About the SPEED GOVERNOR TRIAL 2 PCB

SPEED GOVERNOR TRIAL 2 is an open source PCB design by KaburaJ, published on GitHub. It is a 2-layer board measuring 34.3 × 23.6 mm, with 10 components from 7 distinct parts.

Other key parts include the L7805, RFM69HW and HT12E. By type, the board carries 4 switches, 3 ICs, 2 connectors and 1 resistor.

It belongs with the rf & radio and displays & leds designs in this gallery.

From the project

This repository contains the workflow of a dynamic speed governor. Designed to change as per a location's speed limit, this dynamic speed governor is highly applicable in school zones, hospitals and black spots among others.

This is a small PCB sub-assembly capable of transmitting and modulating a radio wave to carry data.

Converts parallel inputs into serial output. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. These 12 bit are divided into 8 address bit and 4 data bits.

It is a simple switch mechanism to control the speed limits aspects of the project. The comprise of the 20, 40, 60 and 80 km/hr speed limits.
