Great value but documentation could be better

The hardware quality is excellent for the price. It took me a while to figure out the serial command structure because the manual was a bit sparse, but once I got it working, it's been rock solid.

Reliable and compact

Fits perfectly into tight chassis designs. The power distribution is stable even when all 24 channels are under load. No overheating issues observed during extended testing sessions.

Smooth motion control

I am using this for a robotic arm project. The movement is incredibly smooth, and the ability to add an MP3 module for sound effects is a fun bonus feature that my kids love.

Best controller in this price range

I've tried several other 24-channel boards, and this one offers the best balance of features and stability. The support for custom scripts via the serial interface is a game changer for advanced users.

Good board, tricky initial setup

The board works well now, but getting the firmware updated initially was frustrating. Make sure you have the correct USB-to-TTL adapter before starting. Once configured, it performs as advertised.

Perfect for my hexapod robot

This board handles all 18 servos for my spider robot without breaking a sweat. The Bluetooth module pairing was instant, and the joystick control is very responsive. Highly recommended for complex DIY projects.

5 FAQ

Q: Can I daisy-chain multiple controllers for more than 24 channels?

A: Yes, you can connect multiple boards via the UART interface to expand the channel count, though each board will need to be addressed individually in your code.

Q: Can I power high-torque digital servos directly from this board?

A: Yes, provided your external power supply can handle the total current draw. The board supports up to 1A per channel, but please ensure your main power source is robust enough for high-torque applications.

Q: Is there software available for Windows to configure the servo angles?

A: Yes, we provide a free PC tuning software compatible with Windows 7/10/11 that allows you to visualize and adjust servo positions, speeds, and groups via USB.

Q: What is the maximum baud rate supported for serial communication?

A: The controller supports baud rates from 9600 up to 115200 bps. We recommend 57600 or 115200 for the smoothest real-time control performance.

Q: Does this board come with the Bluetooth module included?

A: No, the Bluetooth module is sold separately. The board has a dedicated port to easily connect compatible HC-05 or HC-06 modules.
