develop wellness or medical devices easily.
Based on Samsung S1SBP6A sensor hub, the board provides an extensive set of sensors like PPG module, temperature and 6-axis that can be used as building blocks for health application.

nRF52833 BLE chipset is utilized to transmit health data to the mobile phone or other wireless devices.

The Samsung Bio-processor platform SIDK also provides ArduinoTM UNO V3 compatible headers, enabling plug and play of various shield boards.

It comes with an on-board debugger/programmer (DAPlink) to easily debug and program the S1SBP6A.
