Special Mark

Product Overview

QuecPi Alpha is an intelligent ecological single-board computer developed by Quectel based on the high-performance 8-core 64-bit processor from Qualcomm QCS6490 (with computing power of up to 12.15 TOPS) and the Qualcomm AdrenoTM 642L/643 GPU. It has 8 GB LPDDR4X memory, adopts USB Type-C power supply interface, and can be externally connected to eMMC and SSD. It also supports Wi-Fi 2.4 & 5 G, IEEE 802.11a/b/g/n/ac and Bluetooth 5.0, as well as dual displays (DP and LCM or DP and HDMI). With strong performance and rich multimedia functions, it can meet your requirements for high data rate, multimedia functions and computing power in industrial and consumer applications.

QuecPi Alpha integrates abundant interfaces, which significantly expands its application in M2M field. It can also be widely used in industries and devices such as edge computing, robotics, industrial control, multimedia terminals, digital billboards, intelligent security systems and industrial-grade PDA, covering various sectors across the entire AIoT field.

QuecPi Alpha supports Linux/Ubuntu* operating systems, which can meet the requirements of algorithm prototype verification and inference application development.
