+## Description
+
+**CoreInk** is a brand new E-ink display in the M5Stack cores range. Controlled by the ESP32-PICO-D4 This new device includes a 200x200 1.54" Black and White E-Ink Display. Compared to a regular LCD,E-ink displays are easier on the eyes, which makes them a great choice for reading or viewing for longer periods. Other benefits are the low power consumption and the ability to retain the image even if power to the display is terminated。For control the CoreInk integrates an multi-function button,A physical button, integrated status LED and buzzer.The device also includes a 390mAh Lipo,RTC(BM8563)for controlling accurate timing and deep sleep funcionality. CoreInk features independent reset and power buttons,expansion ports(HY2.0-4P、M-BUS、HAT expansion)for attaching external sensors to expand functionailty,for unlimited possibilities。
+
+?>Warning: Please avoid using high refresh rates,reccommended refresh rate is(15s/per refresh), Do not expose to ultraviolet rays for a long time, otherwise it may cause irreversible damage to the ink screen.

+# ECG Module13.2 (AD8232)
+
+SKU:M034
+
+
+
+## Description
+
+**ECG** is a heart rate monitor (electrocardiogram) unit,it can detect the heart rate and output a cardiogram signal. Electrocardiogram (ECG) is a technology that uses an electrocardiograph to record the changes in the electrical activity of the heart during each cardiac cycle. At the signal acquisition end, this ECG module integrates the AD8232 single-lead heart rate monitoring at the front end, the collected ECG signal is processed by the AD8603 low-pass filter, and the 10bit-ADC (AD7476) performs analog/digital signal input to STM32 (built-in heart rate statistics) Algorithm) for signal analysis. Finally, the processing results are output in the form of serial communication to facilitate the acquisition and display of the main control device. In terms of signal output, it adopts front-end/digital full isolation design to enhance equipment stability and safety.
+
+?>Caution: This product only allows the use of `5V` power input. Please strictly abide by the power input standard when using this product to avoid damage to the equipment or injury.
+
+
