Bluetooth LE module (UTO-NBL-52A) User Manual

1. Product Information

UTO-NBL-52A is an antenna-embedded low-power Bluetooth module.
UTO-NBL-52A is a module that integrates wireless circuit, software stack and
antenna for Bluetooth operation.
It is a function that can operate independently without the need of a separate
external control device.
UTO-NBL-52A is applicable to Bluetooth wireless data communication for low power.
It has optimal RF performance with transmit power up to +4 dBm and receive
sensitivity of -93 dBm.

2. Description of operation

UTO-NBL-52A is a product using Bluetooth Low Energy Technology. The product is
operating 2.4GHZ ISM frequency band and it provides a fully compliant Bluetooth
specification system integrates all features of Bluetooth radio, software stack, GATT
based profiles, Antenna and host end user applications, which means no external
micro controller. It provides a Bluetooth Low Energy fully compliant system for a data
communication. The product integrates NordicnRF52832 Bluetooth chipset, 32 MHz
main clock oscillator, 32.768 KHz RTC clock oscillatorand Antenna. RF signal is sent
and received through Antenna.
The product is operated with 1.7 ~ 3.6V external voltage. The product has 30 PIOs.
The PIOs are functions with UART, ADC, I2C, SPI, I2Sand General purpose IO.
Main core is ARM Cortex-M4. The processor implements several features that
enable energy efficient arithmetic and high-performance signal processing including
“digital signal processing”, “Single-cycle multiple and accumulate instructions”,
“hardware divide”, “8 and 16 bit single instruction multiple data instructions”
