在Nordic官网上可以除了有芯片的设计参考之外,Nordic的官方DK(Development Kit)的设计资料也是全开源的,可以在官网上找到。 我们以nRF52840为例,首先进入Nordic官网:https://www.nordicsemi.com。 点击右上角搜索芯片,在这里可以搜到芯片和对应DK的相关页面。我们搜索nRF52840,可以看到在这里搜到了nRF52840 Dongle、DK...
Normal Voltage mode on nRF52840, with only LDO enabled Only DEC4 is mentioned on the schematic above. I am particularly interested by the DEC pins (DEC1, DEC2 until DEC6), where external decoupling capacitors are connected. NordicSemiconductor does not provide any detail about the nRF52 power...
Since long time I am fighting to lower power consumption using this library to the levels reachable with Sdk examples! I have run several examples, testing the uA level in different type of code. If we don't use BLE libraries uA are very near to the one expected , normally few uA when...
Results on nRF58232 Tests are achieved on thenRF52-DK, based onnRF52832. The development board is modified by removing capacitors and soldering wires: nRF52832 reference schematic nRF52832 thin wire soldered to DEC1, red wire to DEC4. Note: only the thin wire connected to DEC1 is sufficie...
