Modules

1. Communication & IoT Modules

These are essential for your projects involving wireless control or data logging.

• Wireless: WiFi, Bluetooth (classic and BLE), and Zigbee modules.

• Long-Range: LoRa (Long Range) modules for extended distance communication.

• Cellular/GPS: GSM/GPRS modules for cellular connectivity and GPS modules for location tracking.

• Protocols: Logic level converters, multiplexers, and shift registers to help different components communicate.

2. Power & Management Modules

Since you work with robots and battery-powered systems, these are critical for your power distribution:

• Voltage Regulators: Buck (step-down), Boost (step-up), and Buck-Boost converters.

• Charging: Battery charger modules (for Li-ion, LiPo, etc.) and solar charger/controller modules.

• BMS (Battery Management Systems): Smart and hardware-based BMS units from brands like DALY and JBD to manage multi-cell battery packs.

3. Sensor Modules

Robu stocks a massive variety of sensors under their "SmartElex" brand and other labels:

• Environmental: Temperature, humidity, pressure.

• Movement & Proximity: PIR motion, IR sensors, ultrasonic distance, and line-tracking sensors.

• Specialized: Current sensors (for monitoring your robot's motor draw), RFID, radar, and imaging sensors.

4. Display & Interface Modules

For human-machine interaction in your gadgets:

• Displays: OLED, TFT, HMI (Human-Machine Interface), Character LCDs, e-Ink/Paper displays, and LED dot matrix modules.

• Input: Keypads, electronic switches, and potentiometer modules for manual control.

5. Control & Drive Modules

These are core to your robotics and automation work:

• Motor Drivers: Drivers for brushed/brushless DC motors and stepper motors (including Pololu, Cytron, and Dimension Engineering brands).

• Relay Modules: Used for switching high-voltage or high-current loads via your microcontroller.

• MOSFET Drivers: For precise switching and speed control.

6. Audio & Signal Modules

• Audio: Audio amplifier modules and buzzer/speaker drivers.

• Signal: Signal generators and various breakout boards for testing and prototyping.
