Safe Pins to Use
These pins are safe for general GPIO usage without boot or system conflicts.
Pins to Avoid or Use with Caution
Reserved for critical functions. Misuse may cause boot failures, programming issues, or system conflicts.
| Pin | Label | Why Avoid | Type |
|---|---|---|---|
| IO1 | U0TXD (GPIO1) | Connected to on-board USB-UART for uploading and logs; drives serial output at boot, so using as GPIO can disrupt programming or console. | ๐ USB |
| IO2 | GPIO2 | If driven HIGH on reset (while IO0 is LOW), selects an unsupported SDIO boot mode, causing boot failure. | ๐ ๏ธ Strapping |
| IO3 | U0RXD (GPIO3) | Used for receiving data from USB-UART (programming); also pulled HIGH at boot for console communication, so using as GPIO can disrupt uploads. | ๐ USB |
| IO16 | GPIO16 | Connected to internal PSRAM on PSRAM-enabled modules; not usable as GPIO on those modules. | โก Flash |
| IO17 | GPIO17 | Connected to internal PSRAM on PSRAM-enabled modules; not usable as GPIO on those modules. | โก Flash |
