Arduino Nano As ISP (In System Programmer) ShieldDesigned by H2O2FromH2O in United States of America
The H2O2-Nano as ISP Shield is the Arduino As ISP Project on an Arduino Nano Shield. It provides Full Arduino As ISP functionality in a convenient compact shield, plus it adds several features that makes this open source project even better.
There are three LED's Broken out that give visual feedback about the programming process: HeartBeat, Error, Programming. And of course the Standard Arduino Nano LED'S are still visible.
Advanced Functionality includes multiple ISP/ICSP connector There are two 6 Pin ISP (In System Programmer) ports, one Male the other Female, which are standard in Arduino and used to program the boot loader or burning the configuration fuses. The pinout is [ 1:MISO | 2:+V | 3:SCK | 4:MOSI | 5:RESET | 6:GND ], and to make it backwards compatible there is a 10 pin AVR ISP connection for those with legacy hardware and cables. The pinout is [ 1: MOSI | 2:+V | 3:n/a| 4:GND | 5:RESET | 6: GND | 7: SCK | 8:GND | 9:MISO | 10:GND ]
There are 8Mhz and 16Mhz frequency outputs for simulating crystals when your CPU can't be programmed with out a crystal.
Main Program Write Protection:
The Arduino Nano CPU can be reflashed/upgraded or protected in circuit with the aid of a selectable capacitor via JP1
With this programmer you can upload sketches, burn configuration fuses and burn the bootloader on any Arduino (or other brand) AVR based boards through the ISP connector. By uploading a sketch with an external programmer you can remove the bootloader and use the extra space for your sketch.
Hey DIY'ers, make this project on your own. Get Just the board from here, and add your own parts.
Connection with the computer : Mini USB Via Arduino Nano Interface, Optional Cable Available
Some Supported CPU's: ATmega328pu, ATmega328au, ATmega1284 , ATtiny 45,84,85,2313,4323

Connection with the target board: 10 pin ISP (Optional) The pinout is [ 1: MOSI | 2:+V | 3:n/a| 4:GND | 5:RESET | 6: GND | 7: SCK | 8:GND | 9:MISO | 10:GND ]
On Board Frequency Source: 8Mhz and 16Mhz Frequency
◈ 1x H2O2-Nano As ISP Shield - Assembled and Tested, 10 Pin and 15 Pin Headers are Not Normally soldered; Option.
Your Arduino Nano Needs a Program So it can be a Programmer and it can be downloaded from here. H2O2 Nano as ISP Sketch If you find your self in a pinch, The ArduinoISP Sketch found in Examples with in the Arduino IDE will function, However two of the LED's and the Frequency outputs will not function.
No modifications are needed to burn programs, boot loaders or configuration fuses. Choose Programmer "Arduino As ISP"
When Burning Programs and circumventing the bootloader to increase usable program space, the following modifications are needed:
Follow this How to By Martyn Currey: Adding a new Arduino definition to the boards.txt file
When a Arduino Nano V3.0 clone is purchased with the H2O2-Nano As ISP Shield the Micro Controller is programmed and The necessary Configuration Fuses are set for you. However when the user supplies the Arduino Nano V3.0, The low_fuses on the Nano needs to be set to BF in order to activate the 16MHz Frequency. This can be a challenge because this programmer can not set its own fuses. A second AVR Micro Controller like Arduino Duemilanove, Nano, Mini, Pro Mini will be needed. The 8MHz Frequency Source will always be available. No other functions are affected when the low_fuses is left with its default value of FF
The Shields two 15pin headers that need to be aligned and mated with the Nano correctly. The H2O2-Nano As ISP Shield has white silk screen printing on all 4 corners. They should always be visible, there order is: (Tx, D12, D13, Vin). Most Arduino Nano V3.0's have Silk screened designaters for the pins, Line these up with the Shields Tx, D12, D13, Vin. See Picture Above!
