We were expecting Raspberry Pi Compute Module 4 sometimes next year, but Raspberry Pi Trading Limited managed to launch the new module much earlier, as Raspberry Pi CM4 and CM4Lite modules have just been launched with a new, much more compact form factor incompatible with the earlier Compute Modules, an I/O board making use of the new features, and a choice of 32 models with variations in terms of memory and storage capacity, as well as the presence or lack thereof of a WiFi and Bluetooth wireless module.

The Raspberry Pi Computer Module 4 also comes with an optional I/O board and an antenna (kit).
There’s also a PoE header, a USB header with two USB 2.0 interfaces, a micro USB port for firmware updates, some configuration jumpers (for wireless, EEPROM writing…), and a 12V DC jack.

RPTL standards for “Raspberry Pi Trading Limited” and I suppose it’s some kind of ordering code. We can see from the table some of the modules will only be available in bulk with a minimum order quantity, mostly RPI CM4 systems-on-module without wireless module. Raspberry Pi guarantees the availability of the CM4 until at least January 2028. The IO board will sell for $35, and the antenna for $5.
You’ll find the module for purchase on distributors like RS Components, Cytron, Element14, Seeed Studio, and many others.
