There are two buttons (RST, -KEY), two LED’s (Pin 30, 31), a voltage regulator and a current measurement shunt -on board. A serial connection and flashing must be provided by external -Hardware. -The nRF52832 is a SoC with a 32-bit ARM® Cortex™-M4F CPU with 512KiB Flash and -64KiB RAM. The embedded 2.4GHz transceiver supports Bluetooth low energy, ANT and -proprietary 2.4 GHz protocol stack. It is on air compatible with the nRF51 -Series, nRF24L and nRF24AP Series products from Nordic Semiconductor. +The +[nRF52 DK](https://www.nordicsemi.com/Products/Development-hardware/nRF52-DK) +is a development board featuring the nRF52832 MCU with Arduino compatible +pin headers and an integrated J-Link programmer, debugger and UART adapter. ## Hardware: -![nRF52 minimal development -board](https://github.com/d00616/temp/raw/master/nrf52-minidev.jpg) -| MCU | NRF52832 | -|:----------------- |:------------------------------------------------------------------------------------- | -| Family | ARM Cortex-M4F | -| Vendor | Nordic Semiconductor | -| RAM | 64KiB | -| Flash | 512KiB | -| Frequency | 64MHz | -| FPU | yes | -| Timers | 5 (32-bit) | -| RTC | 3 | -| ADCs | 1x 12-bit (8 channels) | -| UARTs | 1 | -| SPIs | 3 | -| I2Cs | 2 | -| I2S | 1 | -| PWM | 3*4 Channels | -| Radio | 2.4GHz BLE compatiple, -20 dBm to +4 dBm output, -96 dBm RX sensitivity | -| Vcc | 1.7V - 3.6V | -| Datasheet | [Datasheet](https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF52832) | -| Reference Manual | [Reference Manual](https://infocenter.nordicsemi.com/pdf/nRF52832_PS_v1.4.pdf) | +![nRF52 DK](https://www.nordicsemi.com/-/media/Images/Products/DevKits/nRF52-Series/nRF52-DK/nRF52-DK/nRF52-DK-prod-page.png) -##Pin layout - -|MCU pin|Board pin|Function| -|:-----------|:-----------|:----------| -|P0.0| n.c. | | -|P0.1| n.c. | | -|P0.2| D07 | | -|P0.3| D08 | | -|P0.4| D09 | KEY | -|P0.5| D10 | | -|P0.6| D13 | | -|P0.7| D14 | | -|P0.8| D15 | | -|P0.9| n.c. | | -|P0.10| n.c. | NFC antenna 2 (unusable) | -|P0.11| D18 | RXD (software defined) | -|P0.12| D19 | TXD (software defined) | -|P0.13| D20 | | -|P0.14| D21 | | -|P0.15| D22 | | -|P0.16| D23 | | -|P0.17| D24 | | -|P0.18| D25 | | -|P0.19| D26 | | -|P0.20| D27 | | -|P0.21| RST | RESET | -|P0.22| D28 | near Radio! -> Low drive, low frequency I/O only. | -|P0.23| D29 | near Radio! -> Low drive, low frequency I/O only. | -|P0.24| D30 | near Radio! -> Low drive, low frequency I/O only. | -|P0.25| D00 | near Radio! -> Low drive, low frequency I/O only. | -|P0.26| D01 | near Radio! -> Low drive, low frequency I/O only. | -|P0.27| D02 | near Radio! -> Low drive, low frequency I/O only. | -|P0.28| D03 | near Radio! -> Low drive, low frequency I/O only. | -|P0.29| D04 | near Radio! -> Low drive, low frequency I/O only. | -|P0.30| D05 | LED0, near Radio! -> Low drive, low frequency I/O only. | -|P0.31| D06 | LED1, near Radio! -> Low drive, low frequency I/O only. | -| | V33 | 3.3V for MCU | -| | D16 | ? | -| | D17 | ? | -| | VBUS | 5V input | -| | GND | | -| | RXD | n.c. | -| | TXD | n.c. | -| | TD0 | n.c. | -| | TD1 | n.c. | -| SWDIO | TMS | | -| SWCLK | TCK | | - -**Caution**: NFC is not usable with this board. +| MCU | NRF52832 | +|:--------------------- |:------------------------------------------------------------------------------------- | +| Family | ARM Cortex-M4F | +| Vendor | Nordic Semiconductor | +| RAM | 64 KiB | +| Flash | 512 KiB | +| Frequency | 64 MHz | +| FPU | yes | +| Timers | 5 (32-bit) | +| RTC | 3 | +| ADCs | 1x 12-bit (8 channels) | +| UARTs | 1 | +| SPIs | 3 | +| I2Cs | 2 | +| I2S | 1 | +| PWM | 3*4 Channels | +| Radio | 2.4GHz BLE compatiple, -20 dBm to +4 dBm output, -96 dBm RX sensitivity | +| Vcc | 1.7V - 3.6V | +| MCU Datasheet | [Datasheet](https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF52832) | +| MCU Reference Manual | [Reference Manual](https://infocenter.nordicsemi.com/pdf/nRF52832_PS_v1.4.pdf) | +| Board Datasheet | [User Guide](https://infocenter.nordicsemi.com/pdf/nRF52_DK_User_Guide_v1.3.1.pdf) | ### RESET pin configuration
