Assembled Node

The smallest production IRLP node

IRLP - Keeping the Radio in Amateur Radio

The PiRLP4 measures just 4" x 2.5" x 1.5", making it the most compact production IRLP system. It contains all the same components as other PC-based and Pi-based IRLP nodes, just more compact. The IRLP version 3.0 board and USB sound card are modified and secured within the confines of the small ABS plastic case. The system has integrated 802.11AC WiFi and BlueTooth 5.0 included.

All of the 6 indicators are viewable from outside the case. The COS, PTT, and DTMF indicators are labelled.

The case can be easily opened to access the IRLP board jumpers.
