About the PCB board

PCB board is an open source PCB design by steger123, published on GitHub. It is a 2-layer board measuring 177.8 × 115.6 mm, with 94 components from 59 distinct parts.

Other key parts include the ACS712_30A, ST, LM7803_TO220, ADS1115 and LM7805_TO220. By type, the board carries 23 connectors, 7 modules, 5 ICs, 4 diodes and 2 switches.

It belongs with the robotics & motion, rf & radio and sensors designs in this gallery.

From the project

This project is an Open Source initiative to make a fully autonomous robot for grass cutting. Later much bigger stuff.

Create a general, affordable, computational platform, which can be used for small & medium size robots.

The navivation can be: fully maunal, semi and full autonomouse. The mechanical side not restricted. As the project progressing and evolving You can learn more and more, and of course, have the designs and codes for free.
