Board OverviewThe up2net Sensor DwaRF was designed to stack underneatheither the up2net BLE DwaRF or up2net LoRa DwaRF RFmodules. It comes in a 38.1 x 27.9 mm form factor, which isslightly smaller than the up2net BLE/LoRa DwaRFs. This isdue to the recommended antenna keep-out areas of theBLE652 and RM186/191 modules.

The up2net Sensor DwaRF provides basic environmentsensors (temperatur and ambient light) plus push-button andLEDs for basic control and status indication.

Battery

A standard CR2450 coin-cell can be used to power both the up2net Sensor DwaRF as well as the stacked up2net BLE/LoRa DwaRF for stand-alone operation.

Temperature Sensor

A TMP36 temperature sensor is used for temperature measurement. It provides an analog voltage output, which can be sampled by an BLE652 or RM186/191 ADC input. See sensor data sheet for details:

http://www.analog.com/media/en/technical-documentation/data-sheets/TMP35_36_37.pdf

Ambient Light Sensor

Ambient light is measured by an AMS302 ambient light sensor with analog output signal. The output signal can be sampled by an BL652 or RM186/191 ADC input. See sensor data sheet for details:

https://industrial.panasonic.com/cdbs/www-data/pdf/ADD8000/ADD8000CE2.pdf

Push Button

A push-button is available as digital input of the BL652/RM186/191 module. The signal is shorted to GND, hence a pull-up has to be enabled at the digital input.

LEDS

One red and one green LEDs can be controlled by two digital output signals of the BL652/RM186/191. The LEDs are 2mA low-current devices and a 470 Ohm series resistor is included, which is suitable for 3V or 3.3V operation. Driving the digital output signals high will turn on the LEDs.

Expansion Headers

The analog sensor output signals and push-button / LED signals are connected to pin headers, which mate to the up2net BLE/LoRa DwaRF pin headers. See „Pinout and Dimensions“ for signal location.

Power Supply

The up2net Sensor DwaRF provides a CR2450 coin-cell battery clip, which can be used as power source for stand-alone applications, i.e. BLE or LoRa sensor TAG.

During application development or programming, it‘s necessary to connect the BLE or LoRa DwaRF to a PC, most likely through a USB UART converter, like our ioMate-USB module. In most cases, the BLE/LoRa DwaRF is powered through USB then. If so, jumper J1 has to be removed to disconnect the battery from the USB power. The same applies if the BLE/LoRa DwaRF is powered externally.

Configuration Jumpers

The up2net LoRa DwaRF provides five configuration jumpers, which arecarried out as solder-bridges (J1-J4, needs to be closed by a small dotof solder) or pin-header (J5).

J1: Close to enable power from coin cell

J2: Close to connect power to RM186 LoRa VCC when using up2netSensor DwaRF with the up2net LoRa DwaRF on top.

See picture right for location of the two jumpers.



Board AssemblingThe up2net Sensor DwaRF comes as complete kit withPCB and components. All components are normalthrough-hole-technology components, hence no specialSMT soldering skills or equipment is necessary.

The CR2450 battery is not included due to carrierexport/shipping restrictions.

Populating and Soldering

The picture right shows the locations of the components(PCB silk screen).

Populating is usually done from bottom to top, i.e. westart with the lowest components, like resistors, followedby the jumper pins, LEDs, the sensors, push-button, battery clip up to the pin headers.

We recommend to use lead-free SnAgCu solder with halogen-free no-clean flux.

Stacking with up2net BLE/LoRa DwaRF

The up2net Sensor DwaRF was designed to stack with an up2netBLE or LoRa DwaRF.

Even though the sequence is basically not fixed, in most cases theup2net Sensor DwaRF will be stacked underneath the BLE/LoRaDwaRF. This results in a most flat package and still gives access toall configuration jumpers and USB of the BLE/LoRa DwaRF.

The picture right shows an up2net BLE DwaRF stacked on top ofthe up2net Sensor DwaRF.

Design and Handling PrecautionsThis module – just like any other semiconductor devices – is susceptible to damage by ESD. Suitable precautions should be taken when handling and transporting devices. The possible damage to devices depends on the circumstances of the handling and transporting, and the nature of the device. The extentof damage can vary from immediate functional or parametric malfunction to degradation of function or performance in use over time. Devices suspected of being affected should be replaced.
