Description
The Rack32 is a control board that helps you build your own rack-mounted projects for home automation, industrial automation, music, networking, or anything else that can take advantage of standard 19″ rack hardware.
It is one component of the Universal Rack Controller project, which provides you with a framework for building your own rack-mount devices.
The Rack32 comes in two versions. The regular “RACK32” version includes an onboard PCB antenna, which is convenient if you don’t care about WiFi performance and will connect to it via Ethernet or USB. The “RACK32E” version has a U.FL socket for an external WiFi antenna, which will allow you to have excellent WiFi performance even if your project is mounted inside a metal rack-mount enclosure.
If you select the “RACK32E” version, you can pair it with the 2.4GHz / 5GHz Antenna with Lead for maximum performance even inside a metal enclosure.
