Start of Winter class (in Jan 2021)
Welcome to the Engineering Interactive Electronics onto Printed Circuit Boards class!
Published by Pedro Lopes on Mar 29 2021


In this class we will engineer electronics onto Printed Circuit Boards (PCBs). We will focus on designing and laying out the circuit and PCB for our own custom-made I/O devices, such as wearable or haptic devices. In order for you to be successful in engineering a functional PCB we will: (1) review digital circuits and three microntrollers (ATMEGA, NRF, SAMD), (2) use KICAD to build circuit schematics, (3) learn how to wire analog/digital sensors or actuators to our microcontroller, including SPI and I2C protocols, (4) use KICAD to build PCB schematics, (5) actually manufacture our designs, (6) receive in our hands our PCBs from factory, (7) finally, learn how to debug our custom-made PCBs. See here for class website (soon).

Expected workload

In this class you will engineer your own PCB from the ground up, by: designing it, engineering it, send it off to manufacturing, debugging it and improving it.
