README
README.mdchase-badge
Designed using KiCad.
I tried to follow datasheet recommendations and tried to base the design on application note schematics and PCB layouts of the active components.
First revision of the board in the repo is rev-8. Earlier revisions are not available in this repo.
Schematics contain notes and all components should have their datasheet in their details in KiCAD.
Kudos
- to @smcatala for reviewing the designs!
Connectors
- USB-C for power, charging and with bootloader programming.
- FPC 4-pin for add-on boards.
- Li-Po JST-SH 2-pin.
Used ICs
ATTINY85V-20SU
- Chosen over ATTINY85V-10SU so we may support bit-banged USB protocol for programming the badge only with a USB cable. datasheet.
TLC6C9512PWR shift register
Chosen for low power consumption and low parts count. datasheet.
TPS63000 buck-boost regulator
MCP73837-FCI_UN battery charge manager
Tested
- Programming ATtiny85 with Tiny AVR Programmer
- ATtiny85, TLC6C9512 and LEDs can work as expected when powered externally
- 3.3V or 5V is supported.
Untested
- Power regulator
- Battery charge manager
- XSIG1 external signal, for supporting a buzzer, microphone etc.
- USB bootloader and programming from USB cable.
TODO
- Test everything under "untested" above.
- Determine Li-Po battery size.

Questions
How big is the Chase PCB?
It measures 26 × 26 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chase use?
179 parts, built around the ATTINY85V-15M, TLC6C5912GQPWRQ1, TPS63000DRC and DMN61D9UDW. 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 Chase KiCad files?
From the krk/chase-badge repository on GitHub, at the commit this page was made from: the board is hardware/chase.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chase design in my own project?
Its repository states no licence, so its author keeps all rights: ask krk before reusing the design.
