Hi everyone,
I have available for sell one Yardstick One dongle + 433Mhz antena. For those not familiar with the item, it is RF board based on texas cc1111 that can transmit or receive digital wireless signals at frequencies below 1 GHz.
The item is in like new condition, bought it for a few experiments and it served its purpose but now is resting in a drawer for some time.
