This folder contains the completed Step 4 software design package. It starts from the released Step 3 five-sheet schematic, keeps every Step 2 optical/mechanical lock, separates high-current, digital-control and analog/TIA placement, routes the board, adds a B.Cu ground plane and stitching vias, exports fabrication files, generates a detailed PCB STEP, and inserts that STEP into the mechanical assembly.

UGrow3 Routed: common questions
What microcontroller does the UGrow3 Routed use?
The UGrow3 Routed is built around the ATTINY1616-SN, from the AVR/Arduino family.
How big is the UGrow3 Routed PCB?
The UGrow3 Routed measures 70 × 45 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the UGrow3 Routed?
77 components, from 44 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 UGrow3 Routed design files?
