SW8B Xiao Expansion Board Serial Wombat PCB0037-16 ADC/GPIO / I2C Expansion Board Compatible with Seeed Xiao (2)
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•Easily add 16 more I/O or A/D channels to your Xiao based project through I2C. Two Serial Wombat SW8B chips provide 8 I/O pins each, and can be configured for I2C addresses 0x63, 0x64, 0x6B or 0x6C . 2200 ohm I2C pull up resistors are already on the bus for reliable communication
•Each expansion pin runs a state machine that can be assigned a specific function such as Servo, Rotary Encoder, A/D conversion, UART Bridge, PID control, PWM Generation, Kepad decoding, Frequency output, button debouncing, pulse timing and much more
•I2C Pull Up Solder Jumper must be soldered shut, or external I2C Pull Up resisors are required for proper operation.
•On board voltage regulator provides 3.3V to the Serial Wombat chips, avoiding overtaxing the Xiao's onboard regulator
•Optional on board power LED can be enabled by soldering a solder jumper closed.
•All Xiao pins are broken out for easy access. Additional PCB holes at both ends allow connection of additional I2C devices
•Many support videos and extensive documentation available online., along with open source hardware and software.
