Concerns
- Power
- 12V deep cycle marine batteries
- Charging circuit
- Solar array
- Delivering 12V to each tree (voltage drop)
- Firmware
- Performance over time
- Running 4x trunks vs 1 trunk 4 times
- Lighting
- Soldering high current LEDs
- 144/m 5m vs splicing power

Questions
How big is the TeensyShield progLED PCB?
It measures 110 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TeensyShield progLED use?
85 parts, built around the MCP1700T-3302E/TT(MS) and SN74LVC8T245PWRE4. 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 TeensyShield progLED KiCad files?
From the samuelclay/grove repository on GitHub, at the commit this page was made from: the board is main board/teensyShield_progLED.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TeensyShield progLED design in my own project?
Its repository states no licence, so its author keeps all rights: ask samuelclay before reusing the design.
