WIFI D1 mini - USB-TTL ch340 Converter Shield (Serial programmer ) (Per Piece)

Working directly with ESP 12 or ESP 07 WiFi modules can be difficult due to their small size and lack of onboard USB programming support. This USB TTL adapter board with CH340 USB to serial converter is designed to solve that problem by allowing ESP 07 or ESP 12 modules to be soldered directly onto the board. Once installed, the module becomes functionally similar to a D1 mini style development board and can be programmed easily using a USB cable without any external programmer.

Package Includes

  • 1 x USB TTL Adapter Board with CH340
  • 2 x Male Pin Header 1x8 pins
  • 2 x Female Pin Header 1x8 pins
  • 2 x Stackable Pin Header 1x8 pins
