The WeMos d1 mini Pro is an improved version of the WeMos d1 mini developed by the Chinese company Wemos.cc. It is built around the Espressive SoC ESP-8266EX. Compared to her little sister, she brings three improvements. First, it is equipped with 16MB of flash memory instead of 4MB. The WiFi antenna engraved on the PCB has been replaced by a ceramic antenna of better quality. Finally, an IPEX connector can be used to add an external WiFi antenna. It is possible, for example, to increase reception when the network coverage is poor. An extension for an external antenna can also be used. Convenient if the Wemos Pro is installed in a metal cabinet that cages faraday or blocks the WiFi signal.
External WiFi antenna with IPEX connector
Like all development boards based on ESP8266, it is very easy to program it using the IDE Arduino or PlatformIO. It is supported natively by the Espressif SDK. All Shields developed for the WeMos d1 mini are compatible. We regret, however, the lack of support for extended memory (16MB) by the Espressif SDK at the moment.
