This Raspberry Pi Computing Module 4 (CM4) Usually used in deep embedded applications that require a custom carrier board. Compute Module 4 is powered by a quad-core ARM Cortex-A72 processor Raspberry Pi 4 Becomes a much smaller package. MinCab, the smallest and smallest carrier board of the Raspberry Pi CM4 board, has just been released. It comes from Ivan Kuleshow of Uptime Labs, Also responsible for Computing blade server.
MinCab hardware is just that-a mini carrier board. It provides the smallest interface with the outside world, allowing you to make a simple connection with the CM4 board. The board uses the USB-C connector to power the CM4 and disconnect some GPIO connections. Specifically, we provide 5V, 3.3V and GND signals on the MinCab board pad. More specifically, the available GPIO pins are IO2, IO3, IO4, IO12, IO13, IO14, IO15, and IO18. These pins work under standard 3.3V logic, but can also be used for I2C, serial (Tx/Rx) and pulse width modulation (PWM).
MinCab PCB achieves all of this, while only using two available one split line.Another breakthrough is available, but as Mentioned by Kuleshov via Twitter conversation, Add-on boards that use spare connectors will require a “bridging” between the two connectors. The board has two M3 screw points that can be used to mechanically connect the board to CM4. Now, MinCab represents a unique way of using connections in an efficient way, encapsulated in a small form factor.
Ideally, the MinCab board will be used in applications such as smart home systems, in which Bluetooth and Wi-Fi connections are essential. If our CM4 project requires a little processing power, the Broadcom BCM2711 processor can run any Linux application.
If you want to know the availability of the MinCab board, its manufacturer Uptime Lab has not officially launched it on the website. For now, the project appears to be just a prototype, at least until the owners of Uptime Lab decide to mass-produce it for a wider audience.
