There are many documentations in pololu website. All documents are based on using pololu avr programmer as the programmer. But I think an Orangutan can be programmed via many devices such as Arduino, USBasp Programmer, USBtiny etc. But there are a little resources on using them in programming an Orangutan.
If you have any resources about it please explain. My Orangutan is resting beacause I don’t have a Pololu USB programmer. I have tried to program it using an Arduino Uno but I failed.
