This page carries an **interactive 3D model** of the assembled board plus+schematic and layout views, so you can inspect the real design without opening Fusion.++Designed by **Adonis** in Autodesk Fusion 360 Electronics (Main project). The board integrates+**14 Adom machine pins** (`MP1` to `MP14`) so it presses into the Adom modular stack, mating with+machine contacts on adjacent boards.++## The 3D model above++The interactive viewer shows the fully-placed board: green soldermask, gold plating, the BQ25792+charger IC and power stage, passives, connectors, and the **Adom machine pins standing vertical**+around the board edges. Drag to orbit, scroll to zoom. Colors are the real Fusion materials,+preserved through the STEP to GLB pipeline.++## What the BQ25792 does++| Feature | Detail |+|---|---|+| Type | I2C-controlled buck-boost battery charger |+| Cell count | 1 to 4 cells in series (1S to 4S) |+| Charge current | Up to 5 A |+| Input | USB-C and generic DC, wide input range with input current optimizer |+| Power path | Integrated, so the system runs while charging |+| Telemetry | On-chip 16-bit ADC (voltage, current, temperature) |+| Extras | Dual-input selection, MPPT for solar, integrated FETs |++## Board (Fusion, v222)++| Property | Value |+|---|---|+| Outline | 69.17 x 52.10 mm |+| Components | 109 (108 top, 1 bottom) |+| Signals | 50 nets (3 airwires still to route) |+| Pads | 304 |+| Vias | 88 |+| Holes | 176 |+| Adom machine pins | 14 (MP1 to MP14) |++## Adom machine pins++The board uses the Adom **press-fit machine pin** system for board-to-board stacking. Each pin+presses into a plated through-hole and mates with a machine contact on a stacked board.
