• Seeed Studio Xiao nRF52840
  • Be extra careful with soldering battery leads!
  • Careful with brown-outs when voltage gets too low!
  • Sometimes, it doesn't boot up correctly and reset button needs to be pressed.
  • Adafruit nRF52 Bootloader with Enhanced OTA DFU
• CN3791 MPPT charging board
  • Xiao's charging circuit sucks and will cause brown-outs when powering through USB!
  • TP4056 also sucks.
• 6V solar panel
  • 5V is not enough!
  • It needs a direct sunlight. It doesn't seem to work at all when shaded.
  • One morning of sunlight fully charges the battery after one week without sunlight.
• 18650 battery
  • Or any other 3,7 V lithium battery. 5 Ah pouch from old tablet is now in use. It kept running for 3-4 weeks without sunlight!
  • What will happen in extreme (+50, -10 °C) temperatures? 🤔
    • In freezing tempretures, capacity gets a bit lower, does not charge past 90-95 %.
    • After a week of 40 °C heat wave, everything looks fine.
    • Hail storm (2 cm) and high winds were also ok.
