Arduino-compatible Circuit Signals
The mangOH Green’s integrated Arduino-compatible circuit is accessed via an on-board
ATmega32U4 micro-controller (U1500):
• UART—The ATmega32U4’s UART signal connects through a USB–UART FTDI (bridge) to the
primary CF3 module’s HSIC signal, as shown in
Figure 2-8 on page 22.
• USB—The ATmega32U4’s USB signal connects directly to a mini-USB connector (CN330) for
control by a connected computer.
