What is it?

A UPDI Standalone Programmer for programming AVR/Attiny/Atmega Devices. This programmer will program the Attiny0 series, Attiny1 series and the Attiny2 series MCU's. It also supports the AVRDA and AVRDB devices as well as the Atmega0 series MCU's all without using a computer. Just load the hex files, set up configuration with a simple terminal program (For best results, use TeraTerm), the programmer now operates as a standalone programmer. To find out if this programmer supports the MCU you are using, please see the device list below. Untested Devices: Due to the chip shortages we are all facing these days, I am unable to purchase these MCU's at this time. Normally I do not release a programmer without physically testing every single MCU that it supports. However, the programmer is expected to work for the untested MCU's.

This programmer is great for mass production programming or for updating devices for customers. If you need to program multiple devices with the same code, the UPDI Standalone programmer really simplifies the operation! It Programs and Verifies Flash, Eeprom, Fuses, User Row and Lock Bits. Each operation can be enabled or disabled in the configuration.

The UPDI Standalone AVR Programmer operates through the one wire UPDI interface on your MCU. A three wire connection is required. (VCC, GND, UPDI). A cable is include with the programmer.

Why did you make it?

There is a growing need for an affordable standalone programmer that supports the UPDI protocol. There is no need to install a HUGE program on your computer just to program your MCU. The UPDI programmer is fast and reliable.

What makes it special?

You do need a computer to set it up initially, or whenever you want to change the hex files. The UPDI Standalone Programmer is configured to work best with TeraTerm (a simple terminal program). Once set up, The UPDI Standalone Programmer runs from the target power (3V or 5V only) or a USB power supply and can supply power to your target (3V or 5V only). The data (Flash, Eeprom, User Row, Fuse and Lock bits) are stored in the programmers memory until they are changed. Standalone operation is invoked when jumper J1 is installed. It just can't be any easier.

The UPDI Standalone ISP Programmer can also be password protected for preventing unauthorized usage. If you are purchasing this item, please check your email messages on Tindie for instructions.
