Adding wireless capability is a game-changer for Arduino projects. SunFounder offers a comprehensive range of communication modules to suit any range or power requirement:
○ Bluetooth (HC-05/HC-06): The standard for short-range communication. Perfect for controlling robots or reading sensors via a smartphone app.
○ Wi-Fi (ESP8266/ESP-01): The gateway to the Internet of Things (IoT). Connect your Arduino to your home network to log data to the cloud or control devices remotely.
○RF Transceivers (NRF24L01): Ideal for reliable, low-power communication between two Arduino boards over medium distances (up to 100m or more with an antenna).
Wireless communication can be tricky due to interference and power issues. SunFounder Arduino communication modules are built with high-quality components to ensure stable signal transmission. We provide clear pinout diagrams and example code (libraries) for every module, helping you establish a connection in minutes rather than hours. Whether you are building a smart home system or a remote control car, our modules deliver the connectivity you can trust.
○ What is the range of the NRF24L01 module?
The standard NRF24L01 module has a range of about 100 meters in open space. We also offer the NRF24L01+PA+LNA version with an external antenna, which can extend the range up to 1000 meters.
○ Can I use the HC-05 Bluetooth module with an iPhone?
The classic HC-05 supports Bluetooth 2.0 (Classic), which works great with Android but is generally not supported by iOS. For iPhone connectivity, we recommend using a Bluetooth Low Energy (BLE) module like the HM-10 or AT-09.
○ Do these modules require a separate power supply?
Some high-power modules like the ESP8266 or NRF24L01 (with PA) can draw peak currents that exceed the Arduino's 3.3V pin limit. We recommend using a dedicated 3.3V voltage regulator or a breakout adapter board (which we sell) to ensure stability.
