Just what I needed! Great little breakout

- ATtiny841 development board
Very clean little breakout for the ATTiny841, which has two hardware UARTs - great for communication projects!

Assembly looks very professional.

*When ordering with the 20Mhz xtal, keep in mind that is technically "over-clocking" the ATTiny841, which is no problem at all - after some quick googling, I was able to have the correct oscillator settings configured in the chip, using Atmel Studio.

Thanks again!

Great product and service

- ATtiny841 development board
Bought a number of these boards for a project, all arrived on time and functioned as advertised. Needed additional information and the response was immediate and courteous.

Great product, works as expected

- ATtiny841 development board
I needed a breakout board for developing a product based on the ATtiny processors. I didn't know the final pin count so I chose this board as one that will definitely have enough pins for my requirement. A big part of my decision to use this board was the ISP header in place and the reset switch already on the board. I also want to use the internal oscillator and the option to order without the crystal suited me perfectly.

I replaced the CPU three times on one of the PCB's because I kept discovering new ways of bricking the processor. I'm glad to say that the PCB is still in perfect condition where I replaced the CPU.

Overall it is a high quality product. A few pieces of example code for using the on-chip peripherals would be a great addition. Once I have finished my development I will share my code to drive the ADC. The photo shows the board on my hand built test board for my product with the Atmel ICE plugged into the ISP connector.

Essential for breadboard-based experimentation

- ATtiny841 development board
This board is great for anyone wanting to try out the new ATtiny841 with its much-expanded set of peripherals over the previous ATtiny84. As Atmel don't make the tiny841 in a DIP form factor, a board such as this is essential if you want to actually put it on a breadboard to play around with it.

While you could just use any old 14-pin SOIC-to-DIP adapter, this board in particular is built specifically for the chip and comes with decoupling cap, reset button and most importantly the ISP connector header allowing you to reprogram the chip in-place on the breadboard, thus speeding development time even further.

Also the silk-screen printing shows the pin names in their original Atmel naming scheme, making it easy to identify the pins inplace without having to constantly be cross-referencing against the datasheet. Useful when hooking up the wiring on your breadboard.
