UPDI Standalone / Mass Production Programmer for Microchip AVR, ATtiny & ATmega Devices

The UPDI Standalone Programmer is designed for programming modern AVR microcontrollers quickly and easily. It supports ATtiny 0-series, 1-series, and 2-series devices, as well as AVR DA, AVR DB, AVR DD, and ATmega 0-series MCUs.

Simply load your HEX files and configure the programmer using a terminal program (TeraTerm is recommended). Once configured, the programmer operates completely standalone—no computer is required for programming. If you're unsure whether your MCU is supported, please refer to the device list below.

Ideal for Mass Production Programming

The UPDI Standalone Programmer is perfect for:

• Mass production programming
• Programming multiple devices with the same firmware
• Programming bootloaders into new microcontrollers
• Updating firmware in customer products

The programmer can Program and Verify:

• Flash Memory
• EEPROM
• Fuses
• User Row
• Lock Bits Each of these operations can be individually enabled or disabled through the configuration settings.

Fast Bootloader Programming

Programming bootloaders into brand-new devices is especially convenient. Simply load the bootloader HEX file, configure the required fuse settings, and store the data in the programmer's internal memory. The programmer can then repeatedly program identical devices in just a few seconds without requiring a computer.

Simple UPDI Connection

Programming is performed through the single-wire UPDI interface using only three connections:

VCC, GND, UPDI.

A programming cable is included.

Standalone Operation

There is a growing need for an affordable standalone programmer that supports the UPDI protocol. Unlike traditional programming solutions, there is no need to install large, slow, and resource-hungry windows application just to program your microcontroller. This programmer is fast, reliable, and simple to use.

A computer is only required during initial setup or whenever you want to change the stored HEX files or configuration. The programmer is designed to work with TeraTerm, a simple and free terminal program. After setup, the programmer operates from any USB power source or USB port.

It can:

• Supply 3.3V or 5V power to the target device, or
• Program a self-powered target operating from 1.8V to 5V

Note: The programmer cannot operate from the target's power supply. A USB power supply or battery pack is necessary.

All programming data—including Flash, EEPROM, User Row, Fuse settings, and Lock Bits—is stored in the programmer's internal memory until you choose to replace it. Standalone mode is enabled simply by installing jumper J1. It couldn't be easier. Please watch the video here.

Security

The programmer can also be password protected to prevent unauthorized use. After purchasing, please check your email for instructions and the user guide.

Technical Support

When you purchase this programmer, you'll receive direct support from the original designer—not a reseller. If you have any questions, simply send me a message through the marketplace or use the email address provided in the user guide. I usually respond very quickly and will do my best to help you successfully program your device. Unlike many low-cost products sold by anonymous resellers, I designed this programmer myself and fully understand both the hardware and software. That means you'll receive knowledgeable answers, honest advice, and reliable support whenever you need it.
