Introducing the Hat Ai! Dual from Pineboards – the first Google Coral Dual Edge TPU integration in Raspberry Pi 5 ecosystem, designed to be mounted underneath your Pi!

The dedicated M.2 E-Key slot for an E-Key Google Coral Dual Edge TPU (not included) makes it an indispensable tool for AI enthusiasts and professionals alike.

The board uses a PCIe packet switch to enable sharing of the single PCIe lane between the two TPUs on the Dual Edge module. The processing performance is up to 2x the standard (single) TPU since most data transfers occur only when the TensorFlow models are being loaded by your application

We also stock a version for the standard Coral Edge (single) TPU.

We also stock a layer case for this HAT!

Coral Dual Edge TPU and Raspberry Pi 5 not included

PCIe FPC Bundles now available

In case you are thinking about integrating this board into your custom project, don’t overlook the optionalPineboards PCIe FPC Bundle. Utilising the 100mm ribbon cable will provide you with added flexibility during the installation process of our boards.

We now stock an XL version of the bundle too!

Features

• Designed for Raspberry Pi 5: Seamless integration with the Raspberry Pi 5
• Designed to mount under your Pi: our Hat Ai! does not block GPIO access, just like the HatDrive! Bottom
• Coral TPU Compatibility: Supports the Coral Dual Edge TPU in M.2 format with an E-key interface.
• Includes a PCIe packet switch: ASM1182e enables sharing of the single PCIe lane between two TPUs. The processing performance is up to 2x the standard TPU since most data transfers occur only when the TensorFlow models are being loaded by your application
• LED Indicator: Features 1 LED for monitoring the power input of the board
• Compliant Power System with M.2 Standard: Features an integrated voltage regulator capable of delivering up to 3A for the 3.3V power rail, adhering to the M.2 (NGFF) standard.
• Easy Dual Edge TPU Installation: Quick and secure installation for M.2 Coral Dual Edge TPU (2230) using a specially designed metal bracket.
• Premium Quality Components: Constructed with top-grade electronic components and a durable 4-layer PCB.
