M5Stack CM4Stack Development Kit (CM4104032)
The CM4Stack is an integrated micro host based on the Raspberry Pi CM4 core board, using the CM4104032 module with built-in WiFi, 4GB of memory, and 32GB eMMC. The host includes rich peripheral devices: a 2.0″ IPS-LCD screen with capacitive touch, a resolution of 320×240, 2 USB 3.2-A ports (pcie+ASM3042), a USB-C (2.0) interface that supports OTG and host power supply.
Also included is 1x HDMI interface, 1x Gigabit Ethernet interface (RJ45), 1x DC-JACK DC power input interface (12V@3A), 2x HY2.0-4-Pin expansion ports, which are I2C and UART interfaces respectively, built-in 2W speakers, equipped with AW88298 16-Bits I2S amplifier, 1x ATECC608B security encryption chip, 1 RTC chip BM8563, built-in active cooling fan and an aluminium alloy heat sink frame. This product supports DIN rail, wall hanging, and screw fixing methods in structure, and is suitable for industrial automation, smart homes, and IoT fields.
