## Pinout
We don't publish a pin table for this part: no official source we could verify gives one. Check the labels printed on your module, and see the notes below.

## Common mistakes

- Holding GPIO2, GPIO8 or GPIO9 at the wrong level during reset: these pins select the chip boot mode ([source](https://www.espressif.com/sites/default/files/documentation/esp32-c3_datasheet_en.pdf))
- Raising VDD3P3_CPU above 3.3 V while writing eFuses: the eFuse circuits are sensitive to higher voltages ([source](https://www.espressif.com/sites/default/files/documentation/esp32-c3_datasheet_en.pdf))
- Running the chip supply above 3.6 V: the recommended input range is 3.0 V to 3.6 V ([source](https://www.espressif.com/sites/default/files/documentation/esp32-c3_datasheet_en.pdf))

## What we could not confirm

- Board is not an Espressif product: the HW-466AB pin layout, 5V pin, USB-C connector and board dimensions have no official source and are omitted.
- Flash size: the listing's 4 MB is a module property. The chip datasheet does not describe board flash, so it is omitted.
- Listing said 12 GPIO pins; not used. The chip variant table gives 22 GPIOs for the QFN32 package.
- Current consumption tables (section 5.6) and per-pin current and voltage limits are not transcribed.
- Listing's 3.7V LiPo note on VBAT is board-level and is not used.
- no official board pinout; pinout withheld. The ESP32-C3 SuperMini is a third-party board; the Espressif DevKitM-1 header is a different board and is not used. The chip datasheet pin table lists chip pins, not board header pins.

## Sources

- Espressif ESP32-C3 Series Datasheet v2.4 (official): [link](https://www.espressif.com/sites/default/files/documentation/esp32-c3_datasheet_en.pdf).
- Board-level facts (pin layout, flash, USB connector, dimensions) have no official source for this board, which is not an Espressif product.
