It has connections for I2C (4 pin JST) and a 16 bit 4 channel A/D ADS1115 module (not supplied).

4 Digit Display With Bar Graph - Wemos Version


An 4 digit display with 0.56" high LED digits.

16 LED's in a bar grapgh design. Speaker for alert tones.

The board uses a MAX7219 and an Arduino library is available to get you up a running quickly.

MAX7219 0.56" 8 Digit Display


An 8 Digit LED display with a 0.56" Red LED display.

The board uses the MAX7219 display driver chip and can be driven from any micro-controller such as PIC, Arduino or ESP8266's.

Dot Matrix Controller Using a Wemos D1 Mini. Can be used with the 4 digit MAX7219 LED board listed below

The board mounts on the back of the matrix module and also has a socket for the popular Wemos D1 Mini ESP8266 module, plus a small speaker for alert tones and connections for additional I/O. The board mounts using 2off 5pin headers directly to the rear of the matrix board making a very simple and functional Wi-Fi enabled matrix display. It is also possible the connect several matrix boards all driven by the Wemos board to make a larger message display. Please note that the Wemos can only power 1 display module if more are used then an external 5V supply is required.

ESP8266 4 Digit Display With Rotary Encoder

The display is a 4 digit display using a MAX7219 display driver. The module is made up of two 2 digit LED displays, a 10 pin 2.54mm header is provided for connections. Also mounted on the board is a rotary encoder and a speaker with transistor driver. The speaker input is at logic level and active high, ideal for alert tones. ESP8266 options, either a Wemos D1 Mini or external Arduino/Raspberry Pi via a 10 way Header Connection (10 pin 2.54mm Header).

Compass Style LED Display

This compass style display has a two line 6 digit (3 plus 3) display using a MAX7219 display driver. The module is made up of two 6 digit LED displays plus 16 off 5mm LED’s in a compass layout with 22.5° increments. Connection is either via a 6 pin 2.54mm header, mounted on the rear. Making it ideal for use with any microcontroller including Arduino boards. There is also on the rear a two 8 pin socket for a Wemos D1 Mini ESP8266 development board.
