About Us

MicroPowerCore is a small independent hardware brand focused on power supply and ultra-low-power design for battery-operated electronics.

We design and sell two boards: the MicroPowerCore v1.2 — a single-cell Li-Ion/Li-Po charger combined with a buck-boost converter on one 33 × 12 mm board — and the DeepSleep dev board, a minimal ESP32 development board built for microamp-level sleep-current experiments. Alongside the hardware we publish documentation, schematics and guides on low-power ESP32 design, all tested on real hardware.

We do not sell directly from this website. Our boards are available on Tindie and Lectronz, with shipping from Germany.

If you have any questions, suggestions, or would like to collaborate with us, please feel free to get in touch at hello@micropowercore.com.

Support & Warranty

For technical questions about wiring, specifications or firmware, email us at hello@micropowercore.com — please include your board version and a short description of your setup. We usually reply within a few business days.

Orders are processed by the marketplace you bought from. If a board arrives damaged or defective, contact us by email or through your Tindie/Lectronz order page and we will arrange a replacement or refund under the marketplace's buyer protection rules and applicable consumer law.

Thank you for visiting MicroPowerCore!
