HC-06 Bluetooth Module
The HC-06 is a compact wireless serial interface module designed to enable Bluetooth communication between a microcontroller or embedded system and a master Bluetooth device (such as a smartphone, tablet or PC). It implements a transparent UART-to-Bluetooth link, meaning data transmitted into its RX/TX pins is sent wirelessly and received data is output on the serial pins, simplifying integration.
Engineered as a slave-only Bluetooth module operating under the Bluetooth 2.0 + EDR (Enhanced Data Rate) standard, the HC-06 abstracts away much of the complexity of wireless connectivity. Through simple UART commands and default baud rate (often 9600 bps) the module can pair with a master device, authenticate using a default pass-key (often “1234”) and then forward traffic transparently over the link.
Owing to its small physical size, minimal external components and UART interface, the HC-06 finds wide use in hobby electronics, embedded systems and IoT projects. It draws modest current, uses the 2.4 GHz ISM band (2.402-2.480 GHz), and allows devices without native Bluetooth capability to gain wireless serial connectivity. The simplicity of wiring and communication means it can often be dropped into an existing system with minimal redesign.
Features:
- Slave-mode only Bluetooth 2.0 + EDR module.
- Transparent UART interface for wireless serial data exchange.
- Operates in 2.402 GHz to 2.480 GHz ISM frequency band.
- Default baud rate commonly 9600 bps, default pass-key “1234”.
- Low power consumption suitable for embedded/battery-powered systems.
- Built-in 2.4 GHz antenna on many breakout versions.
- Simple wiring: VCC, GND, TXD, RXD (plus optional Key/State pins) for typical modules.

WeMos D1 ESP8266 WiFi Board (UNO Based)
The ESP8266 D1 R1 WiFi board utilizes the ESP8266 WiFi enabled processor, and puts it onto an Arduino Uno board footprint. It provides a way to work with the ESP8266 in a familiar setup and does not require a breadboard in order to make interconnections since it has the typical on-board female headers. It will also work with some Uno shields that have compatible I/O pin-outs.
Arduino Shield – Nano CNC Machine V4 Board
This board is widely used for driver expansion board of engraving machines. There are a total 3 3-way slots for stepper motor driver modules (Model A4988 or Drv8825 - It sold separately at our store), and it can drive 3-way stepper motors each up to 2A. Each way stepper motor has two I/O ports and it means 6 I/O ports can manage 3 stepper motors. It is very convenient to operate.
