Overview UM-1
1.2 Bluetooth® Microprocessor Nordic nRF52832
The nRF52832 is an ultra-low power 2.4 GHz wireless system on chip (SoC) integrating
the nRF52 Series 2.4 GHz transceiver and an ARM Cortex-M4 CPU with 512kB flash
memory and 64kB RAM.
See the nRF52832 datasheet [1] for more detailed information on device functionality,
electrical specifications and typical performance.
1.3 Power Supply and Power management
The power management circuit consists of a switch mode regulator. It is a buck converter
or step down converter. The input voltage to the UM-1 can be in the range 2.8V to 3.6V.
Outputs from the converter provides 1.8V which is required by the DW1000 [2] transceiver.
1.4 Three Axis Motion Detector
The LIS2DH12 is an ultra-low-power high performance three-axis linear accelerometer with
digital I2C/SPI serial interface standard output. The LIS2DH12 has user selectable full scales
of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1
Hz to 5.3 kHz. The self-test capability allows the user to check the functionality of the sensor in
the final application. The device may be configured to generate interrupt signals by detecting
two independent inertial wake-up/free-fall events as well as by the position of the device itself.
The LIS2DH12 is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
See the LIS2DH12TR Datasheet [4] for more detailed information on device functionality,
electrical specifications and typical performance.
1.5 Software on board
The UM-1 module comes loaded with embedded firmware which provides two-way ranging
(TWR), D7A over UWB communication and BLE (tap-to-connect, beaconing and sniffing in
Eddystone and IBeacon format) functions. The module can be configured and controlled via its
API, accessible thorough its serial (UART or SPI) port. The API is based on the open ALP
specification, elaborated by the D7A Alliance [6]. For further information, contact WizziLab.
The same firmware is also available as a stand alone, non modifiable library, which provides a
function API. This allows to execute the host firmware directly on the MCU of the UM-1.
