YARD Stick One also has CC Bootloader installed, so you can upgrade RFCat or install your own firmware without any additional programming hardware. RfCat allows you to control the wireless transceiver from an interactive Python shell or your own program running on your computer. YARD Stick One comes with RfCat firmware installed, courtesy of atlas. Unofficial operating frequencies work in our experience.) (Official operating frequencies are guaranteed to work. Modulations: ASK, OOK, GFSK, 2-FSK, 4-FSK, MSK.It's even better if you are HAM licensed with a wide range of transmitting frequencies! Great for listening on RF emitters and transmitting on ISM bands (check your country's ISM frequencies before transmitting). 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.
It uses the same radio circuit as the popular IM-Me. The expected output with no clock detected is -> 0x51.YARD Stick One ( Yet Another Radio Dongle) from Great Scott Gadgets can transmit or receive digital wireless signals at frequencies below 1 GHz. The expected output with a clock detected is -> 0x01. To verify that a signal has been detected on CLKIN, use hackrf_debug –si5351c -n 0 -r. The switch to or from CLKIN only happens when a transmit or receive operation begins. HackRF One uses CLKIN instead of the internal crystal when a clock signal is detected on CLKIN. You may directly connect the CLKOUT port of one HackRF One to the CLKIN port of another HackRF One. Do not connect a clock signal at a frequency other than 10 MHz (unless you modify the firmware to support this). Do not exceed 3.3 V or drop below 0 V on this input. The CLKIN port on HackRF One is a high impedance input that expects a 0 V to 3 V square wave at 10 MHz. The signal is a 10 MHz square wave from 0 V to 3 V intended for a high impedance load. HackRF One produces a 10 MHz clock signal on CLKOUT. External Clock Interface (CLKIN and CLKOUT) It is better to use an external attenuator than to risk damage. However, a simple software or user error could enable the amplifier, resulting in permanent damage. In theory, HackRF One can safely accept up to 10 dBm with the front-end RX amplifier disabled. Exceeding -5 dBm can result in permanent damage! The maximum RX power of HackRF One is -5 dBm. You are responsible for using your HackRF One legally. HackRF One has not been tested for compliance with regulations governing transmission of radio signals. If you connect an external amplifier, you should also use an external bandpass filter for your operating frequency.īefore you transmit, know your laws. Overall, the output power is enough to perform over-the-air experiments at close range or to drive an external amplifier. The frequency range with best performance is 2150 MHz to 2750 MHz. Through most of the frequency range up to 4 GHz, the maximum TX power is between 0 and 10 dBm. HackRF One’s absolute maximum TX power varies by operating frequency:ġ MHz to 10 MHz: 5 dBm to 15 dBm, generally increasing as frequency increases (see this blog post)ġ0 MHz to 2150 MHz: 5 dBm to 15 dBm, generally decreasing as frequency increasesĢ750 MHz to 4000 MHz: 0 dBm to 5 dBm, decreasing as frequency increasesĤ000 MHz to 6000 MHz: -10 dBm to 0 dBm, generally decreasing as frequency increases RP-SMA connectors are most common on 2.4 GHz antennas and are popular on Wi-Fi equipment. If you connect an RP-SMA antenna to HackRF One, it will seem to connect snugly but won’t function at all because neither the male nor female side has a center pin. Some connectors that appear to be SMA are actually RP-SMA. This means that it can be used for other functions by custom firmware. The DFU button only invokes the bootloader during reset. While holding the DFU button, reset the HackRF One either by pressing and releasing the RESET button or by powering on the HackRF One.
To invoke DFU mode: Press and hold the DFU button. This bootloader makes it possible to unbrick a HackRF One with damaged firmware because the ROM cannot be overwritten.
Designed to enable test and development of modern and next generation radio technologies, HackRF One is an open source hardware platform that can be used as a USB peripheral or programmed for stand-alone operation. The DFU button invokes a USB DFU bootloader located in the microcontroller’s ROM. Great Scott Gadgets HackRF One from Great Scott Gadgets is a Software Defined Radio peripheral capable of transmission or reception of radio signals from 1 MHz to 6 GHz. This is a reboot that should result in a USB re-enumeration. The RESET button resets the microcontroller.
