## Blueprint

**Open hardware.** HackRF One's full KiCad schematic/PCB, laser-cut acrylic case files, and firmware are published under CERN-OHL-P (hardware) / GPLv2 (firmware).

### Source repositories

- [greatscottgadgets/hackrf](https://github.com/greatscottgadgets/hackrf) — hardware, GPL-2.0, ★8128

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| NXP LPC4320FBD144 | MCU (dual-core Cortex-M4/M0) | https://www.nxp.com/part/LPC4320FBD144 |
| Analog Devices/Maxim MAX2837 | 2.3-2.7GHz zero-IF RF transceiver |  |
| Analog Devices/Maxim MAX5864 | dual 8-bit ADC / dual 10-bit DAC (baseband AFE) |  |
| Qorvo RFFC5072 | wideband mixer + fractional-N synthesizer (frequency conversion) |  |
| Xilinx (AMD) XC2C64A | CPLD (glue logic) |  |

_Notes:_ Repo confirmed via gh api (GPL-2.0, 8128 stars); hardware/hackrf-one subfolder carries its own CERN-OHL-P-2.0 LICENSE (fetched). Chip part numbers confirmed by grepping raw mcu.kicad_sch/frontend.kicad_sch/baseband.kicad_sch for lib_id references (LPC4320FBD144, RFFC5072, MAX2837, MAX5864, XC2C64A). analog.com and qorvo.com blocked automated fetch (TLS/bot-protection, 000/429) in this environment so no direct manufacturer datasheet URL could be verified for MAX2837/MAX5864/RFFC5072/XC2C64A; NXP page for the MCU verified 200.

## Specifications

### RF and input limits

| | |
|---|---|
| Range | 1 MHz–6 GHz; half-duplex transmit or receive. |
| Samples | 2–20 MS/s; 8-bit I and 8-bit Q. |
| RF input maximum | −5 dBm; exceeding this can permanently damage the receiver. |
| Attenuation | Use external attenuation for stronger signals; disabling the RX amplifier is not reliable protection. |
| Transmit power | Frequency-dependent; no single output-power value covers the whole tuning range. |
| RF controls | Software-controlled RX/TX gain and baseband filtering. |
| Low sample rates | Documentation recommends ≥8 MS/s acquisition, then filtered decimation for narrower streams. |

### Connections and accessories

| | |
|---|---|
| Antenna port | 50 Ω SMA female. |
| Connector fit | SMA and RP-SMA may screw together without a working center contact. |
| Antenna power | Switchable 3.0–3.3 V, 50 mA maximum. |
| Clock ports | 10 MHz, 3.3 V square wave; CLKIN must remain between 0 and 3.3 V. |
| Host power | Supply 5 V at 500 mA through USB. |
| USB port | Micro-B connector with high-speed USB data. |
| Included | Enclosed HackRF One and micro-USB cable; antenna is separate. |
| Expansion | Internal headers and programming buttons; custom standalone operation requires appropriate firmware. |

### Software and revisions

| | |
|---|---|
| Host throughput | High-speed USB and sufficient CPU; shared USB traffic can restrict higher sample rates. |
| Install | libhackrf and HackRF Tools; official guide covers Linux, macOS, FreeBSD and Windows. |
| Windows path | Official guide points to radioconda binaries. |
| Version matching | Firmware may need updating to match host tools. |
| Firmware image | Use hackrf_one_usb.bin for SPI flash; model-specific .dfu is for recovery. |
| Revision identification | PCB silkscreen identifies revision; r6 onward also reports it through hackrf_info. |
| Revision differences | r9 changed RF/clock components; r10 largely returned to r8 design. Maker states common factory performance specifications. |
| Design and downloads | Firmware releases, host source and hardware designs are published by Great Scott Gadgets. |
