The Smallest Network Switch mrxSwitch v2.0 Created by MurexRobotics

TapTechNews reported on June 18 that the MurexRobotics underwater robot team of Phillips Exeter Academy (PEA) has created the so-called world's smallest network switch, the mrxSwitch v2.0, and the price is much lower than similar products.

The mrxSwitch v2.0 is specifically designed for remotely operated underwater detectors and can provide five 100 Mbps Ethernet ports, with an area of only 1.77 inches x 1.66 inches.

The team designed the network switch mainly for remotely operated underwater vehicles (ROV) or autonomous underwater vehicles (AUV), but the team also stated that the switch is suitable for various embedded devices.

In the case shared by the MurexRobotics team, this switch is applicable for communication between a Raspberry Pi, NUC or other computers and IP cameras, drive motors or other tools to operate the underwater robot.

The switch is equipped with 5 beige 4-Pin ports, using MolexPicoBlade connection, which saves more space than RJ-45 ports. The integrated chip responsible for switching on the board is smaller than a fingernail, and the largest component is a dual-port transformer, with a length just a little longer than a knuckle. Compared to the previous-generation product, the mrxSwitch v2.0 has reduced its volume by 30% and the BOM cost by 15%, and the current material cost is $7 (TapTechNews note: about 51 yuan currently).
