Delta DFCM-NNN50

Delta DFCM-NNN50 Development Platform is CE, FCC, TELEC and Bluetooth EPL logo approved EVB that base on NORDICSemi nRF51822 ARM Cortex-M0 SoC with embedded IEEE 802.11 b/g/n Wi-Fi chipset. The developed platform supports ARM mbed toolchain and Arduino form factor.


The Delta DFCM-NNN50-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 Arduino Uno Revision 3 standard so various 3rd-party sensing, control capability shields can interface with BLE/Wi-Fi combo module on daughter board for rapid prototyping BLE and Wi-Fi applications.

The module is based NORDICSemi nRF51822 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) and WIFI CLI which allow external host MCU to control and set BLE and Wi-Fi communication through UART. The CLI running on the module handles all the BLE and Wi-Fi protocol tasks ends up the application is left to be implemented on external host MCU with minimal development overhead.



WARNING: Note that AnalogIn A4, A5 must remain not connected since those two pins are currently used for 32.768kHz RTC
