I2C Paralel to 2 Pin Serial converter for Arduino type LCD screens
This converter can be soldered directly to a standard 1602 LCD screen to convert it to the more convenient 2 pin serial (I2C) used in many Arduino projects.
There is a removable jumper to allow connection with both backlit and non backlit screens.
A potentiometer can adjust the brightness & contrast of the LCD.
2.4GHz Serial WiFi module for Arduino and other IOT or microcontroller projects
This module uses the popular ESP8266 microchip with full function WiFi as well as its own microcontroller. This module can be used to add WiFi to your microntroler project or can be programed directly from the arduino IDE to work independently. This module also has a built in regulator so it can be powered directly from 5VDC. Supplied with 8 way header.
This programmer makes setting up the ESP-01 much easier and safer, the ESP-01 just plugs into the 8 way header on the programmer and will be provided with the correct working and programming voltages. The module uses the popular CH340 USB-UART bridge to allow the ESP-01 to easily comunicate with the USB.
Voltage : 5VDC (from USB)
Dimensions : 17mm x 34mm (49mm including USB plug)
This module uses the DS1307 chip, which can be used for keeping time in a very wide variety of projects. For example it can be used to add time stamps to sensor readings, display the time accurately or keep track of time even when there is no power supplied (although it will require a rechargeable CR2032 battery for this). The Tiny RTC supports the I2C protocol, which makes it very easy to interface with many microcontrollers.
Specs:
VCC: 5V DC
Battery (optional): CR2032
Power consumption: <500nA (in Battery Backup Mode)
RAM: 56 Byte, non-volatile
Memory: 32kb EEPROM
Dimensions: 27mm x 28mm x 8.4mm
