Hello,
I know the current limit of 15mA to share among all gpio pins.
If I source/sink current in very short bursts (100ns every 1ms) can I draw larger currents than 15...
Dear All,
We are working on a custom board with NRF51822.Everything works fine apart from the timer. What we are doing is that once the board is booted, it reads some values...
Situation:
We are building BLE device that have GATT service showing a analog sensor value.
AIN2 is connected to the sensor. AIN4 is connected to battery.
We would like...
