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.

USB Programmer for Sonoff Relays

A USB programmer is for the ESP8266 used on the Sonoff Relay modules.

To set the ESP8266 into programming mode.
Press and hold the push button on the Relay board (GPIO0).
Press and release the power button on the programmer.
Program the device and keep the relays push button pressed until done.

Raspberry Pi Power and Fan Controller V2

MOSFET driver for 5V 40mm Fan - GPIO17.
Connection for +5V input (to power the Pi) or output.
Solder pads for GPIO24 and GPIO25 for external relay board or other.
40 pin GPIO header and 2 pin header for the fan.
Status LED connected to +3.3V from the Pi.

ESP-01 Temperature and Humidity Sensor

This simple board connects an ESP-01 Wi-Fi module to a AM2301 Sensor. Ideal for a simple indoor wireless sensor for temperature monitoring or control.

ESP Programmer

A USB programmer for the ESP8266 or ESP32 chips from Espressif Systems. This board uses the CH340 USB to serial interface to program the ESP devices. The board also uses the GPIO0 and Reset lines to aid programming, just as Wemos and NodeMCU development modules.

Using an external programmer makes the target board easier and cheaper to build without the USB interface, this also aids with lower power modes used for battery operation. Not having to power the USB interface can save precious battery power.

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.

Raspberry Pi Power and Fan Controller

MOSFET driver for 5V 40mm Fan - GPIO17.
Connection for +5V input (to power the Pi) or output.
Solder pads for GPIO24 and GPIO25 for external relay board or other.
40 pin GPIO header and 2 pin header for the fan.
Status LED connected to +3.3V from the Pi.

Display colour: RED
Operating Voltage: 5V
Dimensions: 230mm x 32mm x 19mm
Module with input and output interfaces, support for cascading multiple modules
The left side of the module to the input port, the right to an output port

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).

ESP8266 Mains Power Sensor

Single phase mains power sensor using a current transformer (not included) and a Wemos D1 Mini (not included). The transformer used is a "Current Transformer AC current sensor 100A SCT-013-000" available on eBay. This plugs into the sensor PCB and the ESP8266 (Wemos D1) and uses the analog input to measure the mains current draw. The Wemos is powered by it's micro USB input. This makes a very simple sensor setup that could report the measured current via MQTT. A simple case design is also available on Thingiverse.

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.
