3 Module Block Diagram 4 Hardware Design Amp’ed RF modules support UART, USB, SPI, and GPIO hardware interfaces. Please note that the usage of these interfaces is dependent upon the firmware that is loaded into the module, and is beyond the scope of this document. The AT command interface uses the main UART by default. Notes All unused pins should be left floating; do not ground. All GND pins must be well grounded.
4.2 GPIO Interface All GPIOs are capable of sinking and sourcing 4mA of I/O current. 4.3 UART Interface The UART is compatible with the 16550 industry standard. Four signals are provided with the UART interface. The TXD and RXD pins are used for data while the CTS and RTS pins are used for flow control.
