_Notes:_ Verified BusPirate5-hardware repo tree via gh api (recursive): bus_pirate_pcb/5-REV10A/REV10a.kicad_pro/.kicad_pcb/.kicad_sch plus sub-sheets exist alongside enclosure/BusPirate5REV10-v0.stl; both GitHub blob links and the docs.buspirate.com schematic PDF returned HTTP 200. Repo is MIT-licensed and also contains many other BP5 adapter boards (fully open). RP2040 datasheet URL 301-redirects to pip.raspberrypi.com but resolves successfully. The interactive BOM HTML and the 5-REV10A tree URL were also checked (200). The display driver IC is not named on the introduction page (only '320 x 240 pixel IPS'); check the KiCad schematic for it.

## Specifications

### Bus Pirate 5 revision 10

| | |
|---|---|
| Processor and flash | RP2040; 128 Mbit (16 MB) firmware flash. |
| Buffered I/O | Eight tri-state pins; stated operating range 1.65–5 V. |
| Pin tools | Voltage measurement per pin and switchable 10 kΩ pull-ups. |
| Connectors | 10-pin 2.54 mm main header; 9-pin 1 mm auxiliary header. |
| Storage | 1 Gbit (128 MB) NAND exposed as USB storage for settings/files. |
| Status display | 320 × 240 IPS; pin labels, voltages and supply current. |
| Controls | One button and 18 RGB LEDs. |
| USB | USB-C; data speed is limited by RP2040 hardware. |

### Target wiring and power

| | |
|---|---|
| Target supply | 1–5 V output; rated maximum 300 mA. |
| Protection setting | 0–500 mA current-limit range; extra headroom is for transients, not a 500 mA output rating. |
| Supply behavior | Disabled in HiZ mode; current-limit trips shut the supply off. |
| Main-header map | Pin 1: VOUT/VREF; pins 2–9: IO0–IO7; pin 10: target ground. |
| External reference | VOUT/VREF can accept a target reference to power the I/O buffers. |
| Accessory requirement | Probe and auxiliary cable kits are separate listed products; verify the purchased bundle. |
| Firmware-controlled pins | Protocol functions vary by mode; use the displayed pin labels and official pin map. |

### Setup and model boundaries

| | |
|---|---|
| Terminal | Use a serial terminal; quickstart specifies 115200 baud, 8-N-1 and VT100. |
| Two serial ports | One is the terminal and one is binary access; numbering is not guaranteed. |
| Platforms | Official quickstart provides Windows, Linux and macOS terminal paths. |
| Protocol reference | SPI, I²C, UART and other modes have separate commands and limits. |
| Revision-specific image | Production rev10 uses bus_pirate5_rev10.uf2; rev8 engineering samples use their own image. |
| Bootloader | RP2040 hardware bootloader exposes RPI-RP2 for UF2 updates; recovery instructions are linked. |
| Newer boards | Bus Pirate 6 uses a different RP2350 image; match board/revision before flashing. |
| Design files | Rev10 hardware documentation links schematics, component placement and an interactive BOM. |
| Firmware channel | Official downloads are automated builds from main; review the build and revision before updating. |
