Overview
The Coral Dev Board is a single-board computer that's ideal when you need to perform fast machine learning (ML)
inferencing in a small form factor. You can use the Dev Board to prototype your embedded system and then scale to
production using the on-board Coral System-on-Module (SoM) combined with your custom PCB hardware.
The SoM provides a fully-integrated system, including NXP's iMX8M system-on-chip (SoC), eMMC memory, LPDDR4
RAM, Wi-Fi, and Bluetooth, but its unique power comes from Google's Edge TPU coprocessor. The Edge TPU is a small
ASIC designed by Google that provides high performance ML inferencing with a low power cost. For example, it can
execute state-of-the-art mobile vision models such as MobileNet v2 at almost 400 FPS, in a power efficient manner.
The baseboard provides all the peripheral connections you need to prototype a project, including USB 2.0/3.0 ports, DSI
display interface, CSI-2 camera interface, Ethernet port, speaker terminals, and a 40-pin I/O header.
Key benefits of the Dev Board:
High-speed and low-power ML inferencing (4 TOPS @ 2W)
A complete Linux system (running Mendel, a Debian derivative)
Prototyping and evaluation board for the small Coral SoM (40 x 48mm)
