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.
Bluetooth transmitter/receier module for serial communication with Arduinos and other microcontrollers
This module is bassed on the CSR standard bluetooth chip. It is a bluetooth transmitter and receiver that can connect to an arduino and allow serial communications to be sent to the arduino wirelesly from another bluetooth device such as a smartphone, a PC or another one of these modules.
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.
