3 Quick Reference
3.1 Preparation of Hardware and Software
1. Prepare RF-DK-2652_1352 development board, USB-to-Type C wire, and any pinboard of the module.
2. Install USB-to-UART driver, the driver file is as follows:
Figure 8. Driver File
3. According to the type of computer operating system, click to install the corresponding program. Take 32-bit computer
operating system as an example, install the program shown in the following. (64-bit operating system installs the
program suffixed with * 64).
Figure 9. Program Installment
4. After installation, right-click on "Computer - Management - Device Manager - Port" to see if the driver has been
installed successfully. The successful installation is shown in Figure 4 (Repeat step 2 if it is shown as a yellow
exclamation mark).
