Ugrow3 is an open-source printed circuit board by Dhyan-M, from the Dhyan-M/MuGrow-TA repository on GitHub. It is a 2-layer board of 70 × 45 mm with 81 parts on 48 nets.
It is built around the MCP6004-I/SL, 24LC256-I/SN and MCP1700-3302E/TT. Its parts include 28 resistors, 18 capacitors, 8 connectors, 7 diodes and 6 transistors. It belongs with the AVR (ATmega, ATtiny) boards of this library.
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.kicad_pro in KiCad. The routed board is ugrow3.kicad_pcb; an identical release copy is UGrow3_Routed.kicad_pcb.UGrow3_Routing_Top.png, UGrow3_Placement_Regions.png and UGrow3_Ground_Plane.png for the routing handoff.UGrow3_Final_Routed_PCB.step into Fusion for the PCB alone, or open UGrow3_Fusion_Assembly_with_Routed_PCB.step for the synchronized mechanical assembly.| Output | File |

It measures 70 × 45 mm and has 2 copper layers, 1.6 mm thick.
81 parts, built around the MCP6004-I/SL, 24LC256-I/SN and MCP1700-3302E/TT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Dhyan-M/MuGrow-TA repository on GitHub, at the commit this page was made from: the board is Step2_PCB_Mechanical/ugrow3.kicad_pcb and its schematic Step2_PCB_Mechanical/mcu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Dhyan-M before reusing the design.
