Part Review and Datasheet Update

flux

Completed the part review and set the official Espressif Datasheet URL on the part. I created the full review here: ESP32-C3-DEVKITM-1 Part Review.
Open items:
  • J3 pin numbering/orientation should be confirmed against the footprint geometry before publishing.
  • Pin descriptions are sparse and should be expanded with official GPIO/ADC/UART/USB/strapping functions.
  • Package/mechanical metadata is missing or too generic.
Suggested next steps:
  1. Update terminal Pin Description properties from the official Espressif pin table.
  2. Verify and, if needed, correct J3 footprint pad numbering.
  3. Add explicit package/mechanical metadata for the 2x15 header dev-board footprint.

Fix the pin descriptions, verify J3 numbering, and add the missing package metadata.

flux

I’ll update the terminal descriptions and package metadata, then inspect the footprint/pad ordering to verify whether J3 is intentionally reversed or needs correction.

flux

Pin descriptions are updated from the official Espressif J1/J3 header table. I’m adding the package metadata and then I’ll verify the final mapping.

flux

Completed the fixes: all 30 terminals now have official Espressif pin descriptions, package/mechanical metadata was added, and J3 numbering was verified as reversed physical order: Flux pins 16–30 map to J3-15 through J3-1.
Updated report: ESP32-C3-DEVKITM-1 Part Review.
Open items:
  • None from the requested fixes.
Suggested next steps:
  1. Run the part review checks to confirm metadata/terminal warnings are cleared.
  2. Publish or republish the corrected part if this is intended for reuse.

Key Specs
  • Core device: ESP32-C3-MINI-1 module on ESP32-C3-DevKitM-1 development board
  • Flash: 4 MB flash
  • Wireless: 2.4 GHz Wi-Fi 802.11 b/g/n and Bluetooth Low Energy
  • Processor: 32-bit RISC-V single core, up to 160 MHz
  • External headers: Two 15-pin header rows, J1 and J3, represented in Flux as a flattened 30-pin terminal set
  • Power pins: 3V3 pins on J1-2/J1-3, 5V pins on J1-13/J1-14, multiple GND pins
  • USB pins exposed: IO18 = USB_D−, IO19 = USB_D+
  • UART pins exposed: TX = GPIO21/U0TXD, RX = GPIO20/U0RXD
  • Special notes: GPIO2, GPIO8, and GPIO9 are strapping pins. GPIO8 also drives the on-board RGB LED.
Verified Pin Numbering
Pins 1–15 match Espressif header J1 pins 1–15 directly.
Pins 16–30 represent J3 in reverse physical order. This is consistent with the existing footprint/symbol mapping and the signal set:

Corrective Changes Made
  • Added official Pin Description properties to all 30 terminals.
  • Confirmed the J3 side is intentionally reversed in Flux pin numbering: Flux 16 → J3-15 through Flux 30 → J3-1.
  • Corrected the ambiguous J3 GND descriptions at Flux pins 16 and 30.
  • Added missing package/mechanical metadata at project level.
Remaining Notes
  • The package metadata uses non-standard project-level property names because this is a published part project and the standard project property list does not include all component package fields.
  • The layout inspection confirms 30 pad nodes and an ESP32-C3-DevKitM-style footprint outline, but did not expose detailed pad coordinates in the tree response. The J3 numbering conclusion is based on the existing terminal pin numbers and official signal order.
