This sec- Component List and Schematic tion describes each major function or component on the MAXWSNENV board. Refer to the following files attached to this data sheet for component information and schematic: Use the MAXWSNENV board with the following separate documents: MAXWNENV BOM.xls MAXWSNENV data sheet (this document) MAXWNENV Schematic.pdf MAX32600 data sheet MAX32600 user guide Ordering Information MAXWSNENV board schematic PART TYPE MAXWSNENV board bill-of-materials MAXWSNENV Demo kit Board Power Denotes RoHS compliant. The demo board is powered by on-board coin-cell battery or by a connected MAXHDK. Bluetooth Low-Energy (BLE) Controller The Bluetooth low-energy controller is Bluetooth V4.0 compliant. Sensors The MAXWSNENV is fitted with four environmental sen- sors. Digital sensors are connected to the MAX32600 I2C master interface. Analog sensors are connected to the MAX32600 ADC interface. The MAXWSNENV includes the following sensors: BMP180 pressure sensor SI7020-A10 humidity sensor RPM-075PTT86 phototransistor NPN diode temperature sensor Pushbuttons Pushbutton SW1 can be used to generate an input for test purposes on port pin P1.5. SW1 is normally open, and therefore, provides a logic 0 when depressed. Firmware defines the action taken on this switch closure. Pushbutton SW2 provides a power-on-reset function to the MAX32600 microcontroller. USB The MAXWSNENV board provides access to the MAX32600 USB D+ and D- signals on connector J1 pins 16 and 18, respectively. Bluetooth is a registered trademark of Bluetooth SIG, Inc.
