 To program the firmware onto the MCU, we need an [ST-LINK V2](https://www.st.com/en/development-tools/st-link-v2.html) programmer. Please refer to the programming process outlined in the[STM32CubeProgrammer user manual](https://www.st.com/resource/en/user_manual/um2237-stm32cubeprogrammer-software-description-stmicroelectronics.pdf).

+After preparing all the required sensors, actuators, and the assembled PCB, please connect the components according to the wiring diagram below. 
+The diagram includes the PIN definitions for each sensor's XH2.54 interface, arranged in the same order as they appear on the actual PCB. 
+The entire PCB (and the sensors) can be powered through a DC 24V input.

 # :minidisc: II. Prepare Code and Datasets
 
 We also provide multiple pre-collected datasets to test 𝛼LiDAR's performance if the hardware is not available. The dataset can be downloaded at [Mega Drive](https://mega.nz/folder/fEpwARjD#AVRIQ-gzrFtTJn6fuwmXng) or [Baidu Pan (Code: u0tr)](https://pan.baidu.com/s/1nzBAgfkNCF8X1rAMBUw8Rg).
