Adafruit YARD Stick One - Sub-1 GHz Wireless Test Tool

YARD Stick One is a versatile radio dongle designed to transmit or receive digital wireless signals below 1 GHz. It utilizes the same radio circuit as the popular IM-Me and connects via USB for seamless integration with your computer.

Specifications include half-duplex transmit and receive, official operating frequencies from 300-348 MHz, 391-464 MHz, and 782-928 MHz, with unofficial extensions. It supports modulations like ASK, OOK, GFSK, and others, offering data rates up to 500 kbps.

With the pre-installed RfCat firmware, you gain interactive control of the wireless transceiver right from a Python shell or your own programs. The CC Bootloader enables easy firmware upgrades without extra hardware.

Distinct features include an SMA connector for external antennas, a receive amplifier for improved sensitivity, and a transmit amplifier for higher output power. It maintains strong RF performance and employs low pass filters to eliminate harmonics. Perfectly suited for advanced functionalities, the YARD Stick One offers expansion and programming headers compatible with GoodFET and GIMME standards.
