Delta DFBM-NQ620

Delta DFBM-NQ62X Development Platform is CE, FCC, TELEC and Bluetooth EPL logo approved in which, it is used for Bluetooth Smart, ANT and 2.4GHz proprietary radio and NFC tag development based on NORDICSemi nRF52832 ARM Cortex-M4F SoC with ARM mBedOS5.X. This board is also compatible with nRF52-DK with low power regulator setup


The Delta DFBM-NQ620-EVB contains a mbed compatible HDK mother board and a daughter board mounted with CE/FCC/TELEC and Bluetooth EPL certified BLE module. The mother board is designed to compatible with I2S, Arduino Uno Revision 3 standard so various 3rd-party audio, sensing, control capability shields can interface with BLE with NFC Tag module for rapid prototyping BLE applications.

The module is based NORDICSemi nRF52832 SoC therefore it supports the standard Nordic Software Development local compiler using Keil, IAR and GCC as well as ARM mbed online compiler for embedded standalone application development. The module also supports Delta defined BLE CLI (Command Line Interface) which allow external host MCU to control and set BLE communication through UART. The CLI running on the module handles all the BLE protocol tasks ends up the application is left to be implemented on external host MCU with minimal development overhead.
