Power Modules for Arduino, ESP32 & Electronics Projects

Power supply selection is one of the most important parts of any electronics project. AuscomTech stocks common power modules used with Arduino compatible boards, ESP32, ESP8266, Raspberry Pi compatible boards, STM32 projects, sensor circuits, relay modules, displays, motors and other low-voltage electronics.

Our range includes DC-DC converters for voltage conversion, voltage regulators for stable supply rails, battery charging boards for rechargeable battery projects and monitoring modules for checking battery condition. Always check input voltage, output voltage, current rating, polarity, heat dissipation, wiring requirements and battery chemistry before use.

Battery Charging, BMS, Monitoring & Protection

Battery-powered electronics often need more than just a holder or connector. Charging modules, battery monitoring boards, BMS boards and protection modules help manage power safely and reliably when used correctly. BMS and power protection modules are used for protection and management, while battery monitoring modules are used to display or measure battery status.

For lithium battery projects, always select charging and protection modules that match the battery type, cell count, voltage and current requirements. Incorrect battery charging or wiring can create safety risks, so check the product specifications carefully before connecting batteries.

Frequently Asked Questions

Do you sell power modules for Arduino and ESP32 projects?

Yes. AuscomTech stocks a growing range of power modules suitable for Arduino compatible boards, ESP32, ESP8266, Raspberry Pi compatible boards and general electronics projects.

What is the difference between a DC-DC converter and a voltage regulator?

A DC-DC converter is usually used to step voltage up or down, such as buck and boost converter modules. A voltage regulator is typically used to provide a stable fixed or adjustable output voltage for a circuit.

Where should battery level indicators go?

Battery level indicators, voltage displays and capacity display boards are best listed under Battery Monitoring Modules. BMS boards and protection circuits should be listed under BMS & Power Protection Modules.

Do you sell 18650 battery modules?

Yes. AuscomTech stocks battery holders, battery connectors and 18650-style battery modules depending on current availability.

Can you help me choose the right power module?

Yes. If you are unsure which power module suits your project, contact AuscomTech with your input voltage, required output voltage, current requirement, battery type and details of the device you are powering.
