4LDR Board is an open source PCB design by CarlosGS, published on GitHub. It is a 2-layer board measuring 20.3 × 21.6 mm, with 5 components from 5 distinct parts.

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

From the project

A 3D-printable robotic platform for testing swarm algorithms

An efficient solution for powering mobile robots. The GNBoard can also incorporate a ZigBee-compatible module and many other multimodal sensors (a gas detector for odor sensing, an accelerometer/electronic compass, temperature and humidity sensors, luminosity sensors), and multiple kinds of actuators as well (servomotors, a speaker, LEDs, etc).

The motion of the robot is achieved using two continuous rotation servomotors (SM-S4303R) as the main actuators. Servomotors provide a compact and low-cost solution to achieve the digital speed control needed. The main downside of this kind of…
