ESP32 Starter Kit with Breakout Board and 9V Battery

Overview

Power and wiring are usually the two things that slow a wireless project down. This kit removes both: it pairs the industry-standard 30-pin ESP32 development board (ESP-WROOM-32) with a matching breakout board and a 9 V battery holder with an alkaline battery already included, so you can build a genuinely untethered IoT node straight out of the box.

The battery holder terminates in a DC 5.5 × 2.1 mm plug that drops straight into the breakout board — take the project outside, mount it on a robot, or leave it somewhere a wall adapter will never reach. The breakout board also expands every GPIO pin from one to two, which makes wiring sensors, relays and displays far less fiddly, and offers USB Type-C and micro-USB inputs for benchtop work.

Whether you are a hardware engineer prototyping a remote sensor or a student building a first smart-home gadget, everything here works with the Arduino IDE and MicroPython without any soldering.

Key Features
