About xyz-mIoT shields
itbrainpower.net xyz-mIoT is a 35x45mm IoT shield built around ATSAMD21G ARM0 microcontroller (Arduino Zero compatible design) having embedded LiPO battery charger module, optional embedded THS + tVOC + HALL + IR + tilt/vibration sensors and optional LPWR LTE CATM1 or NB-IoT, 3G or GSM modem.
Driven by the power and versatility of the embedded ARM0 (ATSAMD21G) core and equipped with various interfaces [I2C, SPI, UART, 13 digital I/O - 1WIRE and PWM capable, 5 analog inputs and more - see specifications], "xyz-mIoT by itbrainpower.net" provides multiple interfaces in order to support wide range of devices, sensors and actuators.
As modem capability clasification, four main xyz-mIoT versions are curently commercially available: BG96 [LTE CATM1, NB IoT, 2G and GNSS], BC95G [NB IOT], M95FA [2G] and modemless - all having variants related to embedded sensor(s) integrated, see PN coding. Further more, xyz-mIoT design support other LTE CAT4, LTE CAT1 or 3G modem variants - if you require such variants for specific project, contact us.
The xyz-mIoT shield may have up to 5 built-in sensors such as: THS (temperature and humidity sensors) - HDC2010, tVOC & eCO2 (air quality sensor - CO2 total volatile organic compounds - CO2 equivalent) - CCS811, HALL (magnetic sensor) - DRV5032 or IR (infrared sensor) KP-2012P3C, secondary IR (infrared sensor) - KP-2012P3C, TILT (movement vibration sensor) - SW200D or REED (magnetic sensor). Based on populated sensors, several variants can be ordered using different Part Numbers, see PN coding.
