Board topside markings SDA, SCL would seem to indicate support for I2C. Documentation received from Hiletgo support is inconsistent. They sent a datasheet for TTP229 variant (LSF) which supports I2C. However, their own schematic and IC topside marking indicate that IC is actually TTP229-BSF, which does Not support I2C, only serial clocking in data. Think: I2C minus addressing, framing, acknowledgements, and defaulted to active-low.
