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.

Our boards are available directly on this website (payment by Stripe) and on Tindie and Lectronz, with shipping from Germany — see delivery & returns.

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.

Marketplace 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. Direct orders: see delivery & returns and the right of withdrawal.
