Specifications

Rich Peripheral Interfaces
Suitable For Different Types Of Robots
ESP32 Main Controller
Rich Resources For Secondary Development

Built-In WiFi And Bluetooth, As Well As ESP-NOW Support, For Wireless Communication

Support Multiple Peripheral Connections
40PIN GPIO Extended Header

The inner side 40PIN header is for directly connecting to the Raspberry Pi or other host boards. And extend the outer side 40PIN header for connecting with other HATs via cables

Serial Bus Servo Control

Allows Controlling Up To 253 ST3215 Serial Bus Servos At The Same Time

Note: One channel UART can control up to 253 bus servos, but due to the high power of the servos, it is necessary to consider whether the power supply solution is enough when using too many servos.
Voltage And Current Monitoring

Onboard Voltage/Current Monitoring Chip To Obtain The Power Supply Status Of The Robot At Any Time

Onboard 9-Axis IMU

Onboard QMI8658C + AK09918, For Detecting Movement, Orientation, And Magnetic Support Obtaining The Heading Angle Of The Robot Anytime And Anywhere
