Adafruit released a newer and smaller ATtiny programmer – UPDI Friend
https://www.electronics-lab.com/adafruit-released-a-newer-and-smaller-attiny-programmer-updi-friend/
If you have ever programmed an AVR microcontroller with a USB to serial adapter, you should know how it sometimes gets messy with all the data and power wires. Therefore, Adafruit created a UPDI programmer tool that can program newer tinyAVR and megaAVR chips with only 3 wires! What is UPDI? UPDI stands for Unified […]
DIY UPDI USB Programmer is Low-Cost Alternative to Ready-Made Programmers
https://www.electronics-lab.com/diy-updi-usb-programmer-is-low-cost-alternative-to-ready-made-programmers/
A UPDI USB programmer (Unified Program and Debug Interface) is basically an Atmel / Microchip proprietary programming interface used for some AVR microcontrollers like the ATtiny series. AVR is an 8-bit RISC architecture microcontroller that is developed by Atmel. With the newer generations of technology, Microchip started releasing a new series of ATtiny chips called […]
SerialUPDI Programmer – Simple UPDI programmer for tinyAVR
https://www.electronics-lab.com/serialupdi-programmer-simple-updi-programmer-for-tinyavr/
Simple UPDI programmer for tinyAVR, megaAVR and AVR-Dx microcontrollers with voltage selection switch (5V and 3.3V). The programmer works with pyupdi as well as with the Arduino IDE as “SerialUPDI with 4.7k resistor or diode”. It is based on the USB-to-serial chip CH340N.

OMZLO Programs the new TinyAVR MCUs
https://www.electronics-lab.com/omzlo-programs-baremetal-on-the-new-tinyavr-mcus/
OMZLO has posted details about baremetal programming on the new TinyAVR MCUs. In their blog post, they describe how to program a blinky firmware on an Attiny406, from the ground up, using the simplest tools. Most of the things described can be easily transposed to other TinyAVR MCUs. About the programming, they say: “Our approach is generally […]
microUPDI – Pro-Micro Based UPDI Programmer
https://www.electronics-lab.com/microupdi-pro-micro-based-updi-programmer/
Thanks to the increased popularity of the recent ATtiny series of microcontrollers, there has been an increase in the number of open-source UPDI programmers out there. We have covered quite a number of them including the brilliant UPDI programmer compatible with Arduino IDE but we certainly have not seen the end of new designs. One […]
DIY Arduino Nano HV UPDI Programmer
https://www.electronics-lab.com/diy-arduino-nano-hv-updi-programmer/
In May, Arduino released a guide on how you can create a UPDI programmer for under $10. Now Dlloydev has posted a guide on Github how to make an Arduino Nano HV UPDI programmer. The Nano HV UPDI programmer will enable you to use the additional configuration settings for the UPDI pin without the fear […]
UPDI programmer compatible with Arduino IDE
https://www.electronics-lab.com/updi-programmer-compatible-arduino-ide/
Antti Mäntyniemi designed this board, which is a UPDI programmer that utilizes Arduino IDE to program AVR microcontrollers. This kind of programmer is used to programm the new 0-series and 1-series ATtiny mcus using Arduino IDE. The project files are available on github.com so you can build your own programmer.
Program ATtiny 0-Series Chips with a Miniature UPDI Dongle
https://www.electronics-lab.com/program-attiny-0-series-chips-miniature-updi-dongle-2/
Thanks to their tiny size and improved capabilities, the ATtiny-0-Series of microcontrollers have been a delight for designers and DIYers looking for a microcontroller with the ease of use associated with the Arduino boards, but with a way smaller form factor associated with ATtiny microcontrollers. Along with the ATtiny-1-series, the ATtiny-0-Series microcontrollers were meant to […]
Program ATtiny 0-Series Chips with This Miniature UPDI Dongle
https://www.electronics-lab.com/program-attiny-0-series-chips-miniature-updi-dongle/
This is a USB-stick sized UPDI programmer, for programming Microchip’s new 0-series and 1-series ATtiny chips from the Arduino IDE. It’s based on an ATmega328P, and is essentially an Arduino Uno on a USB stick, so you also could use it as a mini-sized Arduino Uno. by David Johnson-Davies: Starting in 2016 with the ATtiny87 […]
