This library allows developers to directly control the onboard sensors as well as hundreds of connected sensors and actuators using the popular Python programming language. With this level of control, developers can create interactive and responsive projects that leverage the full potential of the hardware capabilities.
How to program a Unihiker single-board computer?
To wirelessly program Unihiker, the first step is to connect it to a Wi-Fi network. This can be done by either connecting Unihiker to a router or by utilizing a mobile phone hotspot. It is important to note that when connecting to a Wi-Fi network, Unihiker operates on the 2.4GHz frequency, so it is crucial to ensure that the Wi-Fi network being used is compatible with this frequency.
Once Unihiker is connected to the Wi-Fi network, users can connect their programming devices, such as a computer, tablet, or smartphone, to the same Wi-Fi hotspot. This allows the programming devices to establish a connection with Unihiker over the network.
To initiate the programming process, users need to enter the IP address of Unihiker in the programming environment they are using. This IP address serves as the identifier to establish communication between the programming device and Unihiker. By entering the IP address, users can establish a connection and start programming Unihiker wirelessly.
Cost and availability
The Unihiker single-board computer is available for purchase on the DFRobot website for $68.00 USD. With its affordable price point and powerful capabilities, users can explore the capabilities of Unihiker.
