Avalue ACP-3566-PI-A1-1R Rockchip RK3566 Raspberry Pi Alternative SBC with 4GB Memory and 32GB eMMC

A Raspberry Pi is often where an embedded idea is proven, but production needs a board with a stated lifecycle, CE and FCC compliance and a supplier who can quote the same build next year. The ACP-3566-PI-A1-1R is that build in the Avalue ACP-3566-PI series, a Rockchip RK3566 Raspberry Pi alternative that keeps the 85 x 55 mm footprint and 40-pin header while Avalue backs it with a long lifecycle guarantee.

The Rockchip RK3566 provides four Arm Cortex-A55 cores at up to 1.8 GHz, which in practice covers Linux applications, HTML5 signage, protocol conversion and light control logic. Memory is 4 GB, soldered to the board, so there is no memory module to source or seat, and 32 GB of eMMC holds the operating system and application. The board ships with Debian 10, and Avalue publishes its AI SDK on GitHub for teams building with the Rockchip toolchain.

Connectivity follows the familiar layout. One GbE RJ45 port handles the network, with one USB 3.0, two USB 2.0 and one USB 2.0 OTG port on Type-A connectors, plus an internal USB header. HDMI 2.0 drives a 4K display, an internal MIPI DSI connector takes an LCD panel and a two-lane MIPI CSI connector takes a camera module. Dual-band 802.11ac Wi-Fi is onboard, and the 40-pin header can be set as GPIO, UART, I2C or SPI. A microSD slot accepts cards up to 64 GB.

Power is 5 V at 3 A over USB-C, which keeps the cable count low in signage players and compact enclosures. The ACP-3566-PI-A1-1R cools through a passive heatsink with no fan and is rated for 0 to 60 °C operation, so it suits offices, retail units, kiosks and control cabinets in heated or air-conditioned spaces. For colder sites, Avalue’s 3.5″ Arm boards cover wider temperature ranges.
