## Description

**Note:** Pololu have released a second-generation, general-purpose **[USB AVR programmer](https://core-electronics.com.au/pololu-usb-avr-programmer.html)** that Pololu recommend over this programmer as it is better in almost every way. The Orangutan USB programmer is now only available by large-volume special order. Please [contact us](https://core-electronics.com.au/contact) Pololu if you are interested.

## Overview

This programmer is a compact solution for programming Pololu's [Orangutan](https://core-electronics.com.au/catalog/product/view/sku/POLOLU-225), [Orangutan SV-328](https://core-electronics.com.au/orangutan-sv-328-robot-controller.html), [Orangutan LV-168](https://core-electronics.com.au/orangutan-lv-168-robot-controller.html), and [Baby Orangutan](https://core-electronics.com.au/baby-orangutan-b-328-robot-controller.html) robot controllers through a USB port. It can also program Pololu's [3pi robot](https://core-electronics.com.au/pololu-3pi-robot.html). Pololu's programmer incorporates a [USB-to-serial adapter](https://core-electronics.com.au/pololu-usb-to-serial-adapter.html) and emulates an AVR ISP programmer so that you can program your Orangutans or 3pi with any software that can talk through a serial port to an AVR ISP, such as Atmel’s AVR Studio 4 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 Orangutan, 3pi, or any other microcontroller, through a terminal program.

A [USB A to Mini-B cable](https://core-electronics.com.au/usb-cable-a-to-mini-b-6-ft.html) 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](https://core-electronics.com.au/6-conductor-ribbon-cable-with-idc-connectors-12.html) (pictured to the right) 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. Be careful about the pin 1 orientation with the Baby Orangutan, which does not have a [shrouded ISP connector](https://core-electronics.com.au/shrouded-box-header-2x3-pin-0-100-2-54-mm-male.html). The red wire and mark on the ISP connector should be lined up with the arrow to pin 1 on the Baby Orangutan PCB. The Orangutan, Orangutan SV-xx8, Orangutan LV-168, and 3pi robot all have keyed shrouded headers that enforce proper orientation of the ISP cable.

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.

Please see Pololu's Orangutan USB Programmer User’s Guide for more detailed information, usage instructions, and troubleshooting help.

**Note:** [USB cable](https://core-electronics.com.au/usb-cable-a-to-mini-b-6-ft.html), Orangutan robot controller, and software are **not** included. The programmer should be able to program all AVRs that support paged program and EEPROM memory, but Pololu can only support Orangutan and 3pi programming at this time.
