**NOTE**: This build is alpha quality and is for experimental use. It is [missing features and has known issues](https://github.com/adafruit/circuitpython/labels/broadcom).

The **Raspberry Pi Compute Module 4** is based on the [Raspberry Pi 4 Model B](http://www.adafruit.com/product/4297), but in a smaller form factor - perfect for embedding into products or projects without the bulk of a classic Raspberry Pi. You get all the computational power of Raspberry Pi 4 in a compact form factor for deeply embedded applications. The CM4 incorporates the same quad-core ARM Cortex-A72 processor, dual video output, gigabit Ethernet, UART, I2C, SPI, I2S, and a few PWM for good measure.

This module is available in **multiple variants**, with a range of RAM and eMMC Flash options, and with or without wireless connectivity. The modules are available with 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM with optional storage of 8GB, 16GB or 32GB eMMC Flash. The wireless option includes 2.4GHz and 5GHz 802.11b/g/n/ac wireless LAN and Bluetooth 5.0 for BT classic and BTLE support.

The Raspberry Pi 4 Model B is the newest Raspberry Pi computer made, and the Pi Foundation knows you can always make a good thing better! And what could make the Pi 4 better than the 3? How about a faster processor, USB 3.0 ports, and updated Gigabit Ethernet chip with PoE capability? Good guess - that's exactly what they did!

At first glance, the Pi Zero isn't much. It just looks like a slimmed down version of the Raspberry Pi we know and love. But when we started to think of the possibilities - and what a well-chosen set of accessories could add - we realized the appeal. And then we saw the price...could it be true? Yes!

This is the slimmest, most pared down Raspberry Pi to date. It's kind of like the little cousin to the Pi 2 - with just a micro SD card slot, a mini HDMI port, two micro USB ports (one for power, one for USB), and 512MB of RAM. It has a single-core 1 GHz processor chip, similar to the Pi A+ and B+.
