SPEBlox (1GBASE-T1) - Tiny Single Pair Ethernet Converter

The SPEBlox (1GBASE‑T1) is a groundbreaking single‑pair Ethernet converter that seamlessly bridges standard gigabit Ethernet (1000BASE‑T) with single‑pair Ethernet (1000BASE‑T1). It comes in a remarkably small 30 mm × 30 mm × 11 mm form factor, making it perfect for space‑ and weight‑constrained applications like drones, robotics, and embedded systems. It functions as a transparent plug‑and‑play bridge—8‑wire RJ‑45 Ethernet in and 2‑wire screw‑terminal SPE out—with no software configuration required. One device acts as master, the other as slave, selected via a simple jumper setting. Powered from 5–40 V with up to 65 V transient tolerance, it consumes around 1.4 W at full gigabit rate. Though primarily data‑only, it supports full 1 Gbps over single‑pair Ethernet across typical cable lengths of up to approximately 22 m on 28 AWG twisted pair. It’s designed to simplify cabling—reducing wire count by a factor of four—without sacrificing bandwidth. SPEBlox is ideal for proof‑of‑concept evaluation and system integration. For higher-volume or embedded use, BotBlox offers a PCB‑mountable SPEBlox Module (castellated, NDAA-compliant) slated for availability mid‑2025. Key specifications: * Gigabit speed (1000BASE‑T to 1000BASE‑T1) * Dimensions: 30 × 30 × 11 mm; weight \~10 g * Power: 5–40 V input, \~1.4 W consumption * Cable range: \~22 m at 1 Gbps * Passive, firmware‑free operation via master/slave jumper In summary, SPEBlox packs full gigabit performance into a tiny, rugged converter that cuts cabling hassle while enabling modern single‑pair Ethernet designs.
