 Recommended Sold Temperature Curve

Minimum User System

This module can work just at 3.3V working voltage:

Note

1. The working voltage for module is DC 3.3V;
2. The max current from IO of this module is 12mA;
3. Zigbee module is at download mode: D28 are High level, then module reset to power on;
4. Zigbee module is connected to RXD of the other MCU, and TXD is connected to RXD of the other MCU.

The Recommended PCB Design

• XT-ZB1 module can be sold on PCB board directly. For the high RF performance for the device, please notice the placement of the module. There are three ways to use the module for RF Module with PCB antenna.
• Solution 1: optical solution. The RF module is placed on the side of the board, and the antennas are all exposed, and there is no metal material around the antenna, including wires, metal casings, weight plates, and the like.
• Solution 2: sub-optical solution. The RF module is placed on the side of the board, and the antenna below is hollowed out. There is a gap of not less than 5 mm reserved with the PCB, and there is no metal material around the antenna, including wires, metal casings, weight plates, and the like.
  Solution 3: The RF module is placed on the side of the board, and the PCB area under the antenna is empty, and copper cannot be laid.
  

Peripheral Design Suggestion

XT-ZB1 module is already integrated into high-speed GPIO and Peripheral interface, which may be generated the switch noise. If there is a high request for the power consumption and EMI characteristics, it is suggested to connect a serial 10~100 ohm resistance, which can suppress overshoot when switching power supply, and can smooth signal. At the same time, it also can prevent electrostatic discharge (ESD).
