The Bus Servo Driver HAT (A) with the ESP32-WROOM-32 microcontroller enables simultaneous control of up to 253 ST and RSBL servos, supporting both wired and wireless communication in robotic applications. Designed for integration with Raspberry Pi, it features 5 V power supply from a converter and full support for UART and USB-C transmission. JSON command handling and automatic WiFi network startup allow for remote control and easy integration with various development environments. Ideal for robotic arm projects, walking robots, and other constructions requiring multiple servos with closed-loop control.
Description
An expansion module in HAT format for Raspberry Pi that enables simultaneous control of up to 253 servos with an ST or RSBL serial bus interface. The integrated ESP32-WROOM-32 microcontroller supports both wired and wireless communication, allowing the device to function as the main controller in robotic projects. Power supply ranging from 9–25 V is delivered via an XT60 connector or a 5.5 × 2.5 mm DC socket and simultaneously powers the connected servos. The board includes a 5 V buck converter to power the Raspberry Pi, as well as UART and USB-C ports for communication and servo control.
The module supports sending and receiving commands in JSON format, which facilitates integration with various control systems and software development. Upon powering on, it automatically starts a Wi-Fi access point, allowing wireless control via a web application. With full support for the Raspberry Pi platform and communication via WiFi, Bluetooth, and ESP-NOW, the HAT can be used for advanced control and debugging of servos in projects such as walking robots, robotic arms, or multi-legged constructions.
