Hardware description
The PPC-CM4-121 is designed for industrial usage, ready to deploy applications based on the Raspberry Pi Compute Module 4 (Quad Cortex®-A72 processor at 1.5GHz clock).
It supports panel, front mount, and VESA mount for different integration applications.
The 12.1” screen with a ten-point capacitive touch and 1024×768 pixel resolution at 400 NIT brightness make this interaction stable with excellent image clarity. It is durable and resistant to environmental contaminants like dust and water.
Wireless connectivity is a must nowadays, and the PPC-CM4-121 shines on this front. Besides the integrated Ethernet connector supporting up to 1000Mbps and WiFi + BLE wireless module, optional 4G/LTE and ZigBee modules are available.
Wired connectivity includes also two USB 3.0, a USB-C connector OTG port, a Giga-Ethernet, and an extension connector (featuring RS232, RS485, CAN, GPIO). The audio section is also complete with a front panel microphone, a 3.5mm audio connector, two 2W internal stereo speakers, and one internal Buzzer.
The PPC-CM4-121 supports a wide range of input voltages from 12V to 36V DC with a typical power consumption of 13.2W, featuring a wide range of protection features, allowing it to meet stringent industrial safety regulations.
