Dupont Jumper Wire Assortment (Male-to-Male)

category: Bench stock
qty: ~100 (per Alex's direct count — originally logged as "~20+" based only on what was visible loose in the intake photo)
status: owned / in use
maker: Generic/unbranded (no packaging or maker's mark supplied — a loose working bundle, not a boxed kit)

Overview

A loose bundle of male-to-male Dupont jumper wires in assorted colors (red, yellow, blue, white, gray, black, orange, teal, purple observed) and lengths, used to make breadboard-to-breadboard and breadboard-to-module connections. Every wire end visible in the supplied photo terminates in an exposed pin (male) — no female (socket) ends were identified in the bundle, so treat this as a male-male-only assortment until/unless female-terminated wires are confirmed and added.

Key specs

Connector type: male pin header, both ends, on every wire examined (2.54mm/0.1in pitch, breadboard/pin-header compatible)
Colors observed: red, yellow, blue, white, gray, black, orange, teal, purple
Wire gauge/rating: not printed/measurable from the supplied photo — treat as standard 26-28AWG stranded hookup wire typical of this wire class, signal/logic-level current only, not verified

Pinout

N/A — passive point-to-point wires, no fixed pin mapping.

Wiring / typical usage

Standard breadboard prototyping connections: MCU GPIO to breadboard rail/row, module pin to breadboard row, or breadboard rail to rail. Since this bundle is male-male only, connecting directly to a female header (e.g. some MCU pin sockets) needs either a male-female wire (not confirmed present in this bundle) or an intermediate breadboard hop.

Code / libraries

N/A — passive wiring.

Source material

Identified directly from the supplied photo — connector type (male, both ends) and color variety confirmed visually, no external source needed for a generic wire bundle.
Product photo: /inventory/dupont-jumper-wire-assortment/product-photo.jpg — a tighter crop of the as-supplied photo showing the wire ends and color variety clearly.

Verification

Identified from the supplied photo only — connector gender confirmed visually (all ends show exposed pins), gauge/current rating is a typical-for-class assumption, not measured or printed anywhere on the wires themselves.

Notes / gotchas

Confirmed male-male only from the photo — if a project needs a male-female or female-female jumper, check before assuming this bundle has one.
No printed length/gauge spec — if a specific project needs a rated wire (e.g. for the motor rather than logic signals), don’t assume these are adequate without checking gauge against the load current.
