Hack the RPLiDAR-A1 Laser Scanner

Hacking the RPLiDAR A1 is very similar with the Hacking of Neato XV-11 Laser Scanner:

They all use UART-TTL as the data transmission protocal. So we need to find out the TX and RX wire for the scanner to communicate with the UART-USB converter.

Below is the picture of the RP-LiDAR A1:

It consists of a driving motor, a laser scanner, a circuit board and a converting board.

In order to transfer the data with a revolving scanner, I choose to use the wireless solution: bluetooth, XBee, photoelectricity etc.

Finally, I added a bluetooth transceiver on the top of the scanner:
