Unit 8Servos2-Chain - 8-channel servo controller with 5 V/3 A power supply - Chain protocol - STM32G031 - M5Stack U223
M5Stack Unit 8Servos2-Chain 8-servo controller with STM32G031: 8 channels with 5 V power up to 3 A from a single 9-24 V supply.
- You control it over UART with the Chain protocol
- Servos, power supply and controller sold separately, 20 cm Grove cable included

Eight servos from a single module
M5Stack Unit 8Servos2-Chain controls 8 channels with an STM32G031 microcontroller. You can set each channel as a servo output, an input or a digital output, an analog input, RGB LED control or PWM.
You power the module from a 5.5 x 2.1 mm DC jack with 9 to 24 V, and the converter supplies the servos with 5 V and up to 3 A in total. It communicates with the controller over UART using the Chain protocol, so you can connect further modules one after another. The board also measures the current of all servos and the supply voltages.

Botland is an official distributor of the M5Stack module family in Poland. We have extended this system of stackable functional devices with accessories from our range and numerous blog guides. All M5Stack products presented here are original.
Is it right for you?
A good choice if:
- You are building a robot with several servos and want a single power supply
- You want to measure the total current drawn by the servos
- You want to mix servos, buttons and RGB LEDs on a single module
Consider another option if:
- You need many modules on one I2C bus with address selection: choose the Unit 8Servos2-I2C version
- An older servo driver for an M5Stack controller is enough for you: 8-channel servo driver - M5Stack U165
Fun fact
Two LEDs keep watch over the power
The red LED lights up when the DC jack receives more than 8.5 V, and the green one warns when the voltage on the HY2.0-4P port drops below 4.5 V.
Frequently asked questions
What power supply does Unit 8Servos2-Chain need?
A 9 to 24 V DC power supply with a 5.5 x 2.1 mm plug, positive in the center. The servos receive 5 V from the converter.
How many servos can I connect to one module?
Eight, but the total current of all channels is up to 3 A at 5 V.
How does the Chain version differ from the I2C version?
Chain links modules in a chain over UART. The I2C version has 16 addresses selectable with a knob.
