To connect the NRF24L01 module to a 3.3V power supply, follow these steps:
< br >
1. Locate your 3.3V power supply device or module. You can use the 3.3V power supply pin on your development board or use a dedicated 3.3V power supply module.
< br >
2. Make sure your power supply meets the requirements of the NRF24L01 module. The NRF24L01 module requires 3.3V power supply, and can not use 5V power supply or directly connect to 5V pin on Arduino development board as power supply.
< br >
3. Connect the positive terminal () of your power supply to the VCC pin of the NRF24L01 module.
< br >
4. Connect the negative terminal (-) of your power supply to the GND pin of the NRF24L01 module.
< br >
After ensuring that the power connection is correct, your NRF24L01 module will be able to receive the 3.3V power supply and start working. Please be sure to pay attention to the stability of the power supply and the current demand of the entire circuit to avoid excessive current or voltage fluctuation resulting in unstable or damaged NRF24L01 module.
To connect the nRF24L01 wireless transceiver module with 3.3V power supply, connect the positive terminal of the 3.3V power supply to the VCC pin of the module, and connect the negative terminal of the power supply to the GND pin. In addition, in order to ensure the stability of the power supply, it is also necessary to connect a suitable capacitor (such as a 10uF capacitor) next to the VCC pin and connect its negative terminal to the GND pin to reduce power noise.
At the same time, it is also necessary to pay attention to the correct connection of the communication pins (such as MISO, MOSI, SCK, CE, CSN, etc.) between nRF24L01 and the main control chip (such as Arduino). In this way, the nRF24L01 module can work properly and communicate wirelessly with other devices.
1. The nrf24l01 power supply 3.3v can be connected directly to the 3.3v power supply pin. This is because the nrf24l01 module requires a 3.3v power supply to work properly.
A direct connection to the 3.3v power supply pin ensures a stable power supply to the module. It is worth noting that if your power supply is supplied through another circuit or module, you need to ensure that its output voltage is 3.3v and that it can provide enough current to meet the needs of the nrf24l01. At the same time, you can also use a voltage regulator chip or power module to provide a stable 3.3v power supply.
Find the 3.3v output point of the power supply and connect it to the place that needs this voltage.
