1 × Lepton 3.5 Breakout board https://store.groupgets.com/collections/flir-lepton-accessories/products/flir-lepton-breakout-board
1 × Teensy 3.2 https://www.pjrc.com/store/teensy32.html
2 × 4.7 kohm resistor I2C pull-ups
2 × 35.7 kohm resistor part of voltage divider. Different values can be used. See the project log describing the hardware.
2 × 11.5 kohm resistor part of voltage divider. Different values can be used. See the project log describing the hardware.
1 × 2 kohm resistor pull-down for MOSFET. Not critical. A 10 kohm resistor would be fine.
2 × 0.1 uF ceramic cap
1 × 100 uF, 16v electrolytic cap
1 × 3.7 volt LiPo battery around 1000 mAh I used a battery from an old cell phone that I soldered a mating JST cable onto to connect to the charger.
1 × misc hookup wire, etc.
1 × ILI9341-based LCD Shield (LinkSprite LCD Touch) http://store.linksprite.com/2-8-touch-lcd-shield-for-arduino-pcduino/
1 × Arduino proto shield (Freetronics model) https://www.freetronics.com.au/products/protoshield-basic
1 × Teensy to Arduino breakout (Sparkfun) https://www.sparkfun.com/products/13288
1 × LiPo charger/5V Boost converter I used the Sparkfun PowerCell but it seems to be retired now. I think the newer device could be adapted: https://www.sparkfun.com/products/14411
1 × 3-way navigation switch I used the Sparkfun device but it seems retired now. This can be replaced by three separate buttons. https://www.sparkfun.com/products/retired/8236
1 × SPST Button Any momentary contact button can be used for the power button
1 × Logic-level N-channel MOSFET I used an IRLML2803 because I had it laying around. Important characteristics are low Vgs and relatively low Rdson.
1 × BAT54 schottky diode Any low Vf diode will work (the one I used has about 0.3V Vf).
