YARD Stick One (Yet Another Radio Dongle) can transmit or receive digital wireless signals at frequencies below 1 GHz. It uses the same radio circuit as the popular IM-Me. The radio functions that are possible by customizing IM-Me firmware are now at your fingertips when you attach YARD Stick One to a computer via USB.

FEATURES
YARD Stick One comes with firmware installed, courtesy of . RfCat allows you to control the wireless transceiver from an interactive Python shell or your own program running on your computer. YARD Stick One also has installed, so you can upgrade RFCat or install your own firmware without any additional programming hardware. The ANT500 antenna is included.
Originally based on the design, YARD Stick One has several featured not previously seen in CC1111 platforms:
- SMA connector for external antennas such as
- receive amplifier for improved sensitivity
- transmit amplifier for higher output power
- strong RF performance across the entire operating frequency range
- low pass filter for elimination of harmonics when operating in the 800 and 900 MHz bands
- antenna port power control for compatibility with antenna port accessories designed for
- -compatible expansion and programming header
- -compatible programming test points
