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.

BMP180 Pressure sensor, BMP180 Product Page and BMP180 Device Driver
SI7020-A10 Humidity sensor, Si7020 Product Page and Si7020 Device Driver
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.
