Comments for manufacturing the kit with Seeed Studio

LoNet 808

  • LoNET 808 should come come with GPS and Phone antenna, does it?
  • Header connector pins should be attached, can it be?
  • LoNET 808 Power LED can be low power / skipped as it drains battery

Comments for manufacturing PCBs

  • PCBs to soldered
  • PCBs to be Eco / Recycled PCBs / wood PCB

Comments for sourcing batteries

  • Battery 3000 mA/h, type: 18650, ideally Panasonic and cheap
  • Can you make sure the batteries are 100% charged?
  • Solder wires to the batteries (15cm) with connector mounted

Comments for sourcing battery charger

  • We need to charge 110 devices over 11 events. If we can charge 6 batteries at the time: great.

Ask about

  • Availabilites?
  • Timeline?
  • Bulk pricing?
  • Overall budget?
