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.
Main Features
- Complete Bluetooth® low energy SoC (4.2 specification)
- 32-bit ARM Cortex-M4F processor @ 64MHz
- Size : 32pin QFN 5x5x0.85mm
- Operating Frequency : 2,402MHz ~ 2,480MHz
- Up to 24kB SRAM and 192kB Flash
- Certified for FCC and Bluetooth
- Rx sensitivity : Typical -93dBm
- Operational Temperature range : -20°C to 70°C
Applications
- Asset Tracking
- Remote Monitoring
The (Family model smB1110/smB1111) two models of Main Board share the same PCB layout.
The only difference is the SMB1111 uses a slightly newer BLE SoC in the nRF52811-QCAA.
⚫ smB1110 uses the nRF52810-QCAA BLE SoC
⚫ smB1111 uses the nRF52811-QCAA BLE SoC
