New product: Radio module 450MHz
Today we are launching a new radio module compatible with the unlicensed 450 MHz spectrum. The new Radio module 450MHz allows you to connect ArduSimple products with high-end devices that support the TRIMTALK radio protocol to allow seamless cross-brand operations in the field.
To use this radio module, you will need a 450 MHz dipole antenna.
What is TRIMTALK? TRIMTALK is a proprietary UHF radio protocol developed by Trimble Inc. It is used to transmit real-time kinematic RTK corrections between RTK base and rover.
