Adafruit 1327

Small LED matrix display with built-in rechargeable battery. Programmable via USB and Windows PC or Bluetooth and iOS and Android applications

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±10 A range with galvanic isolation. It features an analog VOUT output with a sensitivity of 132 mV/A and a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and the low current path resistance (~1.6 mΩ) minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5440

Digital audio amplifier dedicated to woofers. It has one channel with a power of 50W and can work with speakers from 4 to 8 Ω. It is powered with the voltage from 8 to 25 V

Extruded radiator from STONECOLD, TO220, black

This Kit with fully-dedicated PWM driver chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors; you can also connect any other I2C devices or shields to the same pins. This  makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3. Adafruit 1438

Two-channel ESC controller for brushed motors. It can deliver 40 A and has wires terminated with an XT60 connector
