    This programmer is a compact solution for programming the 3pi robot through a USB port. The programmer incorporates a USB-to-serial adapter and emulates an AVR ISP programmer so that you can program your 3pi with any software that can talk through a serial port to an AVR ISP, such as Atmel’s AVR Studio and AVRDUDE, which is included in the open-source WinAVR package. The unit also doubles as a USB-to-serial adapter (TX and RX only), allowing you to communicate with your 3pi, or any other microcontroller, through a terminal program.

    A USB A to Mini-B cable is required but not included. These types of cables are common for digital cameras and other USB peripherals, so you might already have the necessary cable. The 6-pin ISP programming cable is included. The older, 10-pin ISP connections are not directly supported.

    Using the USB programmer
    Begin by following the USB-to-serial adapter driver installation instructions. Make sure you install the driver before you connect your programmer to the computer. The USB adapter will install as two devices (USB device and COM port); you can ignore Microsoft’s repeated warnings that the driver has not been tested by Microsoft. Once the driver is installed, your programming software can communicate with the programmer as if it were on a serial port.

    The programmer is powered through the USB port, but it does not deliver that power to the target device. Your target device must therefore be turned on to be programmed.

    The USB-to-serial adapter functionality can be accessed through the pads on the side of the PCB labeled TX, RX and G (for ground). The TX line (from the computer’s perspective--connect it to your target device’s RX line) is always connected, but the RX line needs to be switched using the shorting block in the middle of the board. Connecting it on the “P” side allows for programmer operation; the “U” side allows user USB adapter operation.

    Orangutan USB Programmer

    Works great! Simple to install (even on Windows 7) no driver signing necessary. Low power detection is great to prevent you from bricking your bot! I would have preferred it encased in some enclosure but it works.

    excellent maze robot

    the robot is excellent. the software enables one to programme it and download it and see what happens.

    yep it works

    nice bit of kit. download the s/w and use the interface to talk to the other stuff. no problems works like it says on the tin
