Delta DFCM-NNN40 (EOL)

Delta DFCM-NNN40-EVB provides prototype board for ARM Cortex-M0, BLE and Wi-Fi function. The developed platform supports ARM mbed toolchain and Arduino form factor.


The Delta DFCM-NNN40-EVB is a development board with combo module which combines with Bluetooth Low Energy (BLE) and Wi-Fi technology designs. BLE use Nordic nRF51822 SoC and Atmel SmartConnect Wi-Fi solution, which contains Bluetooth Low Energy-compliant 2.4GHz multiprotocol radio and ARM® Cortex®-M0 processor; Additionally, Delta DFCM-NNN40 kit has Wi-Fi solution with ultra-low power IEEE 802.11 b/g/n. It is a highly integrated platform to implement application when Wi-Fi and/or BLE connection is considered. Delta DFCM-NNN40-EVB also provides rapidly developed platform. The hands-on application can be generated from mbed online IDE and use USB drag-and-drop method to load application to Delta DFCM-NNN40. Besides, NNN40-EVB has mounted temperature/humidity sensor (PN: HTS221), the library and example application is available in mbed. The BLE and Wi-Fi API are also enabled in mbed SDK. Besides, the HDK support USB CMSIS-DAP, CDC, MSC (for DnD) function. The module could be controlled more quickly with the above feature.


Delta DFCM-NNN40-EVB has pin out for SPI, I2C, UART, ADC and GPIO pin. It is included the specific pin out such as RF switch (switch radio antenna to Wi-Fi or BLE) PIN and SWD PIN. The detail is described in the mbed Delta DFCM-NNN40 getting started.

Note that following pinout image only refer to EVB Ver.03 which is the MP version of this platform
