trianguloMTX-65ULP + MTXTunnel

Same features as the MTXTunnel-65i but it is designed for ULP applications (ultra-low power) where the device needs to be powered with batteries or solar panels. Consumption in ULP mode: 2.5uA

trianguloMTX-65+G + MTXTunnel

Its features are nearly identical to the MTXTunnel-65i but it has an internal module for GPS positioning.
