I hope that the long-awaited Raspberry Fall 4 calculation module is finally released!

I have been looking forward to the release of CM4, although PI4 is very powerful, demand is very strong, but you can only use the entire board to do some learning and system development, many products are not suitable for PI4. Today, CM4 is finally released, look at it looks: Positive picture: Main performance indicators: 1.5GHz Quad-Core 64-Bit ARM Cortex-A72 CPU VideoCore Vi Graphics, Supporting OpenGL ES 3.X 4kp60 hardware decode of h.265 (hevc) video VIDEO 1080p60 Hardware Decode, and 1080p30 hardware encode of h.264 (avc) Video Dual HDMI Interfaces, At Resolutions Up to 4K SINGLE-LANE PCI Express 2.0 Interface Dual Mipi DSI DISPLAY, AND DUAL MIPI CSI-2 Camera Interfaces 1GB, 2GB, 4GB OR 8GB LPDDR4-3200 SDRAM Optional 8GB, 16GB or 32GB EMMC FLASH STORAGE Optional 2.4GHz and 5GHz IEEE 802.11B / g / N / AC Wireless Lan and Bluetooth 5.0 Gigabit Ethernet Phy with IEEE 1588 Support 28 GPIO Pins, with Up to 6 × UART, 6 × I2C and 5 × SPI Very powerful core computing module also gives a very flexible function ~ price option, according to its EMM, DRAM size and whether there is WiFi, a total of 32 different variants, see below: This CM4 abandoned the mode of the previous version of the memory module to expand two high-speed sockets (a socket for power supply and low speed signal connections, and another socket for high speed signal connection), more smart, compact. High-speed, high-density connector behind it behind: The size of the board is only 55mm * 40mm size (no matter which configuration). With this core module, you can flexibly design your own board and make full use of the most cost-effective products, such as DIY PC, Terminal, Industrial Control Machine, etc. (Soviet " Use it to make a product). In order to help developers quickly, accurately design their peripheral motherboards, the Raspberry Pist also provides an IO board for an evaluation of open source (with Kicad painting). Based on this design, you only need to cut your platform quickly. . See what functions have this IO reference design board: Two Full-Size HDMI Ports Gigabit Ethernet Jack TWO USB 2.0 Ports Microsd Card Socket (ONLY for Use with Lite, No-Emmc Compute Module 4 Variants) PCI Express Gen 2 x1 Socket Hat Footprint with 40-pin GPIO Connector and poe header 12V Input Via Barrel Jack (Supports Up to 26V IF PCIE Unused) Camera and Display FPC Connectors Real-Time Clock with Battery Backup The effect of the CM4 module is deducted, which looks very small in the core module. The key is that this expansion board is also very cheap - only 35 US dollars, along with the core module of the 乞丐 (I think it is strong enough), and a 60 knife.
