The outer headers J1 and J2 are the mikroBUS™ interface connectors, providing selectable 3.3V/5V power
input to the module and voltage translated digital I/O lines, including: UART receive/transmit lines and control
pins.
The header J3 provides configurable I/O expansion lines (inputs with weak internal pull-up by default),
powered at the internal logic voltage VDD.
The header J4 contains the main analog signals, such as microphone signals and amplified DAC outputs,
which are also available on the internal right angle connectors J5 and J6.
The module can also be operated through the programming connector J7 alone, by using the QuickUSB
adapter/cable.
