Ai-WB2-01M

Ai-Thinker · WiFi Modules · DIP-18

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.

CAD (KiCad official)

  • Symbol: Ai-WB2-01M
  • Footprint: Package_DIP:DIP-18_W7.62mm
  • 3D model: DIP-18 (KiCad packages3D, STEP)
  • 3D model files: ai-wb2-01m-etched.step / ai-wb2-01m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ai-wb2-01m.step / ai-wb2-01m.glb are the bare package body.
