This #Badgelife PCB was created to test some circuits to be used in future art PCBs. I also wanted a small project to bring to local hardware meetups. Partial assembly done at jlc.
*missing front buttons on this test PCB
- Powered by x2 AA Batteries
- Highly compatible with JLCPCB's basic SMT parts
- Raspberry Pi RP2040 uC w/ Dual core ARM Cortex-M0+
- OLED Screen, RGB LEDs, Buttons
- SAO Connector!
I rushed this project a lot. Schematic was done in a few nights, layout and routing in a few hours with no review. This PCB has a few mistakes. Not planning on making another board spin but leaving this list here.
- I seen someone's design online using a RGB led running at 3.3V (below spec). I tried to replicate it and the LEDs were very flaky and worked intermittently. Experiment failed 😢.
- AA boost converter not yet tested, just using USB power so far.
- User led + pwr led
- ON OFF silk on switch
- Buzzer would be fun
- 5.1k USB cc1 cc2
- Planes on batt terminals to prevent lifting
- Use RPI boost for AA supply instead of boost converter ○ Its nice to have 5V for leds
- Sao is to big for this little thing.
- GND probe clip stuffing option
- lvl shifter for RGBs
