Assembly and use

Configuration and sourcing

IoT Design Shop modified v1 build; v2 tracked separately within family.

v1 wiki describes 18 servo channels and a Nano RP2040 Connect protoboard with headers/wiring; full mechanical BOM still marked unfinished. The electronics guide specifies a 6 cm × 4 cm universal protoboard, male and female 0.1-inch headers, soldered wiring and external 5 V connections. A digital multimeter is needed for continuity checks; supply capacity and the complete servo/mechanical shopping list remain unresolved. [S001] [S002] [S003] [S004] [S005] [S006] [S007] [S008]

Use the modified v1 printable geometry with its matching controller layout; follow finger/wrist/tendon instructions and continuity-check hand-wired board. [S001] [S002] [S003] [S004] [S005] [S006] [S007] [S008]

Integration

Original videos use Arduino Mega; IoT Design Shop build uses Nano RP2040 Connect. Neither is evidence for v2 controller compatibility. [S001] [S002] [S003] [S004] [S005] [S006] [S007] [S008]

Design limits and source rights

Reconcile servo models/counts and full mechanical BOM; locate and verify firmware matching the modified v1 controller and pin layout; the reviewed evidence does not establish that matched source set; The supplied v2 early-access material does not establish a complete, validated successor build within this review. [S001] [S002] [S003] [S004] [S005] [S006] [S007] [S008]

The v1 website describes the DexHand and associated projects and documentation under CC BY-NC-SA 4.0, including a noncommercial restriction. Its applicability to the specific modified geometry still needs confirmation. The v2 repository supplies CERN-OHL-S-2.0, but its README also requests restricted redistribution outside NVIDIA. That tension needs maintainer clarification. Do not transfer v2 terms to v1 geometry. [S001] [S002] [S003] [S004] [S005] [S006] [S007] [S008]

This is a source-researched design profile. We have not assembled or tested this configuration; no complete current setup price is established.

Cost

No current, complete configuration-specific build cost has been established for this profile.
