So we've got every last bit of the RPi Compute Module version of DepthAI working, which is exciting. So now that it's verified, we made the design smaller. We had it big on the first prototype so that white-wire fixes would be easier... and we're glad we did that! We ended up with white wires for:
- 3.5mm Audio
- I2C for the DSI and CSI display/camera for the Raspberry Pi.
Anyways, these are all corrected, and the revised, now smaller, design was ordered on Friday! Here's what it looks like (thanks, Altium 3D view):
And now that this is ordered, we turned our sites on another incarnation of DepthAI that we think will be useful.
But, before we dive into that. Why did we make the Myriad X Module that we made, well, a module?
It's so that we - and you - can easily turn designs that leverage it. It allows the Myriad X to be used on simple, easy, 4-layer boards (instead of the 8-layer HDI and BGA tolerancing and yielf optimization that's required if you use the Myriad X directly).
So, leveraging this module, here's the HAT that we're working on:
You can see the spot for the Myriad X Module right there on top. And then on the left are the FFC (flexible flat cables) connectors to connect to camera modules:
That's right, we're making it so the cameras can be mounted where -you- want them. We'll have some other follow-own Myriad X boards (e.g. non-RPi-specific) that take advantage of this as well. Oh, and on FFC, think of the Raspberry Pi camera little ribbon cable... FFC is the general acronym for that type of cable.
Speaking of which, here are the camera boards:
OV9282 - 720p global-shutter mono camera use for disparity depth:
IMX378 - 12 megapixel color image sensor, supporting 4K video!
And you can see the FFCs on the back bottom of these respectively:
