16-channel servo driver HAT (B) module for Raspberry Pi - Waveshare 17035

The core of a small robot, either as an auxiliary controller atop a Raspberry Pi base or as a complete control solution on its own. Its Atmel ATmega32U4 microcontroller comes preloaded with an Arduino-compatible bootloader. This version does not include any through-hole components or connectors, allowing for customized assembly or standalone use. Pololu 3118

DC motor driver that allows you to control the movement of two drives using the I2C interface. Board with connectors for assembly. Pololu 5049

This add-on board makes it easy to control two high-power DC motors with a Raspberry Pi. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 36 Voperating range and are efficient enough to deliver a continuous 14 A without a heat sink. The drivers offer basic current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation.

Adafruit 16-Channel PWM / Servo HAT for Raspberry Pi - Mini Kit (Adafruit 2327)

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.

This programmable module combines with a Raspberry Pi to serve as the control center of a small robot or electronics project. Its Atmel ATmega32U4 microcontroller comes preloaded with an Arduino-compatible bootloader, and the board includes dual motor drivers that can deliver 1.8 A per channel to two brushed DC motors.
