 The [Coral M.2 Accelerator with Dual Edge TPU](https://coral.ai/products/m2-accelerator-dual-edgetpu/) uses an interesting feature of M.2 E-key slots—it uses both lanes that are in the spec to the slot (though most board manufacturers only implement one lane per slot).
 
-The Seaberry board comes with slots that implement both lanes per M.2 E-key slot, though, so this card could work if the device supports it. Sadly, as we've seen with the single TPU ([see issue #44](https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/44)), the Compute Module 4's PCIe implementation is currently incompatible with the Coral PCIe driver.
+There are only a two ways to use this Dual Edge TPU with a Pi natively right now:
 
-Other CM4-pinout-compatible boards _might_ work with it (but nobody's had success yet).
+  - Pineboards makes a [Dual Edge TPU HAT](https://pineboards.io/products/hat-ai-dual-edge-coral-tpu-bundle-for-raspberry-pi-5) which uses a PCIe switch to connect two PCIe lanes to an E-key M.2 slot for the Dual Edge TPU specifically.
+  - The [Seaberry Mini ITX board for CM4](https://pipci.jeffgeerling.com/boards_cm/seaberry.html) comes with slots that implement both lanes per M.2 E-key slot. But the CM4's PCIe implementation seems incompatible with any Coral TPU ([see issue #44](https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/44))
 
 The Raspberry Pi 5 model B may work with it, but right now testing is devoted to the single TPU model, since there are currently no HATs available with a dual-lane M.2 E-key slot (and it's likely there never _will_ be one, unless we can get the singl TPU model working reliably).

+Pineboards offers a [Hat AI! Dual Edge Coral TPU Bundle for Raspberry Pi 5](https://pineboards.io/products/hat-ai-dual-edge-coral-tpu-bundle-for-raspberry-pi-5), which unites a Dual Edge Coral TPU for AI/ML/inference to the Raspberry Pi 5, through a PCIe Switch to support both PCIe lanes for both TPUs.
+
+Most other E-key PCIe HATs only support one PCIe lane, so if you installed a Dual Edge TPU, you would only have access to one of the two TPUs.
+
+Pineboards also includes a Dual Edge TPU with this bundle, so you don't need to source your own from another vendor.
