Manufacturer manuals, schematics and pinout gaps
Collection 2026.10.4 expands Waveshare, M5Stack and NodeMCU documentation while keeping the limits of each source clear.
C5 boards, new references and project support
Waveshare C5 pinouts, M5Stack and NodeMCU reference updates, and the optional Patreon link.
New vendor pin and schematic references
Find the October additions from Seeed, M5Stack, Waveshare, Arduino, Adafruit, DFRobot and Renesas.
High Boy V2_03 schematic
The eight-page schematic dated September 29, 2026, with the older MVP revision kept separate.
Install and update the desktop app
One installer, a persistent offline library and updates inside Black Wire.
Zoom and pan a reference
Pinch, drag and use keyboard controls on original images and PDF pages.
LoRa radios and GPIO devices
Match the radio module, carrier, region and board revision before using a connector reference.
HaleHound and Elechouse hardware references
Find CYD assembly diagrams, exact NFC module variants and original connector documentation.
Inland and manufacturer coverage
Match Inland SKUs and DFRobot variants, inspect the original diagrams and see what remains missing.
New hardware and source checks
Find ESP-Mosaico, P4X boards and FPGA references while keeping availability, revisions and unresolved evidence visible.
Datasheets, I/O boards and carrier revisions
Find the original device documentation and understand which connector a reference actually covers.
ARM, x86 and RISC-V computers
Find SBC references by architecture, manufacturer and exact model, including LattePanda and Milk-V.
Start at the workbench
Find the exact board, open a useful pinout and keep its source and revision close.
How to read a pinout reference
Distinguish physical connector positions, GPIO names and alternate functions before wiring.
GPIO, I²C, SPI and UART
A quick introduction to the signal names you will meet in maker pinout sheets.
Identify displays and sensors
Use controller, interface, board revision and physical connectors to distinguish similar modules.
Use the Power Desk carefully
Read supply requirements, compare adapter labels and estimate battery runtime without confusing a calculation with a hardware test.
Find a power-module reference
Distinguish buck, boost, buck-boost, charger and protection records before selecting a pinout.
Search, themes and saved boards
Use keyboard search, scope filters, dark or light mode, original downloads and workbench backups.
Coverage, sources and review status
What each coverage label means and where the remaining documentation gaps are recorded.
Help improve the maker reference
Report errors, contribute sources and request hardware with enough evidence to review.
