3 Module Block B Diag gram 4 Hardwarre Design Amp’ed RF F modules su upport UART T, USB, SPI,, and GPIO hardware intterfaces. Ple ease note tha at the usage of these t interfaces is dependent upon the firmware that is loa aded into the e module, and is beyond the e scope of this documentt. The AT com mmand interrface uses the main UAR RT by default. Notes An external e Low Power Oscillator is requiired on pin 15. All unused pins should s be left ft floating; do o not ground.
4.2 GPIO Interface All GPIOs are capable of sinking and sourcing 6mA 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.

External LPO Reference Circuit 4.7 Audio Application Reference Design TBD 5 Regulatory Compliance This module has been tested and found to comply with the FCC Part15 and IC RSS-210 rules. These limits are designed to provide reasonable protection against harmful interference in approved installations. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance the instructions, may cause harmful interference to radio communications.
(A) If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: X3ZBTMOD8” or “Contains FCC ID: X3ZBTMOD8.
