Hardware fact sources (provenance)

All hardware facts used by the dataset live in configs/rpi5_hardware_facts.json. Every fact has an ID (F-...) and cites one of the sources below by source_id plus a section, table or page locator. Facts are paraphrased and quote no long passages. Re-verify them against the live documents before changing them.

Retrieved with Firecrawl on 2026-09-13.

RP1_PERIPH Raspberry Pi RP1 Peripherals datasheet RP-008370-DS-1, build-date 2023-11-07, build-version b9b6f74-clean https://datasheets.raspberrypi.com/rp1/rp1-peripherals.pdf

GPIOZERO_DATA GPIO Zero pin data (the library the official docs use for the pinout command, installed by default in Raspberry Pi OS) gpiozero/pins/data.py on master, PI5_J8 = PI4_J8 https://raw.githubusercontent.com/gpiozero/gpiozero/master/gpiozero/pins/data.py

GPIO Zero notes that its Pi 5 alternate-function data is inherited from the Pi 4 and "slightly wrong". The dataset therefore takes only the physical header layout from GPIO Zero and takes every alternate function from RP1 Table 4. The header layout agrees with RPI_DOCS_HW (GPIO0/GPIO1 on physical pins 27/28, two 5 V and two 3.3 V pins).

Locators used

  • RP1_PERIPH Ch.1 Introduction: RP1 provides 28 GPIO pins for the 40-pin header.
  • RP1_PERIPH §3.1 GPIO: one bank (IO_BANK0), function list; IO_BANK1/2 are reserved for internal use.
  • RP1_PERIPH §3.1.1 Table 4 "GPIO function selection": per-GPIO alternate functions a0–a8.
  • RP1_PERIPH §3.1.3 Pads: drive strength 2/4/8/12 mA, pull-up/pull-down/bus-keeper, fault tolerance below 3.63 V when unpowered.
  • RP1_PERIPH §3.1.4 PADS_BANK0 GPIOn register: DRIVE reset = 4 mA, PUE/PDE reset "varies", SCHMITT reset = enabled.
  • RP1_PERIPH §3.2 UART: six PL011 instances, five on bank 0.
  • RP1_PERIPH §3.4 PWM: four independent channels per PWM block.
  • RP1_PERIPH §3.5 I2C: DesignWare I2C, master by default, 7-bit addressing in master mode.
  • RP1_PERIPH §3.6 SPI instance table: SPI4 and SPI7 are slave-only; the rest are master.
  • RPI_DOCS_HW GPIO: 40-pin header; input, output, or up to six alternate functions; GPIO0/1 reserved for advanced use; output high 3.3 V / low 0 V; GPIO2/GPIO3 have fixed pull-ups; the hardware PWM list; SPI0/SPI1/I2C pin lists; warning not to connect motors directly and to use current-limiting resistors with LEDs; do not use 5 V for 3.3 V components; inputs are 3.3 V-tolerant.
  • RPI_DOCS_HW GPIO pads control: drive strength is not a current limit; a pad shorted while driven will eventually fail.
  • RPI_DOCS_HW Power supply: GPIO pins combined can safely draw 50 mA, 16 mA per pin (general statement, not Pi 5-specific: see human review).
  • RPI5_BRIEF Specification: Raspberry Pi standard 40-pin header; 5 V/5 A USB-C power; operating temperature 0–70 °C.

General English text is mixed in for language competence only. It is never a source of hardware facts: documents about Raspberry Pi, GPIO, Arduino, ESP32, pinouts and similar are filtered out (see configs/english_corpus.json).
