Nrf52 totem pole output6/23/2023 ![]() ![]() The nRF52 DK supports programming and debugging nRF51 and nRF52 devices mounted on external boards. The Debug in connector ( P18) makes it possible to connect external debuggers for debugging while running on battery or external power supply. The nRF52 DK is equipped with a small size coaxial connector ( J1) for conducted measurements of the RF signal. The current drawn by the nRF52832 device can be monitored on the nRF52 DK. NRF52832 can use an optional 32.768 kHz crystal (X2) for higher accuracy and lower average power consumption. The four buttons and four LEDs on the nRF52 DK are connected to dedicated I/Os on the nRF52832 chip. The P1 connector provides access to ground and power on the nRF52 DK. The nRF52 DK has three power options: 5 V from the USB, external power supply, and coin cell battery.Īccess to the nRF52832 GPIOs is available from connectors P2, P3, P4, P5, and P6. The nRF52 DK block diagram shows the connections between the different blocks. NRF52 DK hardware drawings show both sides of the PCA10040.
