The backside of the plate houses all of the other components; solder terminal for the batteries, a TP4056 which manages the aforementioned batteries, a Qi Wireless charger receiver, a load cell balancer and last but not least an ESP32.
The ESP32 is a powerful little microcontroller with built in features such as wake up on touch and Bluetooth Low Energy.
This component acts like the brain of our Plåtta.
Our project was time boxed in 10 weeks so we had to move fast.
Our multidisciplinary team unfortunately did not have anyone who was experienced with building PCBs. But we got advice from the expert at the Havenlab.
We used Eagle to design our PCB and the design rule files Eurocircuits provide for this program, made the process a lot easier.
The short factory time at Eurocircuits helped us to us successfully finishing off our first prototype just in time for the presentations.
For assembly the RDM: Centre of expertise in Rotterdam supplied us with tools and an expert dedicated to give advice on our project.
Since this is our first time making our own PCBs we made quite some mistakes during the assembly.
Thanks to Eurocircuits
With Eurocircuits we had the confidence that we could replace multiple components without tearing any traces or loosening any pads.
We would like to thank Eurocircuits and the experts at the RDM: Centre of Expertise for their time and their support!
Without them it simply wouldn’t have been possible to make our ambitious project a reality.
