Description

Thundercomm TurboX

TM

D845 System on Module(SOM) is a high performance intelligent module, integrating

Android or Linux system, based on Qualcomm SDA845 processor. It integrates the advanced 10 nm Fin FET
process, a customized 64-bit ARM v8-compliant Octacore Qualcomm Kryo 385 applications processor.

TurboX D845 SOM supports short-range wireless communication through Wi-Fi 802.11 a/b/g/n/ac and BT5.0.
This SOM supports 3840*2400@60fps display, it can connect 4 x camera modules, and integrating multiple
audio and video input/output interfaces. This SOM provides a variety of GPIO, I2C, UART and SPI standard
interfaces. In addition, it supports two MIPI-DSI, four MIPI-CSI and SOM common standard protocol
interfaces such as USB3.1, PCIE2.1/3.0, I2S and SLIMBUS.

TurboX D845 SOM provides convenient and stable system solution for IOT field, it can be embedded into the
device on VR/AR, Drone, Robot, Smart Camera, AI devices, and any other connecting fields. The size of
module is 37mm x 60mm x 7.1mm, weight 10.3g, with 336PINs.
