1.1 Overview
The sTPC-SXXX-3568B Series (production models sTPC-S101-3568B / S156-3568B / S215-3568B) is a fanless ARM Touch Panel PC (PANEL PC) built on the Rockchip RK3568 platform, covering 10.1″ / 15.6″ / 21.5″ screen sizes.
Each unit has a full-flat front and a rear expansion bay: the front is a multi-point capacitive touch screen in a plastic bezel; the raised bay in the centre of the back carries the I/O in two rows — power, serial, USB, HDMI, LAN, antennas and SIM slots — with VESA mounting holes in the four corners. Both VESA bracket and panel-cutout (embedded) mounting are supported, for production-line dashboards, equipment HMIs and self-service terminals.
Features
- Rockchip RK3568: 4 × Cortex-A55 @2.0GHz, 1TOPS NPU
- All on-board I/O design, rich interface set, no need to open the unit for maintenance
- Fanless design, supports VESA and embedded mounting
