Wemos D1 Mini Pro Wifi Development Board with SMA Antenna and IPEX Cable

Wemos D1 Mini Pro Wifi Development Board with SMA Antenna and IPEX Cable

The Wemos D1 Mini Pro is a professional version of the ESP8266 module, offering increased memory, a longer range, and a more durable design. Based on the ESP8266EX, it provides 16MB of memory, quadrupling the capacity of the previous D1 Mini. The compact design features a ceramic antenna for a 90m line-of-sight range, and the board is optimized for robustness and versatility. It also supports an external 2.4G Wireless SMA Antenna for an extended range of up to 150m.
