Board Power

The demo board is powered by on-board coin-cell battery or by a connected and powered MAXHDK.

Bluetooth Low Energy (BLE) controller

The Bluetooth Low Energy controller is Bluetooth V4.0 compliant.

Sensors

The MAXWSNENV is fitted with four environmental sensors. 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.

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.
