waveshare ESP32 Servo Driver Expansion Board, Built-in WiFi and Bluetooth 6~12V Voltage Input UART Serial Bus Control Allows Controlling up to 253 SC, ST Series Serial Bus Servos Simultaneously

Overview This product supports the programming of servos to change the ID and working mode of the servos (servo mode/motor mode) in theory, it can control 253 bus servos and read the current angle, load, voltage, mode, and other information of each servo, and can use the serial port to communicate with the upper computer, which is used to build the lower computer of the robot project, and the on-board OLED. The screen can be used to display key information and is suitable for robot projects that require feedback on the angle and load of the servos such as robotic arms, hexapod robots, humanoid robots, wheeled robots, etc. Features Allows controlling up to 253 SC, ST series serial bus servos at the same time (adequate power supply required) Wide range voltage input 6-12V (the input voltage and the servo voltage must be matched) Built-in WiFi and Bluetooth, as well as ESP-NOW support, for remote control and servo debugging Automatic download circuit for easy uploading programs Open source web application and various robot structures Compact size and space saving, suitable for integration into sorts of space-limited projects Specifications Supply voltage: DC 6-12V Power supply connector: 5.5 × 2.1mm DC Download interface : Type-C Controller: ESP32 Control interface: UART Dimensions : 30 × 65mm Mounting hole size : 2.75mm Mounting hole spacing: 23 × 58mm Online Tutorial/Online Document: n9.cl/5btb2 Package Content Servo Driver with ESP32 x1 Screws pack x1

• 【UART serial bus control】Allows controlling up to 253 SC, ST series serial bus servos at the same time. 【6 ~ 12V wide voltage input】the input voltage and the servo voltage must be matched.
• Allows controlling up to 253 SC, ST series serial bus servos at the same time (adequate power supply required).
• 【ESP32 controller, extensive resources, Easy secondary development】 Built-in WiFi and Bluetooth, as well as ESP-NOW support, for remote control and servo debugging.
• 【WiFi remote control】 Built-in WiFi and Bluetooth, as well as ESP-NOW support, for remote control and servo debugging
• 【Application examples】 Servos will provide various feedback like position, speed, torque lock, operating mode (servo mode, servo motor mode, etc.) for advanced projects requiring closed-loop automatic control. Ideal choice for building quadruped robots, hexapod walkers, robotic arms and other robotic projects requiring multiple servos.
