Part Review and Datasheet Update
Thought for 6 sec
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.
Worked for 1 min 1 sec
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.
Worked for 1 min 53 sec
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:
- Run the part review checks to confirm metadata/terminal warnings are cleared.
- 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:
Table
| Flux pin | Signal | Official header pin/function |
|---|---|---|
| 16 | GND | J3-15: Ground |
| 17 | IO19 | J3-14: GPIO19, USB_D+ |
| 18 | IO18 | J3-13: GPIO18, USB_D− |
| 19 | GND | J3-12: Ground |
| 20 | IO4 | J3-11: GPIO4, ADC1_CH4, FSPIHD, MTMS |
| 21 | IO5 | J3-10: GPIO5, ADC2_CH0, FSPIWP, MTDI |
| 22 | IO6 | J3-9: GPIO6, FSPICLK, MTCK |
| 23 | IO7 | J3-8: GPIO7, FSPID, MTDO |
| 24 | GND | J3-7: Ground |
| 25 | IO8 | J3-6: GPIO8, RGB LED; strapping pin |
| 26 | IO9 | J3-5: GPIO9; strapping pin |
| 27 | GND | J3-4: Ground |
| 28 | RX | J3-3: GPIO20, U0RXD |
| 29 | TX | J3-2: GPIO21, U0TXD |
| 30 | GND | J3-1: Ground |
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.
