Module with RTC and MicroSD socket for D1 Mini

Single-channel DC motor driver that can control the movement of the drive with a supply voltage of up to 36 V and a current consumption of up to 15 A. Controlled by a PWM signal. DFRobot DRI0042

Module with monostable relay. It allows you to control high-power elements with a microcontroller. Adafruit 3191

This Bluetooth Audio receiver module includes a USB port and TF card slot. With a pre-amp output, you can drive headphones or a 3W speaker directly. You can also add an active power amplifier and connect a loudspeaker. The module supports MP3, WMA, WAV and lossless FLAC audio formats. DFRobot TEL0108

Ultra small Dual DC motor driver for some room limited projects. UVLO (Under Voltage Latch-Out) features a safe guard for your system. DRI0041

The motor driver card can drive 24 servo motors at most. It can be used to drive a multiple-joint robot machine, such as Hexapod Robot, Biped Robot, and Arm Robot. P0288

BOB-13263

This powerful step-up/step-down regulator efficiently produces an adjustable 4 V to 12 V output from input voltages between 3 V and 30 V while allowing a typical output current of up to 2 A when the input voltage is close to the output voltage and offering typical efficiencies of 80% to 90%.

The power module together with the engine controller has been specially created for the Romi Chassis chassis. With its help, we will supply all components of our construction and we will be able to control the engines responsible for the movement of the chassis. Pololu 3543

Real time clock (RTC) module PCF8523. It communicates via the I2C interface. Adafruit 3295

Step-Down DC-DC converter module based on the D24V150F9 chip. Input voltage 11 ... 40V, output voltage 9V (max 15A). Pololu 2884

Step-Down DC-DC converter module based on the D24V150F7 chip. Input voltage 9..40V, output voltage 7.5V (max 15A). Pololu 2883

DFR0379

This synchronous switching step-down (or buck) regulator takes an input voltage of up to 40V and efficiently reduces it to 5V with an available output current of around 15A. Typical efficiencies of 80% to 95% along with its high current capabilities make this regulator well suited for powering large loads. Pololu 2881

Gravity: 360 Degree Hall Angle Sensor is a rotation angle sensor measuring a value in the range of 0-360 ° with an analogue output, powered by 5V. DFRobot SEN0221

Two-channel DC motor driver communicating via UART, SPI or I2C interface. It can control the movement of 3 to 11V motors with a maximum continuous current of 1.2A per channel. SparkFun ROB-13911

This synchronous switching step-down (or buck) regulator takes an input voltage of up to 40 V and efficiently reduces it to 3.3 V with an available output current of around 15 A. Pololu 2880
