Summary of EGYDuino – Arduino compatible board
EGYDuino is a cost-effective, single-sided PCB Arduino clone compatible with standard Arduino boards. It utilizes the ATmega8 for USB-to-serial communication and supports ATmega168/328 cores via bootloaders. The design features through-hole components, a 5V regulator, dual power options (USB or DC), and full pin compatibility, making it easy to fabricate at home using standard methods.
Parts used in the EGYDuino:
- ATmega8
- ATmega168
- ATmega328
- Single sided PCB board
- AVR-CDC232 firmware
- ArduinoNG bootloader
- Arduino Duemilanove bootloader
- 5V regulator
- 3.3V output component
- Standard RESET button
- LED for PIN13 with Jumper
- LED for power
- ICSP PINs
- USB or DC power switch
- Standard DC power jack
- Through hole parts
EGYDuino is a DIY Arduino clone made on a single sided PCB board. It’s simple and cheap to build using home PCB fabrication methods and it’s 100% compatible with Arduino.
Description
ATmega8 takes care of the USB to serial communication and should be burned with AVR-CDC232 firmware. AVR-CDC creates a virtual COM port on the PC after connecting the device and installing the appropriate driver. The ATmega 8,168 should be programmed with ArduinoNG boatloader.
This can be done through another Arduino board (set a ISP programmer) using the Arduino IDE or by using a separate programmer (USB, serial or parallel) like USBasp with suitable software. Also you can use Arduino Duemilanove bootloader for ATmega 168 or 328. The features of this board are:
- It’s using ATmega8 as interface IC
- Has USB connection to PC
- Standard RESET button
- 100% compatible Arduino PINs
- 5V regulator
- 3.3V output
- compatible size and design
- All component are TH (through hole) parts
- USB or DC power switch
- LED for PIN13 with Jumper
- LED for power
- ICSP PINs
- easy to build
- ATmega8,168,328 core using arduinoNG
- standard DC power jack
EGYDuino can be powered via the USB connector, or with a voltage regulator through an external adapter.
