ACROBOTIC WeMos ESP8266 D1 Mini 8×8 Dot Matrix Shield for Arduino NodeMCU Raspberry Pi WiFi IoT Red LED

The WeMos D1 Mini family of boards is one of the latest additions to the ESP8266-based IoT ecosystem. The WeMos D1 Mini 8×8 Dot Matrix Shield allows you to add a super-bright array of 64 red LEDs to your WeMos mini or mini Pro development boards. The WeMos D1 Mini Dot Matrix Shield is designed so that pins D5 (CLK) and D7 (DIN) are connected to the TM1640 LED driver digital interface onboard. Controlling the TM1640 is done over a serial interface, which uses a Start and Stop condition similar to what is found in the I2C bus. But, the data exchange occurs similarly to what is found in the SPI bus, without the use of a Chip Select (CS) line. A few software library options exist to get started with this shield. What makes the WeMos family of development boards for the ESP8266 great is the availability of stackable, plug-and-play shields such as this WeMos D1 Mini Dot Matrix Shield. Without much fuss, it's very easy to connect, control, and monitor a wide variety of electronic components to the ESP8266. The WeMos family is a great solution for building projects quickly using the ESP8266 SoC. Different users have different applications for the WeMos shields, thus we've found that the easiest way to please everyone is to ship the boards with the headers unsoldered. Each board in this kit includes a pair of Male, Female, Long Female pin headers for you to choose. Soldering is required for installing the header pins! Features: Control Interface: Serial (pins D5 (CLK) and D7 (DIN)) Input Voltage: 0.5~7VDC GRID Output Current: 20mA We have written useful guides for getting you started with the WeMos D1 Mini 8×8 Dot Matrix Shield: http://youtube.com/acrobotic
