Avalue Technology’s ACPI-PI is a Raspberry Pi-compatible, industrial SBC family, starting with the ACP-3566-PI and ACP-IMX8-PI, designed for edge computing and industrial IoT applications with long-term supply.
The ACP-3566-PI is built around a Rockchip RK3566 quad-core Cortex-A55 processor with 4GB RAM and 32GB eMMC. Other features include 4K HDMI output, MIPI DSI/CSI, GbE LAN, Wi-Fi, Bluetooth, and a 40-pin GPIO header for UART, SPI, I2C, and RS-232/RS-485 expansion. The ACP-IMX8-PI, on the other hand, is built around an NXP i.MX8M Mini processor (quad Cortex-A53 + Cortex-M4), 4GB LPDDR4, 32GB eMMC, HDMI, MIPI display, and camera support. Additionally, it has four USB 2.0 ports, an SD slot, an audio jack, and GPIO/UART expansion. Measuring 85×55 mm, both boards can be used for smart retail, healthcare, factory automation, and AI edge deployments.

Going through the specification, it seemed like the company was in a hurry to get the products out and didn’t care much about the details. For instance, the datasheet is just a single-page document with a poorly formatted table and minimal technical details. On top of that, the ACP-3566-PI’s datasheet doesn’t mention the RAM type at all. The ACP-IMX8-PI doesn’t come with built-in Wi-Fi, and it only mentions “USB Wi-Fi connector (supports USB Wi-Fi module).” Honestly, this is quite disappointing coming from a company that has been in the industry for over 25 years.
Another disappointment is the lack of consistency in temperature specifications. The press release page mentions that the boards support -20°C to 85°C. But the datasheet for the ACP-3566-PI liss an operating temperature range of only 0°C to 60°C. To make matters worse, the datasheet for the ACP-IMX8-PI completely removes the operating temperature part.
In terms of software, the ACP-IMX8-PI supports Yocto 4.0 (Linux). The ACP-3566-PI runs Debian 10 (Linux) out of the box. Avalue lists an RKNN Model Zoo testing repository for the ACP-3566-PI on their GitHub, under the Rockchip Edge AI category. However, it does not include a complete AI SDK, board support package, or development tools.
Previously, we have written about the Radxa ROCK 4D, the ECB30-P4T13IA5ME8G-I, and Muse Pi Pro, all are Raspberry Pi compatible SBCs with powerful SoCs, an industrial operating temperature range of -40 to 85°C, and cutting-edge design with support for onboard M.2 and mini PCIe slots. If you are looking for a powerful, compact, and feature-rich industrial SBC, you can always check out various Raspberry Pi-compatible industrial development boards on CNX Software.
Avalue did not provide pricing information for the ACP-3566-PI or the ACP-IMX8-PI. The ACP-3566-PI has a little more information available through its manual, which can be downloaded from the download section of the product’s page. Additional information may also be found in the press release.
