The portal CNX Software has highlighted the yet-to-be-officially-announced module Raspberry Pi Compute Module 0 (CM0). This is a compact development module in a so-called “castellated” design, based on the SiP (System-in-Package) RP3A0, which is known from models like the Raspberry Pi Zero 2 W and CM3E.
Technical Specifications
From the available materials and documentation, the following specifications are indicated:
- SiP: Raspberry Pi RP3A0
- SoC: Broadcom BCM2710A1
- CPU: quad-core ARM Cortex-A53 @ 1.0 GHz
- GPU: VideoCore IV (OpenGL ES 1.1/2.0)
- VPU: H.264 1080p30 decoding and encoding - RAM: 512 MB LPDDR2
- Storage: Lite version without eMMC, or versions with 8 GB / 16 GB eMMC
- Wireless Connectivity (optional): WiFi 802.11 b/g/n and Bluetooth 4.2 LE, with external u.FL connector
- Interfaces:
- 132 solder pads (castellated holes)
- SDIO (in Lite version)
- HDMI, TV DAC, MIPI DSI (4-lane), parallel DPI
- MIPI CSI for camera
- USB 2.0 (1×)
- Up to 28 GPIO pins
- UART, SPI, and two I²C buses
- PCM audio - Power Supply: 5 V DC
- Dimensions: 39 × 33 mm
- Operating Temperature: –20 to +85 °C
According to information available, there is also an IO board with the embedded CM0 module. This includes HDMI output, MIPI DSI/CSI, a microSD slot (in the Lite version), micro-USB for firmware uploading, a 40-pin GPIO connector, jumpers for disabling wireless modules, an nRPIBOOT jumper, connectors for LEDs, and other components.
Software Support and Pricing
The module should be fully compatible with Raspberry Pi OS, and can be understood as an enhanced version of the Raspberry Pi Zero 2 W with better connectivity thanks to the interfaces available through the castellated pads.
According to available sources, the price is around 18 USD per unit when purchased in larger quantities.
How Was This Module Discovered?
Information about the CM0 emerged thanks to community activity. A tweet from OpenEmbed pointed to product documentation and datasheets that confirmed most of the parameters published by CNX Software. The module has not yet been officially announced by Raspberry Pi, so minor specification changes upon market release cannot be ruled out.
Summary
The Compute Module 0 expands the Raspberry Pi offering with a compact and easily integrable module, designed primarily for embedded systems and industrial applications. Thanks to its castellated design, it can be directly soldered onto custom PCBs, facilitating integration into end devices. If it is indeed released at the indicated price, it could become an attractive choice for IoT projects and industrial deployment.
