InterfacePrecautions
Power inputPower only from the DC jack; minimum 2A supported when no peripherals are attached
MICDo not reverse the positive/negative leads; route MIC wires away from high-speed and power lines
RTCDo not reverse the battery polarity; if the clock drifts, replace with a CR2036 (3V) coin cell
DEBUG serialDefault 1500000bps; 3.3V logic — level shifting needed for devices above 3.3V
TPI2C touch panels only; connect the panel before powering on; no hot-plugging
40pin IO3.3V level; level shifting needed for peripheral IO above 3.3V; mind input/output direction
