Z2芯片对上电时序有要求,在上电过程中 RST 引脚达到 1.62V 以后系统开始启动,这个时候 VCC 需要在 10ms 内达到 1.8V 以上。由于 RST 引脚有 RC 链路,故裸模组在 RST 达到 1.62V 的时候 VCC 已经超过 1.8V。
Z2 芯片模组对接的电源驱动如果存在大电容的一些充放电情况下,若模组电压未完全放电到 0.6V 以下,模组再启动的话会有死机风险。要求模组 VCC_3.3V
供电引脚需要接 1K 的假负载用来快速释放电能。可参考下面的部分电源驱动链路:
由于模组串口对接有倒灌电压,可通过对模组 CEN 或 RST 引脚拉低,降低模组不工作时的功耗来实现整机低功耗。
如图所示,MCU 通过 GPIO 口控制模组的 CEN 或 RST 引脚,实现对模组的通断电操作。当有数据需要上报时,GPIO 口输出高电平,模组上电,串口通信建立连接,MCU 通过模组将数据同步到云端和客户端。当数据上报完成后,GPIO 口输出低电平,模组处在复位状态,模组低功耗。缺点:模组 CEN 或 RST 引脚内部有 10K 上拉电阻,当模组处在复位状态时,模组的输入电流仍有 330μA。
ZT2S 使用的是板载 PCB 天线,天线增益 2 dBi。
为确保 RF 性能的最优化,建议模组天线部分和其他金属件的距离至少保持 15mm 以上。如果使用环境的天线周边包裹金属材料等,会极大地衰减无线信号,进而恶化射频性能。成品设计时,注意给天线区域预留出足够的空间。
用户 PCB 板在天线区域勿走线甚至覆铜,以免影响天线性能。
