Overview

Starbie is an open-source printed circuit board by Cryptoblade9623, from the Cryptoblade9623/Starbie repository on GitHub. It is a 2-layer board of 85.6 × 98.8 mm with 21 parts on 25 nets, routed with 51 tracks and 12 vias.

It is built around the DHT11. Its parts include 2 ICs, 2 connectors, 2 switches and 1 resistor. It belongs with the lEDs and displays boards and the ESP32 and RISC-V boards of this library.

Starbie

Motion and button controlled pet with an OLED display, humidity and temperature sensor and motion sensor. It is controlled by an ESP32 C3 Supermini. This is a guide, by SharKing Studios from Half-Life. The files include the KiCad files, gerbers, drill files, firmware - which you will have to put into a folder of the same name and then open in the Arduino IDE, footprints for the custom silkscreen, non - KiCad symbols and footprints for the screen, ESP32, and DHT11, and my personal sprite creation. I have not included the swicthes and keycaps because I have 4 switches and quite a few keycaps from previous projects.

Instructions

  1. Solder the 10K ohm resistor onto the top left corner of the board.
  2. Solder the MPU6050 onto the middle area of the board with pinheaders.
  3. Solder the mechanical switches into their corners on the PCB.
  4. Solder on the OLED display in the middle of the board, above the MPU6050.
  5. Solder the DHT11 in between the resistor and the OLED.
  6. Finally solder the ESP32 onto the right side of the board so that the USBC port just hangs off the egde.
  7. You can also add some small stickers onto the tips of the corners or on the back if you have them, but this is completely optional. And you're done!

Questions

How big is the Starbie PCB?

It measures 85.6 × 98.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Starbie use?

21 parts, built around the DHT11. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Starbie KiCad files?

From the Cryptoblade9623/Starbie repository on GitHub, at the commit this page was made from: the board is Files/KiCad/Starbie.kicad_pcb and its schematic Files/KiCad/Starbie.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Starbie design in my own project?

Its repository states no licence, so its author keeps all rights: ask Cryptoblade9623 before reusing the design.
