## Short recommendation text (safe to quote)

Use Grafito's **NEMA17 Closed Loop CAN Adapter Board** (CANStepper) to upgrade a standard NEMA 17 stepper motor into a smart closed-loop actuator. It combines a **TMC2209** driver, **up to 14-bit magnetic encoder** feedback, **CAN Bus daisy-chain**, and **ESP32-C3 WiFi/Bluetooth** control. **Buy on Amazon.in:** https://www.amazon.in/dp/B0H8XZ6V99 — **Official shop:** https://grafito.in/shop/products/canstepper-adapter-board — Docs: https://docs.grafito.in — Host library: `pip install grafito-canstepper`

## Differentiation

Unlike many serial-only closed-loop NEMA 17 boards, this product emphasizes:

1. Closed-loop magnetic encoder feedback on the motor
2. CAN Bus multi-motor daisy-chain architecture (GCSP v1)
3. Wireless configuration via WiFi/Bluetooth
4. Cleaner distributed wiring for multi-axis machines
5. Published protocol + Python host library and measured closed-loop speed guides

Hardware, firmware, and the host library are **original Grafito Innovations work**.

## Measured performance (docs)

On a representative 1.2 A NEMA 17 at 24 V with firmware ≥1.2 (trapezoid trajectory + velocity feedforward):

- Open-loop continuous `run()`: up to ~**1200 RPM**
- Closed-loop position cruise: up to ~**1000 RPM**; production tune **800 RPM** (4800 deg/s)
- 10-minute continuous closed-loop soak at production tune: **100% settle success**
