Wireless Sensor Node
Environmental Sensor
Demo Kit
MAXWSNENV
General Description
The MAXWSNENV demo kit provides a convenient
platform evaluating the capabilities of the environmental
sensor version of Maxim’s wireless sensor node (WSN).
The kit provides an excellent foundation for the Internet of
Things (IoT) applications.
The WSN board includes a microcontroller, BLE trans-
ceiver, multiple environmental sensors and coin-cell
holder. The WSN kit also includes a programming adapter
compatible with the ARM mbed HDK specification.

Demo Kit
MAXWSNENV
Bluetooth is a registered trademark of Bluetooth SIG, Inc.
Detailed Description
This demo kit is general purpose in nature, however, the
included sensors allow for the development of sophisti-
cated wireless sensor network and IoT nodes. This sec-
tion describes each major function or component on the
MAXWSNENV board.
Use the MAXWSNENV board with the following separate
documents:
●MAXWSNENV data sheet (this document)
●MAX32600 data sheet
●MAX32600 user guide
●MAXWSNENV board schematic
●MAXWSNENV board bill-of-materials
Board Power
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.
LEDs
A single, tri-color LED with series resistors is connected to
GPIO pins P1.4, P1.6, and P1.7.
