The Raspberry Pi RMC20452T is a Wi-Fi 4 and Bluetooth 5.2 module designed for use with Raspberry Pi microcontrollers like the RP2040. It offers low power consumption and simple integration thanks to its gSPI interface and full radio certification. Ideal for IoT projects, home automation, and wireless communication systems

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 30 Voperating range and are efficient enough to deliver a continuous 18 A without a heat sink. The drivers offer basic current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation. 

A set of three heat sinks for Raspberry minicomputers: Pi 4 model B, Pi 3 model B+, Pi 3 model A+, Pi 3 model B, Pi 3 model B, Pi 2 model B and Pi 1 model B . The heat sinks have adhesive tape.
