What is it?

DeepSleep dev.board is a board with the minimum required circuitry for stable operation and startup. It is designed for testing and developing battery-powered devices.

Why did you make it?

In the world of Internet of Things (IoT) and embedded systems, one of the most pressing challenges is achieving long battery life while using powerful microcontrollers. Many off-the-shelf development boards, while convenient for rapid prototyping, often include components such as USB-UART converters, indicator LEDs, or complex voltage regulators that consume significant quiescent current. This makes them unsuitable for truly low-power battery-powered applications.

Meet the DeepSleep dev.board — a board designed as a direct solution to this problem. The core idea was to create a development board with the minimal necessary set of components for normal and stable controller operation. This board is specifically designed for debugging ultra-low power consumption devices powered by batteries. Its specialized approach makes it an indispensable tool for developers where every microampere of consumed current directly affects device lifespan.

What makes it special?

The board consumes a minimal amount of standby current. All voltage regulators, LED indicators, and firmware upload chips have been removed, allowing for maximum power savings—down to 5 µA in hibernate mode.
