Ai-WB2-01M from Ai-Thinker, in a DIP-18. 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 pin for the module (datasheet function: 接地, ground). |
| 2 | VDD | power_in | 3.3V supply input; the datasheet recommends an external supply able to provide more than 500mA. |
| 3 | TX0 | output | UART0 transmit (TXD), also multiplexed as GPIO16, SPI_MOSI/MISO, IIC_SCL and PWM_CH1. |
| 4 | RX0 | input | UART0 receive (RXD), also multiplexed as GPIO7, SPI_SCLK, IIC_SDA and PWM_CH2. |
| 5 | IO20 | bidirectional | General-purpose I/O GPIO20, also multiplexed as SPI_MOSI/MISO, IIC_SCL and PWM_CH0. |
| 6 | IO12 | bidirectional | General-purpose I/O GPIO12, also multiplexed as SPI_MOSI/MISO, IIC_SCL, PWM_CH2 and ADC_CH0. |
| 7 | IO14 | bidirectional | General-purpose I/O GPIO14, also multiplexed as SPI_SS, IIC_SCL, PWM_CH4 and ADC_CH2. |
| 8 | 8/NC | unconnected | Default NC and not usable; if brought out, it supports Bootstrap/GPIO8/SPI_MOSI/MISO/IIC_SCL/PWM_CH3, and must be used only after contacting Ai-Thinker. At power-up, a high level enters burn mode while a low level boots normally. |
| 9 | EN | input | Default chip enable, active high. |
| 10 | IO4 | bidirectional | General-purpose I/O GPIO4, also multiplexed as SPI_MOSI/MISO, IIC_SCL, PWM_CH4 and ADC_CH4. |
| 11 | IO3 | bidirectional | General-purpose I/O GPIO3, also multiplexed as SPI_SCLK, IIC_SDA and PWM_CH3. |
| 12 | IO2 | bidirectional | General-purpose I/O GPIO2, also multiplexed as SPI_SS, IIC_SCL and PWM_CH2. |
| 13 | IO22 | bidirectional | General-purpose I/O GPIO22, also multiplexed as SPI_SS, IIC_SCL and PWM_CH2. |
| 14 | IO21 | bidirectional | General-purpose I/O GPIO21, also multiplexed as SPI_MOSI/MISO, IIC_SDA and PWM_CH1. |
| 15 | IO17 | bidirectional | General-purpose I/O GPIO17, also multiplexed as SPI_MOSI/MISO, IIC_SDA and PWM_CH2. |
| 16 | IO11 | bidirectional | General-purpose I/O GPIO11, also multiplexed as SPI_SCLK, IIC_SDA and ADC_CH10. |
| 17 | IO1 | bidirectional | General-purpose I/O GPIO1, also multiplexed as SPI_MOSI/MISO, IIC_SDA and PWM_CH1. |
| 18 | IO0 | bidirectional | General-purpose I/O GPIO0, also multiplexed as SPI_MOSI/MISO, IIC_SCL and PWM_CH0. |
