Hex Wrench 3/32"

3/32" Long Arm (3") Hex Wrench for fingertech switch

Interface Cable - SMA 9.8in

This is a basic SMA (Sub-Miniature A) male to female connector cable. Each cable is 25cm (9.8in.) long with RG174 housing. The SMA connectors at each end are small enough for most consumer GPS, cellular, and other RF applications and they use a threaded housing to create strong mechanical connections. These work well for mounting an antenna to the outside of an enclosure, while keeping the electronics neatly inside.

LipoCharger

LipoCharger is designed to take power from a micro USB connector and charge a single-cell LiPo battery. There are five switchable charge rates, from 100 to 500mA.
