Raspberry Pi is a popular computing platform which has become incredibly popular with technology enthusiasts, hobbyists, educators, as well as professionals.
Thanks to its compact size, affordable price and versatility, the Raspberry Pi has become a perfect tool for exploring the world of programming, creating various projects and developing a multitude of applications and systems. The TME catalogue has recently been expanded to include a wide range of new Raspberry Pi products, including Compute Module 4S (CM4S) models.
Compute Module boards are compact versions of Raspberry Pi single-board computers (in this case Generation 4, model B), stripped of standard connectors. Instead, they are fitted with a comprehensive port which offers extensive capabilities (including typical interfaces, such as USB and HDMI), thanks to which designers/developers can create a miniaturised device circuit and at the same time enjoy the convenience and versatility offered by RPi. The CM4S comes in the SODIMM size, hence all that you need to embed the PCB in the target circuit is a regular RAM socket.
The heart of the CM4S is the Broadcom BCM2711 chip, which features a quad-core ARM Cortex-A72 CPU clocked at up to 1.5 GHz – a solution that provides significant computing power in a compact form factor. The CM4S is available in various configurations of RAM: 1 GB, 2 GB, 4 GB, or 8 GB. Unlike full-size models, these boards can be equipped with integrated eMMC mass storage (8 GB, 16 GB, or 32 GB). This gives the user a wide range of options for tailoring the device to suit the needs of various projects.
Note that, unlike the CM4, the Compute Module 4S is not equipped with a Wi-Fi or Bluetooth wireless connectivity module. Nonetheless, it supports HDMI, I2C, MIPI (CSI for camera and DSI for display), PCM, PWM, SPI, UART and USB (2.0) interfaces. This selection of ports creates the possibility of connecting a wide range of peripherals, including, of course, communication modules.
