THE Raspberry Pi Foundation announced this Monday (19) O Raspberry Pi Compute Module 4. Technically, the card is very similar to the Raspberry Pi 4 launched in June 2019, but it has a format that makes it suitable for industrial applications.
Such a device makes a lot of sense. The traditional Raspberry Pi can be directed to a multitude of educational projects or applications developed by enthusiasts, for example. It is also possible to use it in industrial or commercial applications. The problem is that, depending on the purpose, the device ports may be disruptive or useless.
Models such as the Raspberry Pi Compute Module 4 fill this gap as they consist of small plates that do not include USB or Gigabit Ethernet connectors, for example, and can be more easily installed on equipment that does not require these features.
This does not mean that the novelty has no firepower. The Raspberry Pi Compute Module 4 features the Broadcom BCM2711 processor, a 64-bit quad-core chip (four Cortex-A72 1.5 GHz cores) that also appears on the Raspberry Pi 4.
Another feature inherited from the Raspberry Pi 4 is the 500 MHz VideoCore VI GPU, capable of working with H.265 (HEVC) standards for decoding video at up to 4K and 60 fps or H.264 (AVC) for 1080p and 60 fps . Still in terms of video, the board has two HDMI interfaces that support resolutions up to 4K.
The amount of RAM (LPDDR4-3200) ranges from 1 GB to 8 GB. There are also storage options, from none (this is the “Lite” version) to up to 32 GB of eMMC.
You can also choose whether the device will feature 802.11ac Wi-Fi and Bluetooth 5.0.
In the end, there are so many optional features that the Raspberry Pi Compute Module 4 ends up with 32 variations. The cheapest one costs $ 25 and brings 1 GB of RAM. The most expensive, priced at $ 90, has 8 GB of RAM, 32 GB of storage and Wi-Fi. This table contains all versions and their respective prices (PDF).
For those who need the convenience of multiple ports, the Raspberry Pi Foundation has announced the Compute Module IO Board, larger card that accommodates the Compute Module 4 and features such as two HDMI ports, Gigabit Ethernet connection, two USB 2.0 ports and connectors for camera or screen.
The Compute Module IO Board alone costs $ 35.
