About the Spu13 ecp5 carrier PCB

Spu13 ecp5 carrier is an open source RP2040/RP2350 PCB design by pinnacletechnologysolutionsltd, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 95.3 × 110 mm, with 20 components from 9 distinct parts.

Its main chip is the RP2350, from the RP2040/RP2350 family. Other key parts include the LFE5UM-85F. By type, the board carries 12 capacitors, 3 switches, 2 ICs, 2 connectors and 1 crystal.

From the project

Synergetic Processing Unit

A deterministic exact-arithmetic FPGA platform: no floating point, no division and no transcendentals anywhere in the RTL. Arithmetic is exact over Q(√3), A₃₁ and Z[φ]/Lp, and correctness is decided by bit-exact agreement with an independent software oracle rather than by code review.**

Current direction: graphics. A framebuffer-less streaming rasterizer that reached silicon across three consecutive days — first video output (§3.8), first rasterized geometry (§3.9) and depth-resolved geometry (§3.10) in docs/hardwareevidence.md` — each measured against a prediction registered before the…

Spu13 ecp5 carrier: common questions

What microcontroller does the Spu13 ecp5 carrier use?

The Spu13 ecp5 carrier is built around the RP2350, from the RP2040/RP2350 family.

How big is the Spu13 ecp5 carrier PCB?

The Spu13 ecp5 carrier measures 95.3 × 110 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Spu13 ecp5 carrier?

20 components, from 9 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Spu13 ecp5 carrier design files?

From the pinnacletechnologysolutionsltd/SPU repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Spu13 ecp5 carrier design in my own project?

Yes, under the terms of its Apache-2.0 license, which pinnacletechnologysolutionsltd chose for the repository.

Can I test firmware for the Spu13 ecp5 carrier without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
