ESP32-C5-WROOM-1U-N8R8 from Espressif Systems, in a ESP32-C5-WROOM-1U. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference for the module. |
| 2 | 3V3 | power_in | Power supply input with a recommended operating range of 3.0 V to 3.6 V (3.3 V typical), and the external supply must deliver at least 0.6 A. |
| 3 | EN | input | Chip enable: high enables the chip and low powers it off; the pin must not be left floating. |
| 4 | IO2 | bidirectional | GPIO2 with alternate functions MTMS, LP_GPIO2, LP_UART_RTSN, LP_I2C_SDA, ADC1_CH1 and FSPIQ. |
| 5 | IO3 | bidirectional | GPIO3 with alternate functions MTDI, LP_GPIO3, LP_UART_CTSN, LP_I2C_SCL and ADC1_CH2; MTDI is also a strapping pin for the SDIO clock edge. |
| 6 | IO0 | bidirectional | GPIO0 with alternate functions XTAL_32K_P, LP_GPIO0 and LP_UART_DTRN. |
| 7 | IO1 | bidirectional | GPIO1 with alternate functions XTAL_32K_N, LP_GPIO1, LP_UART_DSRN and ADC1_CH0. |
| 8 | IO6 | bidirectional | GPIO6 with alternate functions LP_GPIO6, ADC1_CH5 and FSPICLK. |
| 9 | IO7 | bidirectional | GPIO7 with alternate functions FSPID and SDIO_DATA1; it is also a strapping pin for JTAG signal source control and is floating by default. |
| 10 | IO8 | bidirectional | GPIO8 with alternate functions PAD_COMP0 and SDIO_DATA0. |
| 11 | IO9 | bidirectional | GPIO9 with alternate functions PAD_COMP1 and SDIO_CLK. |
| 12 | IO10 | bidirectional | GPIO10 with alternate functions FSPICS0 and SDIO_CMD. |
| 13 | IO13 | bidirectional | GPIO13 with alternate functions USB_D- and SDIO_DATA3. |
| 14 | IO14 | bidirectional | GPIO14 with alternate functions USB_D+ and SDIO_DATA2. |
| 15 | IO28 | bidirectional | GPIO28, which is a chip boot mode strapping pin and is pulled up by default. |
| 16 | IO5 | bidirectional | GPIO5 with alternate functions MTDO, LP_GPIO5, LP_UART_TXD, ADC1_CH4 and FSPIWP. |
| 17 | IO4 | bidirectional | GPIO4 with alternate functions MTCK, LP_GPIO4, LP_UART_RXD, ADC1_CH3 and FSPIHD. |
| 18 | IO27 | bidirectional | GPIO27, which is a chip boot mode and ROM message printing strapping pin and is pulled up by default. |
| 19 | NC/IO15 | bidirectional | Used as SPICS1 for the in-package SPI PSRAM and cannot be used for other functions in PSRAM modules; in modules without in-package PSRAM it can be used as GPIO15. |
| 20 | NC | unconnected | Not connected. |
| 21 | IO23 | bidirectional | GPIO23. |
| 22 | NC | unconnected | Not connected. |
| 23 | IO24 | bidirectional | GPIO24. |
| 24 | RX0 | bidirectional | UART0 receive signal (U0RXD), also usable as GPIO12. |
| 25 | TX0 | bidirectional | UART0 transmit signal (U0TXD), also usable as GPIO11. |
| 26 | IO25 | bidirectional | GPIO25, which is an SDIO sampling and driving clock edge strapping pin and is floating by default. |
| 27 | IO26 | bidirectional | GPIO26, which is a chip boot mode strapping pin and is floating by default. |
| 28 | GND | power_in | Ground reference for the module. |
| 29 | EPAD | power_in | Exposed ground pad; soldering it to the base board ground is optional but improves thermal performance when done with the correct amount of solder paste. |
| 30 | GND | power_in | Ground reference for the module. |
| 31 | ANT2 | bidirectional | RF input and output for the external antenna; it is disabled by default, with ANT1 used instead, and must be enabled by contacting Espressif. |
| 32 | GND | power_in | Ground reference for the module. |
