USB2AX v3.2b - USB to Dynamixel Servo Interface Adapter
The USB2AX v3.2b is a compact, high-performance USB-to-TTL serial adapter purpose-built for communicating with Dynamixel AX and MX series smart servos. Designed around an ATmega32U2 microcontroller, it provides a direct USB half-duplex connection to Dynamixel's TTL bus - eliminating the need for bulky USB-to-serial converters and external direction-switching circuits. Ideal for robotics projects, humanoid platforms, and servo-driven mechanisms. Available now at The Tech Depot, Bengaluru, India.

Key Features
- Native Dynamixel Half-Duplex: Hardware-managed direction switching eliminates timing issues and external buffer ICs - just plug in and communicate with your servos instantly.
- Built-in SYNC_READ: Firmware-level support for the SYNC_READ instruction dramatically speeds up reading data from multiple servos simultaneously - critical for real-time robotic control loops.
- Ultra-Compact Design: At just 47 x 20 mm, the USB2AX fits easily inside tight robot chassis, arm assemblies, and embedded enclosures where space is at a premium.
- Up to 1 Mbps Communication: Supports the full range of Dynamixel baud rates for high-speed servo command and feedback cycles.
- True Plug-and-Play: Recognized as a standard CDC virtual COM port on Windows, Linux, and macOS - no proprietary drivers required on most systems.
- Open-Source Firmware: Fully open-source firmware with DFU bootloader allows custom modifications, bug fixes, and community-driven enhancements.
- Low Latency: The ATmega32U2's direct USB implementation provides significantly lower latency compared to FTDI or CH340-based USB-to-serial adapters with external direction control.
- Broad Software Ecosystem: Works seamlessly with Dynamixel SDK (C, C++, Python, Java, MATLAB), ROS dynamixel packages, RoboPlus/Dynamixel Wizard, and any serial terminal application.
- Daisy-Chain Ready: Connect dozens of Dynamixel servos on a single TTL bus through the 3-pin Dynamixel connector - each servo addressed by unique ID.
Why Choose the USB2AX v3.2b?
- 100% Authentic: Sourced directly from authorized distributors - guaranteed genuine USB2AX hardware with latest v3.2b revision.
