# ARK 12S CAN ESC

NDAA compliant, made in the USA, single channel electronic speed controller with CAN FD, designed for 12S brushless propulsion.

The ARK 12S CAN ESC is a single motor, three phase speed controller for 4S–12S packs, built around an STM32G431 MCU and a [TI DRV8350H](https://www.ti.com/product/DRV8350) gate driver. It reports telemetry over CAN FD and accepts a conventional single wire signal input, so it can be used either as a CAN node or as a drop in replacement for a PWM/DShot ESC. It runs ARK32 with a DroneCAN interface and works with PX4 and ArduPilot. Power and phase connections are made through threaded SMT standoffs rather than wires, so the ESC bolts directly to a bus bar or motor mount. USA built and NDAA compliant.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.arkelectron.com/products/electronic-speed-controller/ark-12s-can-esc.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
