Example boards plan

[ducky64]

TODO

• change BLE joystick to use basic part linear regulator - XC6206P332

• Also AMS1117-33/-5.0 for beefier power - keyboard example

• BLE joystick tri-level board as tech demonstrator for multi-board composition functionality

  • nRF52 series MCU
  • CH32V003 IO expander in TSSOP20

• fan driver / npx driver combo board with segmented onboard LED ring and encoder

  • replaces the iot knob example
  • likely also a multi-board composition demonstrator
  • ESP32-C6 for 802.15.4 comaptibility
  • reverse input protection pmos
  • high side switch, dfn6x6 pmos
  • INA219
  • VL53L8, maybe
  • speaker w/ RC "DAC"
  • optional USB-C or barrel jack combination
  • qwiic expansion

• basic mechanical keyboard

  • 3x4 macropad
  • refactor to SwitchCell for hierarchical layout replication, with WithNeopixel mixin
  • rotary encoder, top right
  • 128x32 OLED, top middle
  • USB-C, top left
  • CH32V203 series in QFP32

• poe ethernet thermal camera

  • PoE and ethernet demonstrator
  • W5500 ethernet IC
  • Probably nonisolated PoE using TPS2378 + LMR38020; not allowed to use PoE + USB simultaneously
  • Future: flyback generator using integrated TPS23753

Future:

• strain gauge board
• obd spin
  • LTE connectivity

Lower priority:

• Mechanical keyboard with bidi USB-C
• BLDC refresh
• seven-segment spin
• high-power led driver spin
• 18650 power bank
  • possibly bq25792 for power path
  • or MP2651, though limited to fixed 5v OTG
