| External Flash | 8 MB up to (QSPI Memory Expansion, board ready to solder additional 8MB Flash chip such as 25Q128JVSQ) |
| ESP-MESH | No |
| CAN | Yes 3 |
| GPIO | 55 input/output signal pins (42 are accessible when used with a solderless breadboard) |
| Hall effect sensor | No |
| Temperature sensor | Yes A built in temperature sensor allows reading the temperature inside the MCU chip |
| Touch sensors | No |
| I²C | Yes 3 |
| I2S | 2 (I2S/TDM) |
| ADC | Yes 18 pins total (12 bit, 2 Converters, 4 comparators) |
| DAC | No |
| PWM | Yes 31 pins/outputs (3x PWM 32 bit, 32x PWM 16 bit) |
| SDMMC | Yes 1 SDIO (4 bit) native Micro SD Card |
| RMT (remote control) | No |
| LCD Interface | No not dedicated |
| Camera Interface | No not dedicated |
| Deep sleep consumption | |
| Security | |
| Secure flash | |
| Cryptography support | Symmetric ciphers and one-way hash can be computed by hardware, but currently no library support exists to utilize this hardware. |
| Dimensions | |
