About the Ecal PCB

Ecal is an open source PCB design by joshajohnson, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 30 × 30 mm, with 14 components from 11 distinct parts.

Other key parts include the LP5912 and PE42440. By type, the board carries 5 capacitors, 3 connectors, 2 ICs, 2 resistors, 1 fuse and 1 diode.

From the project

25MHz to 1.25GHz Vector Network Analyser

Design is feature complete, but not suitable for use. Due to hardware issues the error is unacceptably large, and as such I can not recommend assembling one of these.
