UHF_Lite_Pico_Expansion_Software

The frequency range of the UHF (Ultra High Frequency) Lite Expansion, a radio frequency device, is 300 MHz to 3 GHz. Wireless communication systems, such as radio-frequency identification (RFID) systems, Wi-Fi networks, and other short-range wireless communication applications, frequently employ UHF modules. UHF modules are created to send and receive signals over brief distances, usually up to a few hundred meters, and they have benefits like fast data transmission rates, low power consumption, and inexpensive price. Moreover, Anteena is on board.

Hardware Overview

Steps To Setup The UHF Lite UHF Expansion

Make sure to connect the jumper wire as per the below image, while UHF Expansion uses with PICO

1. Download Thonny IDE

https://thonny.org/

2. Install MicroPython in Raspberry Pi PICO first, you need to press the boot button and then connect the USB, Do,t release the button until you connect the USB to the laptop. then you see a new device named "RPI-RP2" drag this file "firmware.uf2" to this device as shown in figure
