M5Stack CM4Stack Development Kit


Description

CM4STACK is an all-in-one micro host based on the Raspberry Pi CM4 Core Board, featuring the CM4104032 model with built-in Wi-Fi, 4GB of RAM, and 32GB eMMC. This host includes a wealth of peripherals: a 2.0-inch IPS-LCD touchscreen with a resolution of 320x240, 2 USB3.2-A ports (PCIe + ASM3042), a USB-C (2.0) port with OTG and power delivery support, a high-resolution multimedia signal interface, a Gigabit Ethernet RJ45 port, a DC-JACK power input (12V@3A), 2 HY2.0-4P expansion ports for I2C and UART, a 2W speaker powered by an AW88298 16-Bit I2S amplifier, a secure encryption chip (ATECC608B), and an RTC chip (BM8563). The device also includes an active cooling fan and an aluminum heat dissipation frame. It supports DIN rail, wall mounting, and screw fixing, making it suitable for industrial automation, smart home, IoT, and other applications.
