Hello,
We have the custom board with nRF54H20. The VDD_EXT pin is used to power some GPIO ports of nRF54H20 (P1/P2/P7).
The voltage we see on VDD_EXT is about 1.3V instead...
Hi,
I want to test the behavior of Enhanced Multi-Admin added in Matter 1.4.
Is it possible to verify this behavior using a Nordic DK board, sample code and a Raspberrypi...
I’m writing BLE UART code. When BLE is not connected, current consumption is ~30 µA. But when BLE is connected, consumption increases by ~1 mA. I want to reduce the current...
Hi Sir,
As we know the nPM2100 support AA/AAA batteries, LiMnO2 coin cells (e.g., CR2032), Alkaline coin cells (e.g., LR44) .
But could nPM2100 support CR123A 1S2P?
