Stm32f407 Robot Control Board ROS Smart Car Main Control 4WD Radar Obstacle Avoidance for NanoB01 Smart Car Main Control (2WD) detailed explanation. The B01 motherboard is designed based on intelligent vehicle and ROS scenarios, and can control chassis such as differential and track. It provides corresponding codes and tutorials. The motherboard can communicate with the outside world via the serial port and provides a 5V5A interface for external power to boards like Raspberry Pi or Nano. The code and schematic are all open source. B02 ROS Bot Main Controller (4WD) Motherboard Detailed Explanation. B02 is the main control board for ROS training robots. Based on the design of the ROS application scenario, it can control any chassis, including differential, Mecanum wheels, tracks, and so on. All provide corresponding codes and tutorials. The motherboard can communicate with the outside world through the serial port or CAN, and provides a 5V5A interface for external power to Raspberry Pi or Nano and other boards. The code and schematic are all open source. Supports direct connection to LiDAR. Lidar data can be read and used directly, achieving radar obstacle avoidance and tracking without an ARM board. Supports linear CCD line inspection and electromagnetic line inspection, with a reserved line inspection interface. Supports two line inspection methods: linear CCD and electromagnetic line inspection, and provides a principle manual for line inspection sensors: 2WD Material: ABS Color: As shown Package Contents: 1 x male cable 1 x circuit board 1 x display Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture to be slightly different from the real thing. The allowable measurement error is +/- 1-3 cm.
