ESP-12S Industrial WiFi Module

ESP-12S Serial WIFI Module
ESP-12S continues the excellent design of its predecessor, the package, pin definition, dimensions, etc. are consistent with the previous generation of ESP-12 series, which allows you to seamlessly embed it into existing products, eliminating the hassle and cost of revamping, prototyping, and re-testing. The design experience of the previous generation of products has been combined and rethought to pursue quality in every aspect of details such as impedance matching, alignment angle, distance, width, hole digging, copper laying method, and so on. After carefully considering the process and details of the module and exhaustively completing every design detail related to it, we found that both the product stability and anti-interference ability, as well as the transmitting distance, have been substantially improved! Finally, it has obtained FCC and CE certificates from SGS, the authoritative certification body designated by the European Union! It clears the obstacles for exporting to "foreign countries" such as Europe and America, and also the module itself has good RF performance.
