This post is written by my friend (and now colleague/intern :) ) [Michele], who worked on the test board. I assigned him this task as it’s the best way to learn about the boards and get up to speed with the project. It also seemed a great way to test the really interesting Exclave project from [bunnie], but -spoiler alert- we’ll have to wait for that.
After manufacturing the boards, we need to test them to make sure that the assembly house built them correctly. This is my first time designing a nail bed, however the task seems quite simple. I have to test the following:
- Short circuits
- Voltage levels from the various power supplies
- Current consumption
- Communication (RS485, I2C, SPI …)
- Other signals to and from the board
