The EDATEC ED-SBC3300 is a powerful industrial Mini-ITX motherboard, created to optimize the Raspberry Pi Compute Module 5 (CM5) performance. The device has a large number of ports and headers, such as RS232 and RS485 interfaces, HDMI 2.1, LVDS display interfaces, 7xUSB 3.0/2.0 ports, up to 2xGigabit Ethernet connections. With the addition of the more recent Raspberry Pi CM5, the EDATEC ED-SBC3300 is a more modern version of the EDATEC ED-SBC2300, which was based on the Raspberry Pi CM4.
The series includes four models: ED-SBC3310, ED-SBC3311, ED-SBC3320, and ED-SBC3321, based on the Raspberry Pi CM5 System on Module (SoM), featuring the Broadcom BCM2712 SoC, offering high-performance processing and connectivity options tailored for diverse use cases.

Except for the Raspberry Pi Compute Module 5 (CM5), the hardware is mostly unchanged. Both the Raspberry Pi OS 32-bit/64-bit Lite and Desktop versions are available, and EDATEC offers the required drivers, demonstrating consistent software support. Nonetheless, there are a few recognized CM5-specific problems that need more focus:
- The RS485 function is currently unavailable and needs manual modifications by EDATEC to enable it, though this service is offered upon request.
- Some mSATA SSDs exhibit slow read speeds.
- Only two RS232 ports (JCOM1 and JCOM2) are fully functional at present, with ongoing software development to enable the additional RS232 ports (JCOM3–JCOM6).
Pre-configured models such as the ED-SBC3310-10432-PH and ED-SBC3310-10832-PH are available on AliExpress for $233.00 and $275.00, respectively. These include WiFi, Bluetooth, PoE, a heatsink, and 4GB or 8GB RAM with 32GB eMMC storage. For those who require the power of the Raspberry Pi Compute Module 5 in a mini-ITX form factor, the EDATEC ED-SBC3300 offers a stable and adaptable industrial platform. It is a great solution for embedded, industrial, and Internet of Things applications due to its many connectivity features, which include USB ports, Gigabit Ethernet, and extension headers.
