DA14531 Image

The SmartBond TINY DA14531 from Dialog Semiconductor is a Bluetooth Low Energy Module with an integrated antenna. Based on a Bluetooth 5.1 SoC, this module is optimized to significantly reduce the cost of adding BLE functionality to an IoT system. Its easy-to-use design and software allow developers to quickly and intuitively develop highly functional connected devices, targeting the next generation of the connected consumer, connected medical, smart home, and smart appliance applications. The module delivers 2.2 dBm of output power and has a sensitivity of -93 dBm It requires supply from 1.8 to 3.3V. The DA14531 integrates a 4-channel 10-bit ADC, an ARM Cortex-M0+ microcontroller with 48 KB of RAM, 1 MB FLASH, and a One-Time Programmable (OTP) memory of 32 kB.

This DA14531 module incorporates two unique software features to eliminate the complexity of BLE development. The first is the configurable Dialog Serial Port Service (DSPS) software, which emulates a universal asynchronous receiver-transmitter (UART) serial port over BLE, removing the need to write Bluetooth software for ‘BLE Pipe’ applications when connecting the module to a host MCU’s serial port. The second feature, Dialog’s new Codeless software, which replaces complex code with a simple series of human-readable ASCII commands that can be used to generate customer applications. Codeless uses the industry-standard Hayes AT-style command set to configure and operate the module.

This hand solderable stamp type TINY module offers 9 GPIO’s and measures 12.5 x 14.5 mm with 2xUART, SPI, I2C interfaces, integrating all external components, including passives, XTAL, antenna, and FLASH memory. The module is fully certified for worldwide operation, with FCC certification for the Americas and CE certification for Europe. It is suitable for beacons, remote controls, proximity tags, toys, and low power sensors applications. This DA14531 is compatible with any equipment providing ease of use with smartphone app-based based setup and control, eliminating the need for printed user manuals.
