Specs
- 2700K
- About 400 lumens
- Dimmable
- Rechargeable
- Flashes when battery low
Implementation
- Micro: RP2040
- LED Driver: TPS61165
- LED: OSRAM GW JTLPS1.EM-KKLL-XX58-1
- Batteries: TBD
- Battery charger: TBD
TODOs for V1 order:
- Check order of LEDs
- Check the caps footprint
- C15, C16 are wrong size
- Remove todo from schematic
TODOs for v2:
- Add charging status to micro
- fix the led circuit switching
- enable low power mode with reset switch (no long press. How did we switch all circuits on mopi?)
- Remove the cap on qspi_ss
- DNP for the 3.3V led
- Add a buck boost instead of ldo -> Remain with LDO but remove shotky diode (need to add it in case?)
- Check the bat sense feature - probs ok
- White circuit for reflection - will do
- Add gnd, vref, 3.3V to the debug port
- Add the 10k resistor to the TS pin on the charger -> changed charger and fixed TS
- Switch to ULDO
- Change the battery holder -> changed to double battery holder
Nice to have:
- i2c connected charger
- Protrude the button more
- Nice feeling button
TODOs for V3
- add a label for +/- battery
- remove the pullup on the on/off bt
- add a blinky led

Questions
How big is the Inflatable led PCB?
It measures 91.8 × 92 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Inflatable led use?
106 parts, built around the RP2040, TPS61165DRVR, W25Q128JVSIQ TR and 74LVC1G32SE-7-76. 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 Inflatable led KiCad files?
From the Timot05/inflatable_led repository on GitHub, at the commit this page was made from: the board is elec/inflatable_led/inflatable_led.kicad_pcb and its schematic elec/inflatable_led/inflatable_led.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Inflatable led design in my own project?
Its repository states no licence, so its author keeps all rights: ask Timot05 before reusing the design.
