Half-Size Solderless Breadboard (400 Tie-Point)

Overview

A smaller companion to the full-size 830-point breadboard also in this library — one terminal-strip block (rows a–e and f–j) flanked by two power rails, roughly half the length of the full-size board. Standard for compact builds or when a project only needs a handful of rows. Logged from a direct count Alex gave in chat rather than a photo — flagged accordingly below.

Key specs

• Tie points: 400 (standard for this half-size layout — typical for class, not counted on the actual owned units)
• Terminal strip: 1 block × 5 rows (a–e, f–j) × ~30 columns (typical for this size class)
• Power rails: 2 rails (+ and −), running the board’s length
• Hole pitch: 0.1in / 2.54mm (standard breadboard/DIP pitch)

Pinout

N/A — passive prototyping hardware. Same electrical convention as the full-size breadboard: terminal-strip rows are internally connected in groups of 5, power rails run the full board length.

Wiring / typical usage

Same usage pattern as the full-size board, just less real estate — good for a single small module plus a few jumper connections rather than a multi-chip layout. Pair with the Dupont jumper wire assortment as usual.

Source material

• Quantity (2) and size class (“half”) stated directly by Alex in chat — not yet confirmed against a photo of the actual owned units.
• General 400-tie-point half-size breadboard specs: ProtoSupplies MB-102 400 tie-point breadboard
• Product photo: /inventory/half-size-solderless-breadboard/product-photo.jpg — representative only, NOT the exact owned units (no photo of Alex’s actual half-size breadboards has been supplied yet), sourced 2026-07-25 from https://protosupplies.com/wp-content/uploads/2017/11/Solderless-Breadboard-400-Hobby-Line-2.jpg

Verification

UNVERIFIED against a photo of the actual owned units — this entry was created from a direct count Alex gave in chat ("4 breadboards, 2 full, 2 half") rather than the original photo intake workflow. Quantity (2) is high-confidence since Alex stated it directly; physical details (tie-point count, exact column count, brand) are typical-for-class assumptions only. Replace the representative photo and confirm specs once an actual photo of these units is available.

Notes / gotchas

• This entry deviates from the normal intake workflow (no photo of the actual part) — treat the “Key specs” section as a reasonable placeholder, not confirmed fact, until a real photo comes in.
• Distinct from the full-size breadboard — half the tie points, one terminal-strip block instead of two.
