M5Stack Core2 ESP32 IoT Development Kit vs SparkFun ESP32 Thing Plus
Side-by-side comparison of features, pricing, ratings, and alternatives.
The M5Stack Core2 is an all‑in‑one development kit built around the ESP‑32 MCU, featuring a 2.0" capacitive touch display, built‑in speaker, microphone and a 6‑axis IMU. It includes a TF‑card slot, lithium‑polymer battery and USB‑C power, making it ready for portable projects out of the box. Supported by UIFlow, MicroPython, Arduino and ESP‑IDF, the Core2 lets makers and engineers quickly prototype AIoT applications such as wearables, smart sensors, and edge‑AI devices without additional shields or wiring.
The SparkFun ESP32 Thing Plus is a small, breadboard‑friendly development board that packs a dual‑core ESP32‑WROOM‑32U module, USB‑C power and programming, and a rich set of peripherals. It’s designed for rapid prototyping of IoT, wearables, and sensor projects while keeping the footprint low. With built‑in voltage regulators, a reset button, and a Qwiic‑compatible I2C header, the board offers both flexibility and ease of use for hobbyists and engineers alike. Its open‑hardware design encourages community contributions and custom extensions.
