RPLIDAR S1 development kit includes the matched tools used for evaluating
RPLIDAR’s performance and initial development. After connecting the RPLIDAR S1
with PC via USB cable and connecting the power adapter to the USB cable, users
can observe the cloud map of the environment scanning point collected by the
RPLIDAR in RoboStudio and start development based on the SDK.

RPLIDAR S1
Figure 1-2 The RPLIDAR
The RPLIDAR S1 development kit contains standard RPLIDAR S1 unit (S1M1). The
RPLIDAR is embedded with logic IO drivable motor controller which can be used
to configure the scan frequency by tuning motor speed. Developers can also
choose to turn off the motor for power saving purpose.
RPLIDAR usage and interface definition will be introduced in the coming sections.
USB Adapter
The USB adapter comes with a dial switch. It can be used to switch the Baud rate
from 115200 to 256000 or vice versa, which is compatible with RPLIDAR S1 and
former RPLIDAR series. Please note that the Baud rate should be set as 256000 if
the USB adapter is connected with RPLIDAR S1..

Connection
RPLIDAR S1 can be easily connected to PC according to the following steps.
1) Connect RPLIDAR S1 with the USB adapter.
Figure 2-1 Connect RPLIDAR S1 and USB Adapter
2) Connect the USB adapter to your PC via the Micro-USB cable. If the PC is
on, after connecting the USB cable to your PC and connecting the power
adapter to the USB cable, the indicator light of the USB will light up but the
RPLIDAR will not start scanning.
Figure 2-2 Connect the USB Adapter to PC via Micro-USB Cable
Install Driver for the USB Adapter
The USB adapter converts UART to USB by using CP2102 chip. You need to install
the device driver for the chip. The driver can be found in the provided SDK
package or downloaded from Silicon Labs’ official website:
http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
Here’s the installation steps in Windows: after connecting the RPLIDAR with PC,
please find the driver file “CP210x VCP Windows” and choose correct operating
system version accordingly: x86 for 32-bit OS and x64 for 64-bit OS.
