PCA10001 Power consumption

Dani

Good afternoon,

I'm trying to test PCA10001 eval board power consumption and consumption is about 4mA when it should be considerably lower. To proceed with this measurement I have first cut the SB8 soler bridge and I use an ampere-meter between pin 1 and 2 of P1. Furthermore, after flashing the board, I have switched it off and I have set SW4 to OFF position to switch off J-Link. I have tried with several demos (last one is 'ble_app_hrs') and I still have 4mA power consumption: I switch on board (I have tried with external battery and with USB) and I wait it to finish advertising time to go to system-off mode. In system-off I have these 4mA!!! Do you know which is the problem? Thanks!

    Hi

    Try the system-on-gpio example provided here. You should measure about 3uA current with this example when you have pressed button 0 in order to enter System On low power mode. To make the KEIL project compatible with the PCA10001 kit, replace the BOARD_NRF6310 constant define in the Keil project to BOARD_PCA10001 image description

    Update 27.8.2014: To accurately measure current you need to disconnect the debugger/programmer and any external circuit connected to the GPIO, in order to prevent potential current leak. For the PCA10001 board of the evaluation kit, disconnect the debugger by setting switch SW4 to OFF
