      • Partnumber : CYBLE-416045-02
      • Datasheet : http://www.cypress.com/file/428336/download

    • CYPRESS Exelon FRAM
      • The Ferromagnetic memory provides an unlimited read/write cycles ; non volatility and low power are the key FRAM technology advantages. High performance QSPI interface provides best performances. They are ideal for critical data logging. We implemented a 4MBit FRAM.
      • Partnumber : CY15B104QSN-108SXI
      • Datasheet : http://www.cypress.com/products/excelon-fram

    • ROHM Motion mems
      • ROHM acquired KIONIX a global MEMS inertial sensor manufacturer. On Sequana, we support many ROHM(KIONIX) motion mems due to the implementation of 2 footprints on the board (2x2mm and 3x3mm). ROHM(KIONIX) have a broad range of consumer grade mems as well industrial derivatives.

        On Sequana, we focussed on the last category enabling machine health, vibration monitoring, profiling & preventive maintenance type of applications.
        By Default, KMX65 is populated enabling a combo 3D magnetometer + 3 accelerometer KMX65 is able to measure ±8g / ±16g / ±32g / ±64g full scale range for the accelerometer and ±200μT / ±400μT / ±800μT / ±1200μT full scale range for the magnetometer.

Import programsequana-rgb-led-example

Example program to blink RGB LEDs on Sequana board in a rotating pattern.

Import programsequana-ble-HeartRate

This is a fork of mbed-os-example-ble-HeartRate maintained for Sequana compatibility. This application transmits a heart rate value using the Bluetooth SIG Heart Rate Profile. The heart rate value is provided by the application itself, not by a sensor, so that you don't have to get a sensor just to run the example. The canonical source for this example lives at https://github.com/ARMmbed/mbed-os-example-ble/tree/master/BLE_HeartRate
