Basic

SKU:K001

Description

Basic is an entry-level product with high cost performance in the M5Stack development kit series, ideal for beginners in development. It comes with a wealth of case resources, equipped with an ESP32 IoT chip, integrated Wi-Fi, and built-in 16 MB SPI flash memory. With its dual-core low-power design, it performs excellently in various application scenarios. It features an industrial-grade casing, exquisite appearance, and stable performance, breaking the traditional development board's limitations of being used only for verification and learning. With the advantages of rapid prototyping and ultra-low threshold, it helps developers achieve product-level results quickly, accelerating the development and productization process. A powerful hardware expansion system composed of multiple stackable modules and expandable units can quickly build and verify IoT products.

Basic has a practical and ingenious structural design, consisting of two stackable parts that can be separated. The top integrates the circuit board, chip, and other key components, while the bottom is equipped with a lithium battery, M-BUS bus socket, and expansion pins. This layout not only facilitates operation but also provides convenience for subsequent functional expansion.

USB Driver

Driver Download

Click the link below to download the driver program matching your operating system. There are currently two driver chip versions, CP210X (for CP2104 version) / CP34X (for CH9102 version) driver program packages. After decompressing the package, select the installation package corresponding to your operating system's bit version for installation. (If you are unsure which USB chip your device uses, you can install both drivers. CH9102_VCP_SER_MacOS v1.7 may report an error during installation, but it has actually completed the installation, just ignore it.)
