Avalue ACP-3588 Rockchip RK3588 SBC with 32GB eMMC, Dual HDMI, LVDS and eDP

Multi-screen signage, video walls and operator panels need more display outputs and decode headroom than a typical Arm board offers, often alongside serial and CAN links to the equipment around them. The ACP-3588 is Avalue’s Rockchip RK3588 SBC for that work, built as a core board on a carrier board measuring 150 x 125 mm, with 32 GB of eMMC, two HDMI 2.1 outputs, LVDS, eDP and an HDMI input.

The Rockchip RK3588 combines four Arm Cortex-A76 cores with four Cortex-A55 cores at up to 2.4 GHz, so heavy rendering and decode run on the large cores while background services stay on the efficient ones. The ACP-3588 carries 4 GB of LPDDR4 memory soldered to the board and 32 GB of eMMC for the operating system, and Avalue supplies it with Android 12. Its AI SDK is published on GitHub for developers working with the Rockchip toolchain.

Display is the standout. Two HDMI 2.1 ports drive screens at up to 8K at 60 Hz or 4K at 120 Hz, LVDS and eDP connect internal panels, and an HDMI input accepts a 4K source at 60 Hz. Storage expands through an M.2 2280 M-key slot with PCIe x4 for an NVMe SSD and two SATA 3.0 ports. For the equipment around it there are four RS-232 ports on internal headers, one CAN port on a terminal block, a 12-line GPIO header, a four-lane MIPI CSI camera input, one GbE RJ45 port and five USB ports: USB 3.0 and USB 2.0 Type-A, a USB OTG Type-C and two internal USB 2.0 headers. Dual-band Wi-Fi 6 is onboard, with line-out and microphone audio.

The ACP-3588 runs from a 12 V DC supply on a barrel connector and cools through a passive heatsink, with an operating range of -5 to 65 °C and 5 to 90% non-condensing humidity. That suits indoor signage cabinets, kiosks, retail displays and line-side HMIs in controlled environments, with CE and FCC compliance for equipment builders.
