RPC-21WA
Series: RPC
The Avalue RPC-21WA is a 21.5" ARM-based interactive panel PC built on the Rockchip RK3576S (quad Cortex-A53 + quad Cortex-A72) with a Mali-G52 MC3 GPU, designed for digital signage, kiosk, self-service and interactive display applications. It features a 1920 x 1080 FHD PCAP multi-touch panel supporting up to 10 points, a four-side interactive LED halo light bar for status indication, and a G-sensor for auto-screen rotation. With 4GB DDR RAM, 32GB eMMC storage, USB 3.0/2.0/Type-C, HDMI-in, GbE, a quad-microphone array with noise reduction and echo cancellation, and fanless operation from 0 to 40 degrees C, it runs Android 14/16 with Google EDLA support. Powered by 12V DC or Powered LAN (IEEE 802.3bt), it is part of a scalable 21.5 to 32 inch series. TSL Automation Solutions supplies and supports the RPC-21WA across India.
