Android, LTE and HDMI on one board.
Single board computer built around the Quectel SC200E smart module with LTE, Wi-Fi/BT and GNSS. It adds cameras, a touch LCD, HDMI output, Ethernet, NFC, BLE, sensors, audio and Li-Po battery charging, with a separate extension board. Designed in Altium with controlled-impedance routing.
The board
The main board measures 6008 × 2445 mil and is built on 8 layers (5 signal and 3 plane) with a finished thickness of 40.3 mil. It carries 892 components and was designed in Altium together with its DSI-to-HDMI extension board. High-speed interfaces include USB-C 3.1, HDMI, MIPI DSI and CSI, plus RF feeds for LTE, GNSS and Wi-Fi/BT.
All layers of the main board combined: RF feed lines for the LTE, GNSS and Wi-Fi/BT antennas, and USB-C 3.1 and HDMI differential pairs routed against solid reference planes.
