Ever had to design a project with limited space, only to find that you were running out of room for that bulky 6 pin connector?
Well this little device allows you to use the uSD card reader as the Arduino ISP connector by breaking out the 6 pin header to contacts on the PCB which mimic a uSD card. Once the target device is bootloaded, you can remove this adapter and you are left with a functioning uSD port. The Arduino Reset signal is carried by pin 8 of the uSD card connector, making use of a N/C terminal disregarded by the uSD card itself.
The device also contains circuitry to power the target device, allowing ease of use when programming multiple target devices.
