== Technical overview ==
* Supports four 18650 batteries (not included); two in parallel and two in series for higher current output.
* Onboard HY2120 + AOD514 lithium battery protection circuit with overcharge, over-discharge, overcurrent and short-circuit protection.
* Integrated FP5139 buck-boost regulator provides stable 5 V to the Jetson Nano.
* 0.91-inch OLED display (128×32) shows IP address, memory and power status.
* AINA219 acquisition chip enables real-time monitoring of battery voltage and charging current.
* Software image based on JetPack 4.5; requires an SD card of at least 64 GB.
* Access via Jupyter Lab at http://<jetson_ip>:8888 using default password "jetson".
* Controlled via car.steering (range [-1,1]) and car.throttle (range [-1,1]); gain and offset values calibrate direction and top speed.

'''Commands and examples – verify before use:'''

== Notes and version constraints ==
* The Jetson Nano Dev Kit is not included in the standard variant; only variant B (WSAL18433) includes it.
* Batteries are not shipped due to shipping policy – source them locally.
* The software guide is largely based on the NVIDIA JetRacer wiki; Waveshare-specific drivers must be installed or errors will occur.
* If motor issues arise: use Waveshare code instead of NVIDIA code; if NVIDIA code was updated, delete the jetracer folder and re-download Waveshare's version.
* Orin Nano boards are not compatible with the JetRacer Pro chassis according to the source (different power method, project incompatibility).
* System voltage drops to about 9 V when batteries are weak; recharging recommended below 10 V.
* Camera start after program exit may cause errors; restarting nvargus-daemon is required.
* Teleoperation: connect the gamepad receiver to the PC, not the Jetson Nano; adjust the INDEX value in the notebook accordingly.
