ODYSSEY – STM32MP157C
Reference Guide
Overview
Description
The ODYSSEY – STM32MP157C is a single board computer that is based on STM32MP157C, a dual-core
Arm® Cortex®-A7 processor operating at 650Mhz. The processor also integrates an Arm®
Cortex®-M4 coprocessor, which makes it suitable for real-time tasks. The ODYSSEY – STM32MP157C
is created in a form of SoM (System-On-Module) with a carrier board. The SoM consists of an MPU,
PMIC, RAM and the carrier board is in Raspberry Pi form factor. The carrier board includes all the
necessary peripherals including Gigabit Ethernet, Wi-Fi/BLE, DC Power，USB Hosts, USB-C, MIPI-DSI,
DVP for camera, Audio, etc. With this board, customers can evaluate the SoM and deploy the SoM on
their own carrier board quickly and easily.
Features
• Dual-Core Arm® Cortex®-A7 Processor with Cortex®-M4 Integrated
• SoM (System-On-Module) includes MPU, PMIC, RAM
• Raspberry Pi 40-Pin Compatible Carrier Board
