Atlas Autoware car v2: drive board (ESC, BMS, USB-C charging), Jetson carrier, printed kit
The second Atlas Autoware car: a Traxxas Slash 4x4 with a Holmes Hobbies Puller Pro 540 motor, a SICK TiM561 lidar and a LUCID Triton camera, rebuilt so that almost nothing is wired by hand. Two custom circuit boards stack on a carbon-fibre-printed deck:
- Drive board (ATLAS-DRV-1). The ESC (VESC firmware, same UART commands as car 1), a battery protector for a built-in 4S3P 18650 pack, USB-C charging, the servo supply, the lidar's power switch and a USB hub. - Brain board (ATLAS-BRN-1). A Jetson Orin Nano carrier forked from Antmicro's open-source design, with PoE for the camera and a…

Atlas drive: common questions
What microcontroller does the Atlas drive use?
The Atlas drive is built around the STM32F405RGT6, from the STM32 family.
How big is the Atlas drive PCB?
The Atlas drive measures 140 × 90 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Atlas drive?
377 components, from 130 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Atlas drive design files?
From the AtlasAutoware/carv2 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Atlas drive design in my own project?
The repository has no license, so all rights stay with AtlasAutoware. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Atlas drive without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
