LoFi Walkie Talkie

File Organization as it pertains to Nick(our sage git master) 1) If a program creates multiple files, only push the ones ones that are needed for others to use the program (i.e. don't push things like log files) 2) If a program has multiple files, create a folder dedicated to them in the correct spot, ask if you're not sure what the spot is (i.e. if projectlibre has a project file and an image/pdf, create a folder in documentation called "Gantt Chart" 3) Do not keep previous revisions, git does that for us. You can tag the commit of the previous version if you feel inspired (i.e. don't have…

RF-Tin-Can: common questions

What microcontroller does the RF-Tin-Can use?

The RF-Tin-Can is built around the ATTINY85-20SUR, from the AVR/Arduino family.

How big is the RF-Tin-Can PCB?

The RF-Tin-Can measures 70 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RF-Tin-Can?

72 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the RF-Tin-Can design files?

From the ECE411-Fall2021-Group4/RF-Tin-Can repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RF-Tin-Can design in my own project?

Yes, under the terms of its GPL-3.0 license, which ECE411-Fall2021-Group4 chose for the repository.

Can I test firmware for the RF-Tin-Can without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
