Antmicro releases open-source hardware Snapdragon 845 baseboard designed with KiCad

Antmicro team has released an open-source hardware baseboard for Quectel SA800U-WF System-on-Module powered by Qualcomm Snapdragon 845 octa-core processor, which they designed with KiCad open-source EDA tool.

The baseboard supports NVMe storage and offers Micro HDMI and MIPI DSI video interfaces, Gigabit Ethernet with PoE support, USB 3.1 Type-C interfaces, and other I/Os, plus three separate power inputs. The company expects the design to serve as a starting point for building portable smart assistants, kiosks, VR/AR or smart screens, and more.

Snapdragon 845 baseboard block diagram

You’ll find the KiCad and PDF schematics and other information on Github with everything released under a permissive Apache 2.0 license. Antmicro further highlights the design is completely free (zero cost license and royalty-free platform), and it appears they’ve done this to promote their services which include “complete hardware, software, AI, OTA and fleet management development services, from a product’s inception to mass deployment”. In any case, you are free to build on the design or ask Antmicro to help.

The Quectel SA800U-WF module ships with Android 9.0 or 10.0, but other companies are offering Linux BSPs for their Snapdragon 845-powered products, and that includes Qualcomm’s own Robotics RB3 Development Platform that runs Debian or OpenEmbedded. Antmicro also highlights support for AI-oriented frameworks such as TensorFlow, TensorFlow Lite or Caffe2 with processing accelerated with the GPU and Hexagon Vector Extensions.

It does not look like Antmicro intends to sell the board based on the information provided in the announcement.

Why even bother? Qualcomm is against properly supporting both amateur and commercial clients.

Very similar specs to my 5 year old phone, but with lots physical ports so no need for usb dock

Now if they updated the software and sold it like a RPI4 COM for £10-£15 more. Only a pipe dream.

When is written UFS can u specify which type? 2.0-3.0-3.1?

And also the price because I think will be very expensive.

Couldn’t care less about UFS, but the quad 2.8GHz Cortex-A75 + M.2 (and quad 1.8GHz Cortex-A55) sounds interesting.
Now, if they had just put the GbE on PCIe2.0 instead of PCIe3.0, they could have put the M.2 on PCIe3.0 instead of PCIe2.0!
-Still, this board beats most other boards, just because it offers a PCIe connection to the outside world.
This board does make Antmicro a company I’ll have in mind – and maybe I’ll even get one of these boards.

> if they had just put the GbE on PCIe2.0 instead of PCIe3.0

Exactly my thoughts but since I assume they’re not stupid I thought ‘block diagram wrong’.

Anyway: if I’m not wrong it’s only one lane per PCIe controller but ofc Gen3 speed on the M.2 slot is twice as fast as Gen2 (both bandwidth and latency).
