TYWE2S 是由涂鸦智能开发的一款低功耗嵌入式 Wi-Fi 模组。它由一个高集成度的无线射频芯片 ESP8285 和少量外围器件构成,内置了 Wi-Fi 网络协议栈和丰富的库函数。
TYWE2S 内嵌低功耗的 32 位 CPU、1Mbyte 闪存、50KB SRAM 和丰富的外设资源。
TYWE2S 是一个 RTOS 平台,集成了所有 Wi-Fi MAC 以及 TCP/IP 协议的函数库。用户可以基于这些开发满足自己需求的嵌入式 Wi-Fi 产品。
TYWE2S 共有 2 排引脚,引脚间距为 2mm。
TYWE2S尺寸大小:17.3mm±0.35 (L)×15mm±0.35 (W) ×2.9±0.15mm (H),其中 PCB 厚度 0.8mm±0.1 mm。

PCB 板载天线接入,增益 3.0dBi。
在 Wi-Fi 模组上使用 PCB 板载天线时,为确保 Wi-Fi 性能的最优化,建议模组天线部分和其他金属件距离至少在 15mm 以上。
用户 PCB 板在天线区域勿走线甚至覆铜,以免影响天线性能。布局要点是:确保印制天线正下方或者正上方没有基板介质。确保印制天线的周围远离金属铜皮,这样可以最大程度上保证天线的辐射效果。
本模组暂无天线连接器。
说明:默认的尺寸公差为± 0.35mm,关键尺寸如果客户有明确要求,请沟通后在规格书中进行明确的标定。
