Mx5-light
About the Mx5-light PCB
Mx5-light is an open source PCB design by rodriveiga01, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 100 × 70 mm, with 39 components from 14 distinct parts.
By type, the board carries 8 test points, 5 diodes, 4 transistors, 4 relays, 4 resistors and 3 connectors.

- ERC: 0 errors. DRC: 22 unconnected GND items because CLI checks do not fill zones. - Library remapping is required. Relay footprints are placeholders and must be corrected. - Connector fit, motor current, relay rating, and relay polarity remain unverified. - Do not order a board until layout checks and bench validation HV1–HV4 pass.
