NRF2USB is a simple development tool designed specifically for wireless applications that utilize the low-cost nRF24L01+ 2.4GHz transceiver module. The integrated CH55x microcontroller provides a USB interface for communication with the module. The versatility of this tool makes it an ideal choice for a wide range of wireless applications.

Depending on the firmware, it can be used, for example, to transfer serial data wirelessly between two PCs (USB CDC - Communications Device Class) or as a receiver for wireless keyboards, mice or joysticks (USB HID - Human Interface Device). It is also possible to receive sensor data or control remote actuators. This makes it ideal for IoT (Internet of Things) applications where data collected from sensors needs to be transmitted wirelessly to a central device for analysis.
