# New vendor pin and schematic references

Find the October additions from Seeed, M5Stack, Waveshare, Arduino, Adafruit, DFRobot and Renesas.

## Find the exact model

Search ToughC5, Chain MIC, Chain Switch, Chain RGB, PaperMono-Lite, StackChan Core, DinMeter v1.1, AI Pyramid-Pro, UNO Breakout Carrier or EK-RA8P1 v1. These ten new records join expanded references for 124 existing records. Variant names and source revisions remain separate.

[ToughC5](https://valleytech-black-wire-guide.pages.dev/?board=m5stack-toughc5) · [UNO Breakout Carrier](https://valleytech-black-wire-guide.pages.dev/?board=arduino-uno-breakout-carrier) · [EK-RA8P1 v1](https://valleytech-black-wire-guide.pages.dev/?board=renesas-ek-ra8p1-v1)

## Read the connector and its purpose

Selected XIAO edge contacts and M5Stack HY2.0, Hat2-Bus and Cardputer-Adv EXT connectors have searchable source-backed pin-purpose tables. They cover 159 external contacts; internal GPIO allocation tables are not presented as exposed terminals. Use the matching manufacturer image for physical orientation and check all voltage and configuration requirements.



## Keep reference types distinct

The 232 added references include 14 physical pinout images, 152 original PDFs, 13 pin-function sheets and 53 supporting label, GPIO or connector references. Arduino carrier pages distinguish 3.3 V MCU signals from 1.8 V MPU signals. Renesas manual pages retain jumper, switch and unpopulated-header notes. Source photos, block diagrams and schematics do not establish a complete physical pinout.



## Coverage and publication

Collection 2026.10.2 is within First Edition / 2026. This targeted pass is not a complete worldwide inventory. Failed downloads, exact-variant leads and electrical-review gaps remain recorded. Original artwork retains its own rights. Existing desktop installers retain their published catalogs; the expanded references are available in the browser guide and current source.
