TinyLoadr AVR Programmer




finally finished the next version of my TinyLoadr AVR programming Shield – and it’s not a shield. It’s a standalone USB programmer, so you no longer have to have an extra Arduino laying around. The best part? It’s the same price as the shield was!

Read more to find out more about it, or visit my Tindie store to grab one for yourself!

TinyLoadr AVR Programmer




Features at a glance

  • Open source.
  • Supports a wide range of AVRs (see list below)
  • USB connector
  • 16MHz clock source for all supported AVRs
  • One 28-pin ZIF socket
  • A Blink LED to test your microcontrollers
  • 10 and 6-pin ICSP headers for programming target boards
  • Can power target boards with 5V
  • M3 (3.2mm) size mounting holes
  • Easy to use for both beginners and advanced users
  • Easy to use with both Arduino IDE and avrdude

What microcontrollers are supported?

The following DIP microcontrollers are supported in the ZIF socket:

  • ATtiny11
  • ATtiny12
  • ATtiny13
  • ATtiny15
  • ATtiny24
  • ATtiny25
  • ATtiny44
  • ATtiny45
  • ATtiny84
  • ATtiny85
  • ATtiny2313
  • ATtiny4313
  • ATmega8
  • ATmega48
  • ATmega88
  • ATmega168
  • ATmega328P

On target boards, any microcontroller that avrdude supports is supported, though Arduino cores may not exist for all of them. Any pin-compatible AVRs will also work (that is, one with the same pinout).

The programmer may not work with microcontrollers with more than 64K of flash (e.g, ATmega1281/1280/2561/2560).

It’s pretty easy to use

The TinyLoadr AVR Programmer was designed to be very simple to use. When programming a microcontroller with the ZIF socket, you simply set the “uC Select” jumper to the appropriate microcontroller, and insert the microcontroller as shown in the photos. For programming with the ICSP headers, just attach your ICSP ribbon cable to the programmer and your target board and you’re ready to roll.

What changed, and why?
2 years ago I designed my first PCB – an Arduino shield that made it easier for me to program ATMega and ATtiny microcontrollers with my Arduino. I called it the ArduinoISP Shield (later renamed to the TinyLoadr Shield to avoid any issue using the Arduino name). After building my own, I still had 9 PCBs left. I decided to order parts to build them and sell them on Tindie. I did, and people loved them. Over the next 2 years, I designed through 4 variations of the shield, adding new features and making it look nicer. Well, I’ve done it again, and I really hope people will like it.
