The on-chip or on-module flash memory which holds the application code. Don't mess with those pins

Good to know; but - I wish that that were somehow indicated here, instead of a big empty space:

To manage noise & power I'm setting unused pins on my ESP32C3 MINI 1 as such:


static const gpio_config_t unused = {
.pin_bit_mask =
(1u << GPIO_NUM_0)
| (1u << GPIO_NUM_1)
| (1u << GPIO_NUM_2)
| (1u << GPIO_NUM_3)
| (1u << GPIO_NUM_10),
.mode = GPIO_MODE_DISABLE,
.pull_up_en = GPIO ...
