Description
smB1110 BLE PCBA utilizes the Nordic nRF52810-QCAA SoC with a PCB trace antenna.
smB1111 BLE PCBA utilizes the Nordic nRF52811-QCAA SoC with a PCB trace antenna. The nRF52811 BLE
SoC is simply a slightly newer version of the nRF52810 BLE SoC and provides the exact same radio
functionality.
smB1110/smB1111 operates as a ‘Connectable-Beacon’ and transmits its beacon information at a fixed interval
that can be adjusted from 1 to 2.2 seconds and at a Tx power of 0dBm. It can optionally be provided with a
MEMs accelerometer for simple motion detection.
For the nRF52810-QCAA and nRF52811-QCAA SoC, refers to the nRF52810/nRF52811 Product Specification
and the SDK is available from the Nordic Semiconductor website.
