SRA Board
The SRA board is a development board based on ESP32 with on-board peripherals like a programmable LED matrix, switches, sensor ports for Line Sensor Array and MPU-6050, protection circuit for over-current and reverse voltage, and motor drivers.
About the Project
- This development board is used for the Wall-E and MARIO workshops conducted by SRA.
- Designed using KiCAD.
Getting Started with a Development Board
In general, every development board has the following basic features:
-
Power Supply Unit
- Microcontrollers (MCUs) usually run on 3.3V or 5V logic supply voltage while input to a development board is normally 12V for motor and driving/controlling peripheral devices.
- So, in order to have a single input source, a power section which inter converts this 12V to standard levels like 5V & 3.3V for MCU and sensors is present.This is achieved using a step-down buck regulator.
